Upgrading and Migrating

Introduces upgrades in Umbraco, describing what to consider when planning an upgrade.

What is involved in an upgrade

When upgrading to a new version of Umbraco, there are four key aspects of the migration to be aware of.

Database schema and content

Firstly there's the update of your Umbraco database's schema and how the content is stored. On occasion changes are necessary to support a new feature. This might be adding new tables or columns, or updating the stored data. This is something Umbraco takes care of for you. When Umbraco starts up and is running a newer version, the necessary changes will be detected and applied.

As a developer responsible for the Umbraco website, there's nothing specific you need to do here. We will communicate key migrations that will happen on major version upgrades. As if you have a large site and significant amounts of data need to be updated, the migration could take some time to complete.

Minor or patch versions may contain schema and content updates too, but they won't be extensive.

Supported features

Secondly you should review your use of property editors to ensure that they are available on the new version. It's rare for these to be removed, but it can happen when better alternatives are available. These are only removed in major versions and with plenty of notice on the announcements repository. Property editors for retirement will also have been indicated as legacy on earlier versions.

Project customizations

The third aspect is determining and verifying that your own code customizations are compatible with the new version. This includes C# server-side functionality, Razor templates and JavaScript backoffice extensions.

Extensive efforts are made to avoid breaking changes that would cause issues for these types of customization other than in a major version update.

Finally you should consider the packages you are using on your project. You will need to verify that the package will work with the new version of Umbraco. Or that a compatible upgrade of the package is available or planned.

As above, breaking changes that would prevent packages from working other than in a major version update are avoided.

For the reasons described, projects always need to be considered case by case when upgrading to new versions.

Umbraco communicates about the breaking changes in release blog posts and on the documented . There will be extended release candidate periods to ensure upgrades can be tested and to help package developers support new major versions.

Breaking changes are minimized but there will be cases when such updates are needed. How straightforward the upgrade will be depends on the breaking changes included in the major and whether your project(s) are impacted by them.

The following lists a few things to be aware of before initiating an upgrade of your Umbraco CMS project.

  • Sometimes, there are exceptions to general upgrade guidelines. These are listed in the . Be sure to read this article before moving on.

  • Ensure your setup meets the for the new versions you will be upgrading your project to.

  • Things may go wrong for different reasons. Be sure to always keep a backup of both your site's files and the database. This way, you can always return to a version that you know works.

  • - how to upgrade Umbraco across major, minor, and patch versions.

  • - configure Umbraco to upgrade in an unattended mode, avoiding the need to click through the installation wizard.

  • - details of changes to be aware of when upgrading to specific versions.

  • - covers the possibility of downgrading to a previous version and re-running migrations from an upgrade.

Before upgrading to a new major version, check if the packages you're using are compatible with the version you're upgrading to. On the package's page on the
, check the "Umbraco versions" field.

Upgrade from Umbraco 8 to the Latest Version

Learn how to upgrade your Umbraco 8 project to Umbraco 10.

It is currently not possible to upgrade directly from Umbraco 8 to the latest version.

The recommended approach for upgrading from version 8 to the latest version is to use this guide to upgrade from Umbraco 8 to Umbraco 10. Umbraco 10 contains the that must be upgraded from Umbraco 8. You can then use the steps to upgrade from Umbraco 10 to the latest version.

Since the underlying framework going from Umbraco 8 to the latest version has changed, there is no direct upgrade path. That said, it is possible to re-use the database from your Umbraco 8 project on your new project in order to maintain the content.

It is not possible to migrate the custom code as the underlying web framework has been updated from ASP.NET to ASP.NET Core. All templates and custom code will need to be reimplemented.

You also need to make sure that the packages you are using are available on the latest version.

Prerequisites

  • A Umbraco 8 project running the latest version of Umbraco 8.

  • A backup of your Umbraco 8 project database.

  • A clean installation of the latest version of Umbraco.

  1. Create a backup of the database from your Umbraco 8 project (after you have upgraded to the latest version of v8). For this, you can use the .

  2. Import the database backup into SQL Server Management Studio.

  3. Update the connection string in the new projects appsettings.json file so that it connects to the Umbraco 8 database:

  1. Run the new project and login to authorize the upgrade.

  2. Select "Upgrade" when the upgrade wizard appears.

  3. Once the upgrade has been completed, it's recommended to login to the backoffice to verify if your project is upgraded to new version.

  1. The following files/folders need to be copied from the Umbraco 8 project into the new project:

    • ~/Views - Do not overwrite the default Macro and Partial View Macro files unless changes have been made to these.

    • ~/Media - Media folder from v8 needs to be copied over into the wwwroot - media folder

The latest version of Umbraco is different from Umbraco 8 in many ways. With all the files and data migrated it is now time to rewrite and re-implement all custom code and templates.

One of the changes is how published content is rendered through Template files. Due to this, it will be necessary to update all the Template files (.cshtml) to reflect these changes.

Read more about these changes in the section of the Umbraco CMS documentation.

  • Template files need to inherit from Umbraco.Cms.Web.Common.Views.UmbracoViewPage<ContentModels.HomePage> instead of Umbraco.Web.Mvc.UmbracoViewPage<ContentModels.HomePage>

  • Template files need to use ContentModels = Umbraco.Cms.Web.Common.PublishedModels instead of ContentModels = Umbraco.Web.PublishedModels

Depending on the extent of the project and the amount of custom code and implementations, this step is going to require a lot of work.

Once the new project runs without errors on a local setup it is time to deploy the website to production.

This concludes this tutorial. Find related information and further reading in the section below.

  • , for the configuration of Umbraco 7 and 8

Any files/folders related to Stylesheets and JavaScript.

  • Migrate custom configuration from the Umbraco 8 configuration files (.config) into the appsettings.json file on the new project.

    • As of Umbraco version 9, the configuration no longer lives in the Web.Config file and has been replaced by the appsettings.json file. Learn more about this in the article.

  • , if relevant.

    • As of Umbraco Forms version 9, it is only possible to store Forms data in the database. If Umbraco Forms was used on the Umbraco 8 project, the files need to be migrated to the database.

  • Run the new project.

    • It will give you an error screen on the frontend as none of the Template files have been updated. Follow Step 3 to resolve the errors.

  • "ConnectionStrings": {
        "umbracoDbDSN": "Server=YourLocalSQLServerHere;Database=NameOfYourDatabaseHere;User Id=NameOfYourUserHere;Password=YourPasswordHere;TrustServerCertificate=True"
    }

    If you use Umbraco Forms, then on the clean installation of Umbraco, you will need to install Umbraco.Forms package as well.

    Video Tutorial

    The video below shows how to complete the upgrade on an Umbraco Cloud project. While the overall process is the same, you must update to the latest supported version on Cloud locally before continuing on Cloud.

    Learn more about supported versions in the article.

    Step 1: Content Migration

    If you use Umbraco Forms, make sure to have to True before step 1.

    You can also add the connection details if you spin up a clean installation.

    This is only content migration and the database will be migrated.

    You need to manually update the view files and custom code implementation. For more information, see Step 3 of this guide.

    Step 2: File Migration

    Step 3: Custom Code in the latest version

    Creating, Saving and Publishing Content Options

    Learn how to create, save, and publish content pages in the Umbraco backoffice, including scheduling and unpublishing options.

    In this article, you get an overview of how to create and save pages. You will also learn more about how to publish and unpublish your content.

    If you are a Cloud user, you will also learn how to compare and transfer content between environments. In Umbraco Cloud, an environment is a separate workspace such as Development, Staging, or Live/Production. It lets you preview and test changes before moving them to your live site. For more information about environments, see the Environments article in the Umbraco Cloud documentation.

    Creating a New Page

    Select the parent page to create your new page. The parent page can be the home page or any of the sub-pages of the site.

    If the parent page allows sub-pages underneath it, follow these steps:

    1. Hover over the name of the parent page in the Content section and click ••• to view the types of pages you can create.

    2. Select the page type you wish to create. The new page is loaded in the editor on the right-hand side.

    3. Enter a Name for the page and click Save.

    There are three different options for saving and publishing pages. The options vary depending on whether you’re still in the process of editing the page or you’re ready to publish your changes.

    The Save and preview button allows you to save your changes and preview it before publishing the changes to the live site. The Preview feature shows you how the page will look once it is published. This Save and preview feature only saves your page and does not publish your contents to the live site.

    The Save button is used for saving the page without publishing the changes to the live site. The Save feature prevents data loss during long-term projects. Use it frequently to protect your ongoing changes.

    The Save and publish button is used to publish a previously saved page to the live website or to publish a page without previewing it. The Save and publish feature will save and publish the page to your live website.

    The Save and publish button has three options:

    The Schedule button allows you to set a time and a date for when your page should be published. The Schedule option lets you keep editing your page. The site will automatically publish at your scheduled date and time.

    To set up scheduled publishing, follow these steps:

    1. Navigate to the page you want to publish.

    2. Select the arrow next to the Save and Publish button.

    3. Select Schedule publish.

    4. In the Scheduled Publishing window, set the date and time in the Publish at field.

    1. Select Schedule.

    The Publish with descendants button allows you to publish the current page and all the content linked to this page to the live site. Using this option, you can publish the current parent page and its child nodes, previously published, and unpublished content items.

    To publish the node with descendants, follow these steps:

    1. Navigate to the page you want to publish.

    2. Select the arrow next to the Save and Publish button.

    3. Select Publish with descendants.

    4. Toggle the option to Include unpublished content items if you wish to. This option includes all unpublished content items for the selected page and the descendant pages.

    The Unpublish button allows you to unpublish a page if you do not want a page to be publicly visible.

    To unpublish a page, follow these steps:

    1. Navigate to the page you want to unpublish.

    2. Select the arrow next to the Save and Publish button.

    3. Select Unpublish.

    Take note of any listed items with dependencies on the content your are unpublishing. This will typically be child items published under the content you have selected.

    You can also unpublish your page by setting the date and time using the Schedule feature.

    To set up scheduled unpublishing, follow these steps:

    1. Navigate to the page you want to unpublish.

    2. Select the arrow next to the Save and Publish button.

    3. Select Schedule.

    4. In the Scheduled Publishing window, set the date and time in the Unpublish at field.

    Migrate Content to Umbraco 15

    This article will help you migrate content to Umbraco 15, and outline options to skip this content migration

    The options in this article apply to the upgrade to Umbraco versions 15 to 17.

    Umbraco 18 doesn't include this content migration. Complete the upgrade to Umbraco 17 before you upgrade to Umbraco 18.

    Umbraco 15 changes the internal data format of all Block Editors.

    If you maintain a large Umbraco site with extensive Block Editor usage, the upgrade to Umbraco 15+ might require a long-running content migration. For the duration of the migration, your site will be unresponsive and unable to serve requests.

    You can track the progress of the migration in the logs.

    It is advised to clean up old content versions before upgrading. This will make the migration run faster.

    Parallelizing the content migration

    It is possible to parallelize the content migration. This will speed up the migration for large sites.

    For certain content structures, parallel content migration will fail. Therefore, parallel content migration is strictly opt-in.

    If parallel content migration fails, the database state will be rolled back to the last known good state. You can then disable parallel content migration, and try the migration again.

    To enable parallel content migration, add an IComposer implementation to configure the ConvertBlockEditorPropertiesOptions before initiating the upgrade process:

    It is strongly recommended to let the migration run as part of the upgrade. However, if you are upgrading to Umbraco versions 15, 16, or 17, you can opt out of the migration. Your site will continue to work, albeit with a certain degree of performance degradation.

    You can opt out of migrating each Block Editor type individually. To opt-out, add an IComposer implementation to configure the ConvertBlockEditorPropertiesOptions before initiating the upgrade process:

    Subsequently, you are responsible for performing the content migration yourself. This must be done before upgrading past Umbraco 17.

    Custom code is required to perform the content migration. You can find inspiration in the core migrations:

    • for Block List properties.

    • for Block Grid properties.

    • for Rich Text Editor properties.

    Running Umbraco in Docker Using Docker Compose

    Running Umbraco on docker locally using docker compose

    This article shows how to run Umbraco locally in Docker using Docker Compose. You can use either SQL Server or SQLite for development.

    Before you can run Umbraco in Docker, make sure the following are installed:

    • .NET SDK with Umbraco Templates v16 or higher

    • Docker Desktop

    To install Umbraco using the provided Dockerfile and Docker Compose setup, follow these steps:

    Finding Content

    The Umbraco content tree view allows you to navigate web pages through a logical site hierarchy. You can find a page by navigating through the tree itself if you know where the page is stored.

    To search across all the content, files, or folders in Umbraco, click the Magnifier icon in the top-right of the screen. Alternatively, you can use the keyboard shortcut CTRL + SPACE to access the Search bar.

    Using the search bar, you can enter a search term to search across most content and settings data in the backoffice. This includes:

    • Document Types

    • Data Types

    Opting out of the content migration

    Blocks in Rich Text Editors might not work as expected if you opt out of the content migration.

    This custom code should not run while editors are working in the Umbraco backoffice.

    The site may require a restart once the content migration is complete.

    ConvertBlockListEditorProperties
    ConvertBlockGridEditorProperties
    ConvertRichTextEditorProperties
    using Umbraco.Cms.Core.Composing;
    using Umbraco.Cms.Infrastructure.Migrations.Upgrade.V_15_0_0;
    
    namespace UmbracoDocs.Samples;
    
    public class DisableBlockEditorMigrationComposer : IComposer
    {
        [Obsolete]
        public void Compose(IUmbracoBuilder builder)
            => builder.Services.Configure<ConvertBlockEditorPropertiesOptions>(options =>
            {
                // setting this to true will parallelize the migration of all Block Editors
                options.ParallelizeMigration = true;
            });
    }
    DisableBlockEditorMigrationComposer.cs
    using Umbraco.Cms.Core.Composing;
    using Umbraco.Cms.Infrastructure.Migrations.Upgrade.V_15_0_0;
    
    namespace UmbracoDocs.Samples;
    
    public class DisableBlockEditorMigrationComposer : IComposer
    {
        [Obsolete]
        public void Compose(IUmbracoBuilder builder)
            => builder.Services.Configure<ConvertBlockEditorPropertiesOptions>(options =>
            {
                // setting this to true will skip the migration of all Block List properties
                options.SkipBlockListEditors = false;
    
                // setting this to true will skip the migration of all Block Grid properties
                options.SkipBlockGridEditors = false;
    
                // setting this to true will skip the migration of all Rich Text Editor properties
                options.SkipRichTextEditors = false;
            });
    }

    Create a folder and navigate into it:

    1. Create a new Umbraco project with Docker support:

    1. Add Docker Compose files:

    The -P flag is required to specify the correct paths in the docker-compose file. The project is now ready to run with Docker Compose.

    The folder structure should now look like this:

    • MyDockerProject/

      • Database/

        • Dockerfile

        • healthcheck.sh

        • setup.sql

        • startup.sh

      • MyDockerProject/

        • Your project files

        • Dockerfile

      • .env

      • docker-compose.yml

    The project now includes docker files for both Umbraco and the SQL server database.

    It also includes additional scripts to launch and configure the database and a .env file with the database password.

    1. Run the following command from the root folder (where docker-compose.yml is located):

    1. Access the site at http://localhost:44372.

    1. Create a new folder and navigate into it:

    1. Create a new Umbraco project:

    1. Add a Dockerfile

    1. Build the container:

    1. Run the container:

    1. Access the site at http://localhost:8080.

    There are some useful commands you can use to manage the docker containers:

    • docker compose down --volumes: Deletes containers and the volumes they use. This is useful if you want to start from scratch.

    • docker compose up --build: Rebuild the images and start the containers. This is useful if you have made changes to the project and want to see them reflected on the running site.

    • docker compose watch: Start the containers and watch the default models folder. This means that if the project uses a source-code models builder the images are automatically rebuilt and restarts when you change the models.

    The docker compose file uses bind mounts for the following folders:

    • /wwwroot/media

    • /wwwroot/scripts

    • /wwwroot/css

    • /Views

    • /models

    This is not meant to be used in production.

    For local development, however, this means that the files necessary for development are available from outside the container in your IDE. This allows development even though the project is running in docker.

    The umbraco-compose template supports:

    • -P or --project-name: The name of the project. This is required and used to set the correct paths in the docker-compose file.

    • -dbpw or --DatabasePassword: Used to specify the database password. This is stored in the .env file and defaults to: Password1234.

    • -p or --Port: Used to specify the port the site will run on. Defaults to 44372.

    This setup is intended for local development only. It is not recommended for production environments.

    Copying a Page

    Learn how to copy a page and its child pages to a different location in the content tree.

    Re-use a page or a tree structure you have previously created by copying the parent page and its child pages to a different section within the site structure.

    When you copy a parent page all of its child pages are also copied, by default. You can choose if you want to copy the child pages or not. You can also choose whether the links should be automatically updated or continue to link to the original pages.

    You can copy a page in two ways:

    Option 1

    1. Go to Content.

    2. Click ... next to the page you wish to copy.

    3. Select Duplicate to.

    A window appears on the right side of the screen. Here, you can choose where you want to copy the page in the tree structure.

    1. Toggle Relate to original button if you want to keep the links linked to the original page.

    2. Toggle Include descendants if you want to copy the child pages alongside the parent page.

    3. Click Copy.

    1. Go to Content.

    2. Select the page you wish to copy.

    3. Click ... next to the title of the page.

    4. Select Duplicate to.

    A window appears on the right side of the screen. Here, you can choose where you want to copy the page in the tree structure.

    1. Toggle Relate to original button if you want to keep the links linked to the original page.

    2. Toggle Include descendants if you want to copy the child pages alongside the parent page.

    3. Click Copy.

    Option 2

    When you select Relate to original, Umbraco will create a relationship between the original and copied page. This relationship can be used to programmatically link the pages - For example, linking two pages in a multilingual setup. This relationship does not sync the content between the original and copied page.

    Upgrade Unattended

    Learn how to enable unattended upgrades, allowing your project to upgrade without your interference.

    When upgrading your Umbraco project, you can enable the upgrade to run unattended. This means that you will not need to run through the installation wizard when upgrading.

    Are you running a load-balanced setup with multiple servers and environments?

    Check out the section about .

    Enable the unattended upgrade feature

    1. Add the Umbraco:Cms:Unattended:UpgradeUnattended configuration key.

    2. Set the value of the key to true.

    appsettings.json
    {
        "Umbraco": {
            "CMS": {
                "Unattended": {
                    "UpgradeUnattended": true
                }
            }
        }
    }

    Run the upgrade

    With the correct configuration applied, the project will be upgraded on the next boot.

    Boot order

    The behavior described below applies to Umbraco 17.3 and later. In earlier versions, migrations ran synchronously before the web server started accepting requests.

    When the application starts, migrations run in a background service after the web server begins listening. During the migration the RuntimeLevel is Upgrading. The web server is reachable during this time, serving health probe responses and maintenance pages.

    Once all migrations complete, the RuntimeLevel transitions to Run and the site operates normally.

    While the RuntimeLevel is Upgrading, Umbraco responds differently depending on the request surface:

    Surface
    Behavior

    The returns HTTP 200 during the upgrade, confirming the process is alive. The returns HTTP 503, indicating the site is not yet ready to serve normal traffic.

    You can customize the maintenance page shown to frontend visitors by setting the Umbraco:CMS:Global:UpgradingViewPath configuration key. See for details.

    Follow the steps outlined below to use unattended upgrades in a load-balanced setup.

    1. .

    2. Deploy to all environments.

    3. Set the Umbraco:CMS:Unattended:UpgradeUnattended configuration key to true for the Main server only.

    You can use the to let your load balancer detect when each server has completed its upgrade and is ready to receive traffic.

    Default Data/Media Types

    On this page you will find the media types and Data Types in Umbraco. These types are not created automatically after an upgrade. If you want to use the new types, you can create them yourself.

    After upgrading, the default media types are not created automatically. If you create them manually, make sure to:

    • Set the permission for each of the media types to Allow at root.

    • Ensure that the Folder media type allows the new media types as children.

    Migrate Custom Property Editors to Umbraco Version 14 and Later

    This article helps you migrate custom Property Editors to Umbraco 14 and later

    This article applies only to implementers of custom Property Editors, that is:

    • Maintainers of Property Editor packages.

    • Site implementers who have built their own Property Editors.

    Umbraco 14 introduces a split between server-side and client-side Property Editor aliases. The reasoning behind this change is two-fold:

    1. It allows server-side implementations to be reused for multiple client-side Property Editor UIs.

    2. It helps to ensure a better division between client-side and server-side responsibility.

    Migration impact for Property Editors

    In the Umbraco source code, the change manifests as the EditorUiAlias property on IDataType.

    When upgrading from Umbraco 13 to Umbraco 14 and later, Umbraco automatically migrates all Data Types to include an EditorUiAlias value. For custom Property Editors, this migration is based on certain assumptions.

    If the Property Editor is built with a :

    1. Assign the package manifest alias to the Data Type EditorUiAlias, and

    2. Convert the Data Type EditorAlias to the alias of a core Data Editor, based on the valueType specified in the package manifest.

    The following table contains the applied conversion from valueType to EditorAlias:

    If the Property Editor is built with a , we:

    1. Assign the Data Editor Alias to the Data Type EditorUiAlias, and

    2. Retain the Data Type EditorAlias as-is (which is the Data Editor Alias).

    The file is a central component for extensions in Umbraco 14+, including Property Editor UIs.

    To keep the Property Editor working with migrated properties, ensure that the propertyEditorUi extension is declared with:

    1. The migrated value of EditorUiAlias as its alias, and

    2. The migrated value of EditorAlias as its propertyEditorSchemaAlias (found in the extension meta collection).

    For example:

    If the Data Type migration yields an undesirable result, you have two options:

    1. Manually change the EditorAlias and/or EditorUiAlias directly in the umbracoDataType table, or

    2. Create a custom migration to update the properties. See the article for inspiration.

    Document Blueprints

    Learn how to create and use Document Blueprints in Umbraco.

    Manifest based Property Editors

    This might also impact Property Value Converters

    Property Value Converters for package manifest based Property Editors might be impacted by this migration.

    It is common practice to pair a Property Editor to a Property Value Converter using the package manifest alias:

    public bool IsConverter(IPublishedPropertyType propertyType)
      => propertyType.EditorAlias.Equals("My.Editor.Alias");

    Since the migration moves the alias to EditorUiAlias, the Umbraco 14 and later equivalent code looks like this:

    Code based editors

    The Data Editor Alias is found in the DataEditor attribute:

    [DataEditor("My.Editor.Alias")]
    public class MySuggestionsDataEditor : DataEditor
    {
    }

    Migration impact for porting Property Editor UIs

    Additional Options and Troubleshooting

    Troubleshooting: Templates fail to install

    In some cases, the templates may silently fail to install (usually this is an issue with NuGet sources). If this occurs, specify the NuGet source directly:

    Verify the templates were installed

    Run dotnet new list to confirm that Umbraco was added to the list of available project types:

    Full list of template options

    Run dotnet new umbraco -h to see all available options:

    Sorting Pages

    Learn how to change the sort order of pages within the content tree using the Sort function.

    The pages in Umbraco are placed in the tree structure according to a predefined sort order. The most recently created page is placed at the bottom of the tree structure. You can change the order of the pages by using the Sort function.

    You can sort pages in two ways:

    Option 1

    1. Go to Content.

    2. Navigate to the parent node whose child nodes you wish to sort.

    3. Click ... next to the page you wish to sort.

    Data Types

    Learn about the data types in Umbraco.

    A Data Type defines the type of input for a property. So when adding a property (on Document Types, Media Types and Members) and selecting the Type you are selecting a Data Type. There are preconfigured Data Types available in Umbraco and more can be added in the Settings section.

    A Data Type can be something basic such as TextString, Number, True/False and so on. Or it can be more complex such as Multi Node Tree Picker, Image Cropper, Block Grid and so on.

    The Data Type references a Property Editor and if the Property Editor has settings these are configured on the Data Type. This means you can have multiple Data Types referencing the same Property Editor.

    An example of this could be to have two dropdown Data Types both referencing the same dropdown Property Editor. One configured to show a list of cities, the other a list of countries.

    Follow these steps to create a new Dropdown Data Type:

    1. Go to the Settings section within the backoffice.

    Upgrade to Umbraco 7

    This document should be used as a reference, not a step by step guide. Upgrading will largely depend on what version of Umbraco you are currently running, what packages you have installed and the many

    The standard upgrade instructions still apply to this process as well.

    Backup

    It is critical that you back up your website and database before upgrading. There are database changes made during installation and you cannot revert an Umbraco 7 database to an Umbraco 6 database.

    .Net 4.5

    Umbraco 7 is built on .Net 4.5 and your development environment will require this version installed in order to operate. Visual Studio users may require 2012 or higher.

    HTML 5 browser support

    Umbraco 7 requires browsers with proper HTML 5 support, these include Chrome, Firefox, IE10+

    Breaking changes

    Before you upgrade be sure to read the list of breaking changes. This is especially recommended if you have removed or modified code in the core or if one of these breaking changes directly affects your installation.

    See the list of breaking changes for more details.

    Examine

    It is recommended to rebuild all Examine indexes after completing the upgrade.

    Xml Cache rebuild

    You should re-generate the XML cache. This can be done by following the prompts when visiting the following URL:

    your-domain.com/umbraco/dialogs/republish.aspx?xml=true

    It is recommended that you use a Diff tool to compare the configuration file changes with your own current configuration files.

    • /web.config updates

      • Details are listed here:

      • You will need to compare the new Umbraco 7 web.config with your current web.config. Here is a quick reference of what needs to change:

    Umbraco 7+ will no longer support medium trust environments. There are now some assemblies used in the core that do not support medium trust but are used extensively. Plugin scanning now also allows for scanning Umbraco's internal types which requires full trust.

    Content, Media, Members, and Data Type trees will no longer raise the legacy tree events (based on BaseTree). It is recommended to change all tree event handlers to use the new tree events that fire for every tree in Umbraco including legacy trees. The new tree events are static events and are found in the class Umbraco.Web.Trees.TreeControllerBase:

    • MenuRendering

    • RootNodeRendering

    • TreeNodesRendering

    The Content, Media, Member, and Data Type editors have been re-created and are solely using the new Umbraco Services data layer. This means that operations performed in the backoffice will no longer raise the legacy business logic events (for example, events based on umbraco.cms.businesslogic.web.Document). It is recommended to change your event handlers to subscribe to the new Services data layer events. These are static events and are found in the services. For example: Umbraco.Core.Services.ContentService.Saved.

    Legacy property editors (pre-Umbraco 7) will not work with Umbraco 7. During the upgrade installation process, Umbraco will generate a report showing you which legacy property editors are installed. These will all be converted to a readonly Label property editor. No data loss will occur but you'll need to re-assign your existing data types to use a new compatible Umbraco 7 property editor.

    Most Umbraco core property editors shipped will be mapped to their equivalent Umbraco 7 editors. The Image cropper editor has not been completed for v7.0.

    Since the Related Links property is an advanced property editor, the data format has changed from XML to JSON. This should not have any effect when retrieving the data from razor. If you are outputting Related Links data with XSLT you will need to update your XSLT snippet. Making use of the new library method umbraco.library:JsonToXml and taking into account that the xml structure has also slightly changed.

    One of the database changes made in Umbraco 7 is the change of referencing a property editor from a GUID to a string alias. In order to map a legacy property editor to a new Umbraco 7 version you can add your custom "GUID -> Alias" map during application startup. To do this you would add your map using this method: Umbraco.Core.PropertyEditors.LegacyPropertyEditorIdToAliasConverter.CreateMap

    Legacy parameter editors (pre-Umbraco 7) will not work with Umbraco 7. If Umbraco detects legacy parameter editor aliases that do not map to a Umbraco 7 parameter editor it will render a textbox in its place. You will need to update your macros to use a compatible Umbraco 7 parameter editor as those that aren't supported.

    Previously, parameter editors were registered in an Umbraco database table: cmsMacroPropertyType which no longer exists. Parameter editors in Umbraco 7 are plugins like property editors. During the Umbraco 7 upgrade installation process it will update the new cmsMacroProperty.editorAlias column with the previous parameter editor alias. During this process it will look into the Umbraco.Core.PropertyEditors.LegacyParameterEditorAliasConverter for a map between a legacy alias to a new Umbraco 7 alias.

    Custom legacy parameters can be mapped to new Umbraco 7 parameter editor aliases during installation. This can be done by modifying the mapping during application startup using this method: Umbraco.Core.PropertyEditors.LegacyParameterEditorAliasConverter.CreateMap.

    All database changes will be taken care of during the upgrade installation process.

    For database change details see (including all child tasks):

    See above for the database updates made for better tag support.

    • Tags can now be assigned to a nodes property and not only a node

    • Multiple tag controls can exist on one page with different data

      • The legacy API does not support this, the legacy API will effectively, add/update/remove tags for the first property found for the document that is assigned a tag property editor.

    • There is a new ITagService that can be used to query tags

    You should check with the package creator for all installed packages to ensure they are compatible with Umbraco 7.

    We see common errors that we cannot fix for you, but we do have recommendations you can follow to fix them:

    The TypeFinder has been deprecated since 4.10 and is now found under Umbraco.Core.TypeFinder.

    While you need to have JavaScript inside menu actions to trigger a response, it is highly recommended that you use the recommended UmbClientMgr methods. You should not try to override parent.right.document and similar tricks to get to the right-hand frame.

    If you have a webforms page, it is recommended to use the built-in ASP.NET controls to render panels, properties and so on. If you use the raw HTML or try to style it to match the backoffice, you will get out of sync. Follow the guidelines set by Umbraco's internal editors and use the ASP.NET custom controls for UI.

    Preview Pane Responsive View

    When viewing page content in preview mode you have the option to scale the preview window to various device sizes:

    1. Once you have finished editing the page content, click Save and preview.

    2. Select Fit browser to view the different preview modes.

    3. Select the device you would like to scale the preview pane to.

    Sidebar

    This section explains how the concept of infinite editing using the Sidebar in the Umbraco backoffice works.

    This feature enables you to work with your content without losing the context of what you are doing.

    Document Types are in different sections than content but the sidebar enables you to make changes to them directly from the content you are editing.

    Sidebar

    In the example showcased above, new options are being added to a Data Type, without losing the context of the content. The example also shows how you can edit images, without being sent to the 'Media' section.

    Customize

    The Sidebar can be customized to improve the workflow for editors. For more information, see the Extending Overview article.

    Running Umbraco on Linux/macOS

    Since Umbraco 9 it has been possible to run Umbraco CMS natively on Linux or macOS High Sierra 10.13 and newer.

    With Umbraco CMS on .NET Core, Linux and macOS is natively supported with SQLite as the database.

    In the below section, we describe how to get started with running Umbraco CMS on Linux or macOS.

    How to get started running Umbraco CMS on Linux or macOS

    To get started with Umbraco CMS first have a look at the .

    Once you've made sure you meet the requirements it is time to install the Umbraco Templates on your system.

    To do this follow the guide.

    With the templates installed on your system, it is now possible to create Umbraco projects.

    To create a project, there are two options:

    • Continue creating projects using the .NET CLI.

    • Create new projects using Visual Studio (only macOS).

    To create new projects using Visual Studio, you can use the guide.

    Once you create a new project it will use SQLite by default on Linux/macOS.

    If you prefer using SQL Server as your database, you can either install it locally or run it via .

    After logging in to an Umbraco project you will be presented with a dashboard containing a wide array of buttons and features. Let's quickly go through what each feature does.

    By default, there are two dashboards available:

    1. The Welcome to Umbraco dashboard provides helpful information about Umbraco.

    2. The Redirect URL Management dashboard displays the original and redirected links of the published pages which are moved to a new location in your project.

    Email Address

    In this article you can learn how to use the build in email property editor

    Schema Alias: Umbraco.EmailAddress

    UI Alias: Umb.PropertyEditorUi.EmailAddress

    Returns: String

    Displays an email address.

    The Email Address Property Editor does not come with any further configuration. The property can be configured once it has been added to a Document Type.

    See the example below to learn how a value can be added or changed programmatically to an Email-address property. To update a value of a property editor you need the .

    Using Tabs

    In this section, an overview is given of how to add and reorder tabs, convert a group to a tab and manage the “Generic” tab.

    Using tabs, you can organize properties in the backoffice to provide a tailored and efficient workflow for editors creating and maintaining Content, Media and Members.

    Tabs allow you to add horizontal organization in your Document Types, Media Types and Member Types. This is handy for types that need a more defined hierarchy or have many properties and groups.

    To add a tab, follow these steps:

    1. Go to Settings.

    2. Create or select a Document Type/Media Type/Member Type

    Data

    This section focuses on how to create data using the Umbraco backoffice

    There are four kinds of content in Umbraco:

    • The website content that make our the pages on your site exists in the Content section.

    • Elements are reusable content items that are managed from the Library section.

    • Media content such as images, videos, and PDFs are stored in the Media section.

    Audit Trail

    Learn how to use the Audit Trail to view the history of actions performed on a content page.

    Within the Info content app for pages you can find the Audit Trail in the History section. Here, you can get a quick overview of the actions performed on that node, by whom, when and any additional comments.

    The Audit Trail is useful to find out who made changes on a certain date.

    To view the audit trail:

    1. Go to the Content section.

    The address at which you access Umbraco may vary so check with your system administrator.

    Logging Out

    Login Screen
    Logout Screen
    Navigate to the page you wish to see the audit trail.
  • Go to the Info Workspace View.

  • Locate the History box.

  • Audit Trail

    Session Timeout

    Umbraco is set up to automatically log a user out if they have been inactive for over 20 minutes. Don't worry if you are logged out of Umbraco. Log back in using your credentials and continue editing.

    Session Timeout Configuration for Developers

    The session timeout can be configured in Umbraco's appsettings.json file. You can modify the Timeout setting to extend or reduce the timeout duration based on your site's needs.

    Add value programmatically

    The example below demonstrates how to add values programmatically using a Razor view. However, this is used for illustrative purposes only and is not the recommended method for production environments.

    The value sent to an EmailAddress property needs to be a correct email address, For example: [email protected].

    It is recommended that you set up validation on this property, in order to verify whether the value added is in the correct format.

    Content Service
    Checkbox Example
    Single email address content example
    @if (Model.HasValue("email"))
    {
        var emailAddress = Model.Value<string>("email");
        <p>@emailAddress</p>
    }
    @if (!string.IsNullOrWhiteSpace(Model.Email))
    {
        <p>@Model.Email</p>
    }
    @using Umbraco.Cms.Core.Services;
    
    @inject IContentService Services;
    @{
        // Get access to ContentService
        var contentService = Services;
    
        // Create a variable for the GUID of your page
        var guid = new Guid("796a8d5c-b7bb-46d9-bc57-ab834d0d1248");
    
        // Get the page using the GUID you've just defined
        var content = contentService.GetById(guid);
        // Set the value of the property with alias 'email'
        content.SetValue("email", "[email protected]");
    
        // Save the change
        contentService.Save(content);

    To reorder tabs, follow these steps:

    1. Go to Settings.

    2. Select a Document Type/Media Type/Member Type.

    3. Select Reorder.

    You can drag the tab where you want, manually add a numeric value next to the tab name or use the arrows to set a value.

    This is important when using compositions, as you want to always display a tab/group at a certain position by setting a manual numeric value.

    Reorder tabs
    1. Select I am done reordering.

    2. Click Save.

    To convert a group to a tab, follow these steps:

    1. Go to Settings.

    2. Select a Document Type/Media Type/Member Type.

    3. Select Reorder.

    4. You can drag the group to the Convert to tab option.

    5. Select I am done reordering.

    6. Click Save.

    Once you start adding tabs, you might see a “Generic” tab appear. This is done to hold groups and properties that are not assigned to a tab. For example, a group of properties coming from a composition that has no tab. In order to display the groups and properties correctly and have a solid data structure, they will be displayed under the “Generic” tab.

    Generic-tab

    To manage the Generic tab on a Document Type/Media Type:

    1. Go to the Composition Document Type/Media Type.

    2. Click Add tab and enter the Name for the tab. All existing groups and properties are added to the tab.

    3. Go to the Document Type/Media Type, the Generic tab will now be replaced by the tab from the composition.

    Composition Add Tab

    Adding a tab

    When adding the first tab, all existing groups are automatically added to the tab.

    Reordering tabs

    Convert a group to a tab

    Converting a tab back into a group is not possible, as tabs can contain groups, and nested groups are unsupported. To overcome this, create a new group and transfer all tab properties into it, then delete the empty tab.

    Managing the “Generic” tab

    Finally, Members, are used for user profiles and frontend authentication which you can find in the Members section.

    A fundamental principle in Umbraco is that all content types have a definition (Document Types, Media Types, Member Types). These definitions are highly customizable, meaning you can add properties and have complete control over how the data is organized.

    Defining Document Types, adding properties, and creating content.

    Defining Media Types and uploading files to the media section, using upload fields and image cropper.

    Defining Member Types and creating members for authentication and user profiles.

    Content Within the Tree View

    When you are looking to edit content, locate the page you want to edit in the Content tree on the left-side of the screen.

    Viewing Pages in Content Section

    To edit existing content, follow these steps:

    1. Go to the Content section.

    2. Select the page in the section tree you wish to edit. The content of the page is loaded in the right-side editor.

    3. Edit the contents of the page.

    4. Click Save to save the edits without publishing it.

    5. Click Save and preview to preview the changes.

    6. Click Save and publish to publish the changes. For more information, see the article.

    By default, you can view Page layouts in two ways: in a List or in a Grid (default).

    When you enable Collection on a page, its child pages are no longer shown as nested items in the content tree. Instead, the parent page appears as a single node in the tree. Selecting it displays all of its child pages in a grid view within the main workspace area. For more information, see the article.

    You can switch to a list view by clicking the layout icon in the top-right of the screen:

    Property Editors

    Overview of Property Editors in Umbraco, how they work, the built-in editors available, and how to create custom ones.

    A Property Editor is what content editors use to input data on a Document Type. When you create a Data Type in the backoffice, you choose a Property Editor and configure it. Umbraco ships with a wide range of built-in Property Editors, and you can create custom ones.

    Are you looking for the Grid Layout or Nested Content?

    These Property Editors were removed in Umbraco version 14:

    • Grid Layout

    • Nested content

    Time Only

    Schema Alias: Umbraco.TimeOnly

    UI Alias: Umb.PropertyEditorUi.TimeOnlyPicker

    Returns: TimeOnly?

    The Time Only property editor provides an interface for selecting times. It excludes date and time zone information, and returns strongly-typed TimeOnly values.

    You can configure this property editor in the same way as any standard property editor, using the Data Types admin interface.

    To set up a property using this editor, create a new Data Type and select Time Only from the list of available property editors.

    Downgrades and Re-Running Migrations

    Discusses the possibility of downgrading to a previous version, along with the related topic of re-running the migrations that have occurred during an upgrade

    Downgrades are not a supported feature of the Umbraco product.

    The primary reason for this is that the Umbraco migration scheme only supports upward migrations.

    When updating to a new version, often there are migrations to run that will make changes to the Umbraco schema and data. This is being done to bring the database to a state that will support the functionality of the version being upgraded to.

    There isn't an equivalent downward migration that will undo these changes.

    Given that, it can't be guaranteed that a database from a later version will work with an earlier one.

    If you wish to downgrade to an earlier version of Umbraco, it's best to also revert to a compatible database backup. You will need one from the version you are downgrading to.

    Other factors that may preclude downgrading include packages you may be using. They may not be compatible with the lower version or support downgrades themselves.

    That said, between some versions, a downgrade may be possible and perfectly safe. There may be no migrations that run between them. Or, as is often the case, migrations are backward compatible (for example, adding a new, nullable field to a database table).

    Relations

    Learn about relations and how to create and manage them.

    Umbraco sections are built around the concept of 'trees' and there is an implicit relationship between items in a section tree.

    We refer to these relationships in the manner of a 'Family Tree'. One content item might be the 'Parent' of some content items, and those items would be referred to as the 'Children' of that parent. Items within the same branch of the tree can also be described as 'Ancestors' or 'Descendants' of an item.

    There are methods available to support querying content items by their relative position to the current page. This is possible using the following concepts: Model.Ancestors(), Model.Children(), or Model.Descendants().

    In some cases there are no direct relationships between two items in a tree, but they are still somehow 'related'. This could be the alternate language translation pages of a content page.

    In other cases there is a 'relation' between different types of entities. This could be a relation between Content and Member, or Member and MediaFolder. You might need to be able to retrieve and display the uploaded images from a specific logged-in Member.

    Member Group Picker

    Schema Alias: Umbraco.MemberGroupPicker

    UI Alias: Umb.PropertyEditorUi.MemberGroupPicker

    Returns: string

    The Member Group Picker opens a panel to pick one or more member groups from the Member section. The value saved is of type string (comma separated IDs).

    See the example below to see how a value can be added or changed programmatically. To update a value of a property editor you need the .

    You can also add multiple groups by creating a comma separated string with the desired member group IDs.

    Block Level Variance

    An intro to achieving content variance at block level.

    In a variant context, a Block Editor behaves like any other Umbraco property editor by default. The Blocks contained within the editor "belong" to the Document variant, and there is no connection between Blocks across variants.

    In other words, both Block content and structure can vary between each Document variant.

    This is the desired behavior for many cases. However, in some cases it is preferable to have a shared Block structure across all variants, where only the Block content varies.

    This is known as Block Level Variance:

    Block Level Variance is achieved when:

    Element Picker

    Learn how to configure and use the Element Picker property editor in Umbraco CMS.

    Schema Alias: Umbraco.ElementPicker

    UI Alias: Umb.PropertyEditorUi.ElementPicker

    Returns: IEnumerable<IPublishedElement>

    The Element Picker enables you to choose one or more elements to display as part of your content. Elements are based on defined in the Settings section. They are created and managed in the Library section.

    Define how many elements should be allowed to pick via the Element Picker.

    Choose a start node for the Element Picker. Use this option when your Library section is organized into folders.

    Content Types and Structure

    Learn how to define and structure content in Umbraco using Document Types, Media Types, Data Types, compositions, and relations.

    In Umbraco, all content is defined by a type. Document Types define the fields on a page, Media Types define the properties of media items, and Member Types define user profiles. This section covers how to create and configure these content types and how to build structure through compositions and relations.

    • - key backoffice concepts: sections, trees, Document Types, Media Types, Data Types, and Property Editors.

    • - define Document Types, create Media Types, configure Data Types, and manage content in the backoffice.

    You will need to determine this for yourself, likely via reviewing the changes and migrations between versions and testing.

    Once you have done that, this article will explain how to proceed with downgrading.

    Downgrading the Umbraco application itself is straightforward. In the same way as when upgrading, you update the dependency on Umbraco in your project, you do the same when downgrading:

    dotnet add package Umbraco.Cms --version <VERSION>

    If you try to start Umbraco, it's likely you will find an exception thrown on boot indicating a problem with the migration state. This is because the version of Umbraco you are running now doesn't recognize the state stored by the higher version you were running previously.

    To resolve this, you need to query the Umbraco database.

    There are two migration states stored for the CMS - for the core migrations and the pre-migrations (which run at different times on start-up).

    You can find the current state of these via:

    You then need to find the latest state for the version of Umbraco you want to downgrade to.

    To find the earlier states you have to look in the source code, specifically here for the pre-migrations and here for the core ones.

    Each migration is commented with the version it was added, so you can read off the latest one for the version you wish to run.

    Having found the state you need, you set it via a query of the form:

    Then restart Umbraco.

    A related topic is if you want to re-run the migrations from a prior version to the version you are on.

    This isn't something that should be needed in normal usage of Umbraco. Umbraco handles running the necessary migrations on start-up and keeps track of its state. However, if investigating an upgrade-related issue or testing an upgrade before running it in production, it's useful to know how to do this.

    Again you need to manipulate the migration state stored in the database.

    You can update these values to an earlier state, and on start-up Umbraco will recognize that it's not at the latest. It will re-run the migrations from the earlier state to the current one.

    For example, you are running 18.1 and want to re-run the core migrations for 18. Set the core migration state to the latest one from Umbraco 17:

    And then restart Umbraco.

    Migrations are written to be idempotent, so they can be run multiple times. If the change the migration is making is already detected to be there, it should skip without throwing an exception.

    Downgrades are not strictly supported

    Particular downgrades are possible and safe

    • HH:mm - Displays hours and minutes (e.g., 14:30). Suitable for most general use cases.

    • HH🇲🇲ss - Displays hours, minutes, and seconds (e.g., 14:30:45). Use this when you need more precise timing.

    You will be presented with a time input. Unlike date-time editors, this editor focuses only on the time component.

    Time Only property editor interface

    The value returned will have the type TimeOnly?.

    With Models Builder:

    Without Models Builder:

    This property editor stores values as a JSON object. The object contains the time as an ISO 8601 string with a default date and UTC offset.

    The property editor stores values in this JSON format:

    The property editor handles time-only values. Date is set to a default value (0001-01-01) and offset to +00:00 for storage consistency. The date component is ignored in the Time Only context.

    1. Create a C# model that matches the JSON schema.

      using System.Text.Json.Serialization;
      
      namespace UmbracoProject;
      
      public class TimeOnlyValue
      {
          /// <summary>
          /// The time value, represented as a <see cref="DateTimeOffset"/> for storage compatibility.
          /// </summary>
          [JsonPropertyName("date")]
          public DateTimeOffset Date { get; init; }
      }
    2. Convert your existing time value to DateTimeOffset for storage.

      If you have a TimeOnly:

      TimeOnly timeOnly = TimeOnly.FromDateTime(DateTime.Now); // Your existing TimeOnly value
      DateTimeOffset dateTimeOffset = new DateTimeOffset(DateOnly.MinValue, timeOnly, TimeSpan.Zero);

      If you have a DateTime:

      DateTime dateTime = DateTime.Now; // Your existing DateTime value
      TimeOnly timeOnly = TimeOnly.FromDateTime(dateTime);
      DateTimeOffset dateTimeOffset = new DateTimeOffset(DateOnly.MinValue, timeOnly, TimeSpan.Zero);
    3. Create an instance of the class with the DateTimeOffset value.

    4. Inject the IJsonSerializer and use it to serialize the object.

    5. Inject the IContentService to retrieve and update the value of a property of the desired content item.

    These are the scenarios where the concept of Umbraco Relations provides a solution.

    Umbraco Relations allow you to relate almost any object in Umbraco to almost any other Umbraco object. This is done by defining a new Relation Type.

    With a Content, Member, or Media picker the relationship only works as a 1-way street. The content item knows it has 'picked' another content item but that other content item does not know where it has been picked.

    Umbraco Relations works as a 2-way street. When creating a relation between two different types of entities, it will be possible to find one entity from the other and vice versa. As an example this provides the option to list out all the pages that a content banner had been picked on.

    A Relation Type specifies how two types of entities are related. Two items might be related under multiple Relation Types, and you might only be interested in your 'Related Language Page' Relation Type.

    It is possible to view the existing Relation Types from the Umbraco backoffice:

    1. Access the Umbraco Backoffice.

    2. Navigate to the Settings section.

    3. Locate the Advanced group in the sidebar.

    4. Select Relations.

    View Relations

    On the dashboard all defined relations will be listed. Select a Relation to view a list of all the objects that have been related for that specific Relation Type.

    You can create Relations using the RelationService API via code.

    Some examples are provided here in the RelationService Documentation Page

    You might want to create a 'Relation' between two objects either as:

    • A response to a backoffice event. For example, a content item being published that has picked other content items. Storing a relationship between these items would make querying between them easier. Perhaps show all the pages on which a particular 'banner' has been picked.

    • A logged-in member on the front end of an Umbraco website might have the facility to upload images. In response, the implementation could store the photos programmatically in the Media Section and at the same time, create a Relation to record the relationship between the member and their uploaded pictures. On an image gallery page, it would be possible to display all the gallery images for the current logged-in Member using the relations.

    Some of the community packages that use Relations are listed below:

    • 'Relations Picker' - a content picker that automatically creates Relations.

    • 'ContentRelations' - allows you to relate two items via the Backoffice.

    • 'LinkedPages' - Provides a LinkedPages context item to show, edit, and add relations between content pages.

    is configured for variance, and
  • The Block Editor property is not configured for variance, and

  • The Block Editor property editor is configured to use Element Types that do vary.

  • When adding a new variant Block to one Document variant, it is automatically added to all variants of the Document.

    The Block will start out in an "unexposed" state for all other Document variants than the one where it was added. It will remain like that for each variant until it is edited in that variant.

    The "unexposed" state is visualized by a dimmed-down icon and title (or likely a missing title, if Umbraco Flavored Markdown is used):

    Block Level Variance in the backoffice - with an unexposed block

    It is entirely possible to mix and match variance and invariance within the scope of Block Level Variance. Invariance is fully supported, both at Block level and at Block property level.

    Invariance within Block Level Variance follows the same rules as invariance at Document level:

    • Invariant content is added to and updated across all Document variants.

    • Invariant content is explicitly published for all published Document variants when one or more variants are published.

    Consider a Document with English and Danish language variants, which is published in both languages.

    • An editor opens the English variant.

    • They add an invariant Block, and

    • They re-publish the English variant.

    Result: The new block will appear in both the English and Danish published content.

    • An editor opens the Danish variant.

    • They update an invariant property value in a variant Block, and

    • They re-publish the Danish variant.

    Result: The updated property value appears in both the English and Danish published content.

    The Block Editor structure is invariant for Block Level Variance. This means that the structure follows the same rules for invariance as outlined in the section above.

    In other words: If an editor changes the order of the Blocks in one Document variant, it changes for all Document variants. The change is applied to all published Document variants, as soon as one or more variants are published.

    Document Type Localization

    Setup localization for Document Types in the Umbraco backoffice.

    The Umbraco backoffice is localized to match the user's configured UI Culture.

    When defining a Document Type, you can apply localization to:

    • Document Type names and descriptions.

    • Property names and descriptions.

    • Custom property validation messages.

    • Tab and group names.

    Setting up localization for Document Types is a three-step process:

    • Register the Document Type localization files via .

    • Create the localizations in .

    • Apply the localizations to the Document Type.

    To register Document Type localizations, you must create a new manifest using an umbraco-package.json file.

    Once you have registered the Document Type localization, you can add your localization texts for use in Document Types. The following localizations are used for the samples in this article:

    The localizations are applied by using the syntax #{area alias}_{key alias}.

    1. Create a Document Type with Template called #contentTypes_article with the alias: articlePage.

    2. Under the newly created Document Type, follow these steps:

      • Set the description to #contentTypes_article_desc

    1. Add a property called #properties_subTitle with alias subTitle.

      • Set the description to {#properties_subTitle_desc}.

      • Use a TextString

    When creating and editing the content, you will see that the backoffice now uses the configured localizations.

    1. Create a new "Article" node:

    1. When trying to save the node without adding the mandatory content, you will see a warning as expected:

    The Code Editor property editor provides an interface for entering and editing code snippets. It offers features like syntax highlighting, line numbering, wrapping code and so on.

    Data Type Definition Example

    Code Editor definition example

    Configuration

    The Code Editor can be configured with the following settings:

    • Language: A dropdown to select the syntax highlighting and validation rules for the editor. Supported languages include C#, CSS, HTML, JavaScript, JSON, Markdown, Razor (CSHTML), and TypeScript.

    • Height: Allows you to specify the height of the editor in pixels (for example., 400px). This ensures the editor fits well within your content entry forms.

    • Line Numbers: A toggle to enable or disable the line number on the left side of the editor.

    • Minimap: A toggle to enable a high-level, zoomed-out visual overview of the code on the right side of the editor for faster navigation in long files.

    • Word Wrap: A toggle that determines if long lines of code should wrap to the next line or require horizontal scrolling.

    See the example below to see how a value can be added or changed programmatically. To update a value of a property editor you need the .

    Although the use of a GUID is preferable, you can also use the numeric ID to get the page:

    Checkbox List

    Schema Alias: Umbraco.CheckBoxList

    UI Alias: Umb.PropertyEditorUi.CheckBoxList

    Returns: IEnumerable<string>

    Displays a list of preset values as a list of checkbox controls. The text saved is an IEnumerable collection of the text values.

    Unlike other property editors, the Option IDs are not directly accessible in Razor.

    Data Type Definition Example

    True/Checkbox List Definition

    You can use dictionary items to translate the options in a Checkbox List property editor in a multilingual setup. For more details, see the article.

        }
    }

    Add values programmatically

    See the example below to see how a value can be added or changed programmatically. To update a value of a property editor you need the Content Service.

    The example below demonstrates how to add values programmatically using a Razor view. However, this is used for illustrative purposes only and is not the recommended method for production environments.

    @using Umbraco.Cms.Core.Serialization
    @using Umbraco.Cms.Core.Services
    @inject IContentService ContentService
    @inject IJsonSerializer Serializer
    @{
        // Create a variable for the GUID of the page you want to update
        var guid = Guid.Parse("32e60db4-1283-4caa-9645-f2153f9888ef");
    
        // Get the page using the GUID you've defined
        var content = ContentService.GetById(guid); // ID of your page
    
        // Set the value of the property with alias 'superHeroes'.
        content.SetValue("superHeroes", Serializer.Serialize(new[] { "Umbraco", "CodeGarden"}));
    
        // Save the change
        ContentService.Save(content);
    }

    Although the use of a GUID is preferable, you can also use the numeric ID to get the page:

    @{
        // Get the page using it's id
        var content = ContentService.GetById(1234);
    }

    If Models Builder is enabled you can get the alias of the desired property without using a magic string:

    Single Block Migration for Umbraco 18

    Learn how to migrate Block List property editors configured in single mode to the new Single Block property editor.

    Version 17 introduced the single block property editor. Its purpose is to replace the "single mode" option that exists in the Block List property editor. This is part of the broader effort to ensure type consistency across core property editors.

    Included migration

    Umbraco ships with a migration to:

    • Update all block list Data Types that have been properly configured in "single" mode.

    • Update all (nested) property data that uses this Data Type.

    The migration was added in Umbraco 17 but disabled. It now runs by default during the upgrade to Umbraco 18.

    Pre-running the migration

    You can run the migration at any time by using your own migration plan, as shown in the example below. If you run this migration yourself, the default Umbraco migration won't update any data. It only changes data in the old format.

    If your non-core property editor nests content and stores it within its own value, you must extend the migration. To do this, create and register a class that implements ITypedSingleBlockListProcessor and register it. See how the built-in types are registered at Umbraco.Cms.Infrastructure.Migrations.Upgrade.V_18_0_0.SingleBlockList.MigrateSingleBlockListComposer. The interface needs the following properties and methods:

    • IEnumerable<string> PropertyEditorAliases: The alias of the property editor as defined in its DataEditor attribute. Since a processor can support multiple editors if they use the same model, it takes an IEnumerable rather than a single string. These aliases are used to limit the amount of data fetched from the database.

    • Type PropertyEditorValueType: The type of value the property editor would return when valueEditor.ToEditor() is called.

    • Func<object?, Func<object?, bool>, Func<BlockListValue, object>, bool> Process

    Language Variants

    Learn how to use language variants to output your content in multiple languages.

    Language Variants allows you to vary content by culture, so you can allow a content node to exist in multiple languages.

    This article will cover the different aspects of enabling and working with language variants on your Umbraco website.

    Contents

    • Video tutorial

    • How to enable Language Variants

    To work with Language Variants you need to have more than one language enabled. This can be done from the Settings section:

    Now that there are two languages to vary the content with, it needs to be enabled on the Document Types. To do so:

    1. Go to the Document Type in the structure section.

    2. Open the settings page.

    3. Toggle Allow vary by culture.

    All new properties on a Document Type were Allow vary by culture is enabled, will inherit the ability to be varied by culture.

    It is also possible to make the properties shared across cultures. This means that the value added to the default language, will also be applied to all other languages.

    Set up property sharing, by enabling Shared across cultures in the Variation group when defining your properties:

    When you return to your content node you will notice two things:

    1. At the top of the Content tree there will now be a dropdown so you can show the Content tree in the language of your choice.

    2. To the right of the content name there is now a dropdown where you can select a language. You can also open a split view so you can see two languages at once.

    To read about how you render variant content in Templates, check out the .

    Culture and hostnames must be added to your language sites before the content can be tested for variants:

    1. Click ... next to the Home node and select Culture and Hostnames.

    2. Add a specific URL per language and save. For eg: An English language variant with English (United States) as the language can be given a specific URL https://yourwebsite.com/en-us and a Danish language variant can be given a specific URL https://yourwebsite.com/dk.

    The Info content app should now show specific URLs for your language variants.

    When you are working with a multilingual site you might want to control who can edit the different variations of the content on the website.

    This can be controlled on a User Group level. All default User Groups, except the Sensitive data group, have access to all languages out of the box.

    When "Allow access to all languages" is not checked, languages can be added and/or removed. This is to determine which variants the users in the user group have access to.

    Eye Dropper Color Picker

    Schema Alias: Umbraco.ColorPicker.EyeDropper

    UI Alias: Umb.PropertyEditorUi.EyeDropper

    Returns: string

    The Eye Dropper Color picker allows you to choose a color from the full color spectrum using HEX and RGBA.

    See the example below to see how a value can be added or changed programmatically. To update a value of a property editor you need the .

    Although the use of a GUID is preferable, you can also use the numeric ID to get the page:

    Entity Data Picker

    Schema Alias: Umbraco.EntityDataPicker

    UI Alias: Umb.PropertyEditorUi.EntityDataPicker

    Returns: Umbraco.Cms.Core.Models.EntityDataPickerValue

    Supported Data Source Types:

    The Entity Data Picker property editor allows editors to pick one or more entities from a configurable data source. The selected entities are stored as an array of strings, where each string represents the ID of the selected entity.

    Notifications

    Learn how to set up email notifications for actions performed on content items in the Umbraco backoffice.

    You can set up notifications to receive an email when an action is performed on a given content item. To receive notifications, you need to add your email address to your user profile.

    To set up notifications for a content item:

    1. Click ... next to the page or select the page and click Actions in the top-right corner of the screen.

    2. Choose Notifications.

    Registering Document Type localization Files

    The umbraco-package.json file is only registered when placed directly in the /App_Plugins/ or /App_Plugins/{SubFolderName} folder. It will not be recognized in nested subfolders.

    Creating localizations

    Umbraco must be restarted to register the localization manifest. Any subsequent localization text changes will need to be reloaded within the browser.

    Applying localizations

    Property descriptions support Umbraco Flavored Markdown, which uses a different syntax (wrapped in brackets) to avoid conflicts with Markdown headers.

    Sections

    In this article you can learn more about the various sections you can find within the Umbraco Backoffice.

    A section in Umbraco is where you perform specific tasks related to a particular area of Umbraco. For example, Content, Settings, and Users are all sections. You can navigate between the different sections by clicking the corresponding icon in the section menu positioned at the top of the Backoffice.

    The Section menu is the horizontal menu located at the top of the Umbraco Backoffice.

    Below is a short overview of the default sections in Umbraco CMS:

    Content

    The Content section contains the content nodes that make up the website. Content is displayed as nodes in the Content tree.

    Nodes in Umbraco can display the following content states:

    • Grayed-out nodes are not published yet.

    • Pages that are currently locked using the Public Access feature.

    • Pages that contain a collection of pages.

    To create content, you must define it using Document Types.

    For more information, see the article.

    The Media section contains the media for the website. You can create folders and upload media files, such as images and PDFs. Additionally, you can customize the existing Media Types or define your own from the Settings section.

    For more information, see the article.

    The Library section is a central editorial hub for reusable content. Elements are created and managed here, allowing you to define content once and reuse it across as many pages and documents as needed.

    By default, all user groups except Sensitive Data and Translators have access to the Library section.

    For more information, see the article.

    The Settings section allows you to manage website layout files, languages, media, and content types. It also gives you access to more advanced features such as the Log Viewer and extension insights.

    The Settings section consists of:

    Structure

    • Document Types

    • Media Types

    • Member Types

    • Data Types

    Templating

    • Templates (.cshtml files)

    • Partial views (.cshtml files)

    • Stylesheets (.css files)

    Advanced

    • Relations

    • Log Viewer

    • Extension Insights

    • Webhooks

    The Settings section in the Umbraco backoffice has its own set of default dashboards.

    For more information, see the article.

    In this section, you can browse the different packages available for your Umbraco solution. You can also get an overview of all the packages you have installed or created.

    For more information, see the article.

    The Users section allows administrators to manage user accounts, assign permissions, set user roles, and monitor user activity within the backoffice. It provides control over who can access and modify content, media, and settings in the CMS.

    For more information, see the article.

    The Members section allows you to create and manage member profiles and member groups.

    For more information, see the article.

    The Translation section is where you create and manage Dictionary Items. By managing these dictionary items, you can ensure consistent and efficient content translation and maintenance across different languages.

    For more information, see the article.

    To enhance Umbraco's functionality, you can integrate plugins and extensions tailored to specific needs. These add-ons expand Umbraco's capabilities, allowing for a more customized and powerful content management experience.

    For example, you can start with core Umbraco features and later decide to integrate additional products. Currently, Umbraco supports add-on products like:

    • Forms: Simplifies the creation and management of Forms.

    • Deploy: Facilitates smooth deployment processes.

    • Workflow: Enhances content workflows and approval processes.

    • Commerce: Adds e-commerce capabilities to your site.

    When you add an add-on product to Umbraco, it appears in the Backoffice as a new section, seamlessly extending your content management capabilities.

    If you wish to explore the unique features and use cases of Umbraco products, see the article.

    For more information about extending the Umbraco platform through packages and integrations, see the documentation.

    The Help section in Umbraco provides documentation and resources to assist in understanding and effectively using the Umbraco CMS. It typically includes the following in the Welcome to Umbraco Dashboard:

    • Documentation: Comprehensive guides, tutorials, and references covering different aspects of Umbraco.

    • Community Forums: Access to forums where you can ask questions, share knowledge, and seek assistance from other Umbraco community members.

    • Resources: Stay updated with the latest news, access documentation, watch free video tutorials, and register for live demos.

    • Training

    The Help section serves as a valuable resource hub in navigating and leveraging the capabilities of the Umbraco CMS effectively.

    Along with the default sections that come with Umbraco, you can create your own .

    A User can access a particular section based on the User Group permissions.

    Learn more about how to configure the permissions in the article about .

    Unattended Installs

    In some cases, you might need to install Umbraco instances automatically without having to run through the installation wizard to configure the instance.

    You can use the Unattended installs feature to allow for quick installation and set up of Umbraco instances on something like Azure Web Apps.

    This article will give you the details you need to install Umbraco unattended.

    Get clean install of Umbraco

    In order to get a clean instance of Umbraco, follow our installation guide for how to .

    Configure your database

    As you will not be running through the installation wizard when using this feature, you need to manually tell Umbraco which database to use.

    • Set up and configure a new database - see for details.

    • Add the connection string using configuration.

    A value is configured for the keyumbracoDbDSN_ProviderName to ensure usage of the Microsoft.Data.SQLite ADO.NET provider.

    It is recommended that you make use of the values shown below for the Cache, Foreign Keys and Pooling keywords on your connection string.

    The unattended installs feature is disabled by default. In order to enable it, you need to add the following JSON object to a JSON configuration source.

    Remember to set the value of InstallUnattended to true.

    The UnattendedTelemetryLevel can be set to Minimal, Basic, or Detailed. If omitted, Detailed is the default.

    Alternatively you may set your configuration with Environment Variables or other means. Learn more about this in the .

    The keys for this would then be as follows:

    After completing the steps above you can now initialize the installation by booting up the Umbraco instance.

    Once it has completed, you should see the following when visiting the frontend of the site.

    Depending on your preferences, you can use any type of configuration to specify the connection string and login information, as well as enable unattended install. With the extending configuration functionality, it is possible to read from all kinds of sources. One example can be using a JSON file or environment variables.

    Program.cs has a condition, which if met, an appsettings.Local.json file will be added and configured as a configuration source.

    Having intellisense will help you to add your connection string and information needed for the unattended install.

    We have added support for unattended installs with Name, Email and Password, and Connection String as CLI params, which are also available in Visual Studio. There you can fill in your information as follows:

    For running Umbraco in Docker containers, see article.

    Date Only

    Schema Alias: Umbraco.DateOnly

    UI Alias: Umb.PropertyEditorUi.DateOnlyPicker

    Returns: DateOnly?

    The Date Only property editor provides an interface for selecting dates without including time or time zone information. It focuses purely on date selection and returns a DateOnly value.

    Configuration

    You can configure this property editor in the same way as any standard property editor, using the Data Types admin interface.

    To set up a property using this editor, create a new Data Type and select Date Only from the list of available property editors.

    This editor has no configuration options.

    You will be presented with a date input.

    The value returned will have the type DateOnly?.

    With Models Builder:

    Without Models Builder:

    This property editor stores values as a JSON object. The object contains the date as an ISO 8601 string with midnight time and UTC offset.

    The property editor stores values in this JSON format:

    The property editor handles date-only values. Time is set to 00:00:00 and offset to +00:00 for storage consistency. These time components are ignored in the Date Only context.

    1. Create a C# model that matches the JSON schema.

    2. Convert your existing date value to DateTimeOffset for storage.

      If you have a DateOnly:

      If you have a DateTime:

    For an example on how to work with DateOnly property using IContentService see the article.

    Elements

    Learn how to use Elements to add reusable content to your website.

    Instead of replicating the same content on a per-page basis, Elements allow you to create reusable content. By creating your content once, you can reuse it across as many pages and documents as you need.

    Elements are ideal for call-to-action blocks, banners, and other shared content that appears across multiple pages.

    Elements hold one piece of content that's shared and centrally updated everywhere it's referenced. If you instead need editors to compose different content per page from a set of block types, use the instead.

    Library

    Elements are managed from the Library section in the Umbraco Backoffice.

    The Library section is a central editorial hub for reusable content. By default all user groups except Sensitive data and Translators have access to the section.

    If the project was started on versions before Umbraco 18, only the Administrators user group has access to the Library section.

    Manage permissions to the Library section from the Users section in the Umbraco backoffice.

    Manage Elements

    Elements are configured in the Settings section and managed from the Library section. They are referenced in your content using the Element Picker property.

    Build and Configure Elements

    Elements are created as Element Types in the Settings section of the Umbraco backoffice. As with all Element Types, Elements are not routable and are not attached to a Template.

    Toggle the Allow in Library option on the Structure Workspace View to turn your Element Type into an Element.

    Element Type Structure tab with Allow in Library toggled

    You can add groups, tabs, and properties like you would to any other Element and Document Type.

    Since your project will contain different Document Types, group your Elements into a dedicated folder to keep your workspace organized.

    With your Element configured, you can start using it to create reusable content in the Library section.

    1. Click the + icon.

    2. Select which Element Type you want to base the Element on.

    3. Fill in the relevant properties.

    4. Save or Save and Publish once the content is ready.

    To maintain an overview of your reusable content, it can be a good idea to use folders for organizing the content in your Library.

    Use the Info workspace view to find relevant details about the element, such as history and where the element is used.

    Once you have created the elements in the Library section, they can be referenced anywhere an Element Picker has been configured.

    You can add elements to your content in the Content section using an Element Picker. This needs to be added as a property on the Document Type. Read the article to learn more about how to use and configure it.

    Making changes to an Element in the Library section, will update all instances of the content throughout the project.

    Date Time Editors

    The Date Time property editors provide interfaces for selecting dates, times, and time zones. Each editor is designed for specific use cases, from basic date selection to comprehensive date/time handling with time zone support.

    These property editors replace the legacy property editor. They offer more focused functionality and specific return types (such as DateOnly, TimeOnly, DateTime, or DateTimeOffset). You can switch from the legacy Date Time editor by changing your properties to use the new editors.

    Umbraco CMS currently ships with four Date Time editors:

    Editor
    Purpose
    Use Cases
    Return Type
    Preview

    Block Editors

    The Block Editors are property editors that enabled you to build advanced editor tools using a set of predefined Document Types.

    Umbraco CMS currently ships with two Block Editors: the Block List and the Block Grid.

    Customizing Block Editors

    Learn how to create custom views for the blocks used in your Block Grid or Block List property editors.

    Migrate Content to Umbraco 8

    This guide will show you how to migrate the content from your Umbraco 7 site to a site running Umbraco 8.

    Umbraco 8 contains a lot of breaking changes and a lot of code has been cleaned up compared to Umbraco 7. Due to this, it will not be possible to do a direct upgrade from Umbraco 7 to Umbraco 8. You need to migrate your content from your Umbraco 7 site into your Umbraco 8 site and then recreate the rest in the new version.

    A content migration tool has been implemented in Umbraco 8.1.0, to help you with the transition.

    In this guide you can read more about the tool, its limitations, and how to use it in practice.

    In the following section, you can learn more about the limitations of migrating content from Umbraco 7 to Umbraco 8.

    The content migration tool is a database migration, which is made for the database schema of Umbraco 7.14+. This means that in order to do the migration you need to ensure your Umbraco 7 site is running at least Umbraco 7.14.

    Umbraco 8 does not support MySQL databases. This means that the migration will not work when moving from an Umbraco 7 site using MySQL to Umbraco 8 on SQL Server

    The database types that are supported are SQL Server and SQL CE.

    Markdown Editor

    Schema Alias: Umbraco.MarkdownEditor

    UI Alias: Umb.PropertyEditorUi.MarkdownEditor

    Returns: System.Web.HtmlString

    This built-in editor allow the user to use the markdown formatting options, from within a rich text editor-like interface.

    There are three settings available for manipulating the Markdown editor property.

    Collection

    Schema Alias: Umbraco.ListView

    UI Alias: Umb.PropertyEditorUi.Collection

    Returns: IEnumerable<IPublishedContent>

    Collection/List View can be used on Document Types with children, to display those children as a collection in either a grid or a list.

    Once Collections are configured, the parent content item displays its child items in a list view format within the content item itself. If Collections are not configured, the child items are displayed directly in the Content Tree, rather than being grouped within the parent content item.

    Minor Upgrades for Umbraco 7

    This article provides details on how to upgrade to the next minor version when using Umbraco 7.

    Use Elements

    Elements and Blocks (used by the Block List and Block Grid editors) don't mix within the same property. A Block List or Block Grid always stores its block content inline. It cannot be configured so that a block type is either inline content or a reference to a Library Element. To combine both approaches on one page, add an Element Picker property and a Block List/Block Grid property separately.

    {
        Date = dateTimeOffset
    };
    Feedback from user testing has shown that some databases are harder to migrate than others.

    We are collecting a list of these known issues on our GitHub Issue Tracker. There is a community package: Pre-migration health checks that you can install on your Umbraco 7 site before migration. This will help identify and resolve some of these common issues before triggering the migration steps detailed below.

    The migration will transform the data stored in third party editors as well. However, it will be stored as it was in Umbraco 7. If the structure has changed or the property editor doesn't exist, you will still be able to find the data in the database. It will, however, not be available in the backoffice.

    When the migrations are running, Umbraco will go through your entire Umbraco 7 database and update it to the format required for Umbraco 8. The schema will be remodeled and transformed into the correct format and your existing compatible data will be transformed to fit with Umbraco 8.

    These migrations will be running directly on your database. They are transforming schema and data - not transferring. Therefore always ensure that you have a backup before attempting to do this. In case something goes wrong, you will be able to rollback and try again.

    It is highly recommended to clean up your site before running this as it will be quicker.

    • Empty Content recycle bin

    • Empty Media recycle bin

    • Clean up the database version history (can be done with a script or a package like Unversion)

    In the following guide we will migrate the content of an Umbraco 7.13.1 site to Umbraco 8.1.0.

    Before the content migration can start the site has to run Umbraco 7.14+. Make sure to always take a backup of the database before doing an upgrade, and then check the version specific upgrade instructions.

    The site in this example is an Umbraco 7.13.1 site, and we will use Nuget to update it.

    v7 site with content

    Following the general upgrade instructions we will now upgrade via Nuget until we get to this point:

    Upgrading to v7.14

    Install the Pre-migration health checks plugin, and run it health check from the Developer section of the backoffice. This is done to identify and resolve some common database schema issues before migration.

    Once it is upgraded and you have verified everything is working, move on to the next step.

    The first thing to do is to spin up a fresh new Umbraco 8.1+ site. Make sure everything works and that no content is there.

    Fresh 8.1 site

    Take a backup of your database from the Umbraco 7.14 site. Take the information for the backup database and add that to the connectionstring for the Umbraco 8.1 site. If you are running SQL CE, you will have to copy the database over to the new site as well.

    Once the connectionstring is set, the final step is to change the Umbraco version number in the web.config on the Umbraco 8.1 site. Chang it to 7.14.0. This will indicate that there is an upgrade pending and it needs to run the migration.

    Set Umbraco version in the web.config

    The version will be set to 8.1.0, and you need to change it to the version you are currently migrating from.

    When you start the site it will ask you to login and then show you this screen:

    Upgrade database to 8.1

    From here, the automatic migration will take over, and after a little bit you can log in and see your content:

    Content is on 8.1

    Before moving on to this step, make sure that the Umbraco 8 project is no longer running.

    The following files/folders need to be copied into the Umbraco 8 project:

    • ~/Views - do not overwrite the default Macro and Partial View Macro files, unless changes have been made to these.

    • ~/Media

    • Any files/folders related to Stylesheets and JavaScripts.

    • Any custom files/folders the Umbraco 7 project uses, that aren't in the ~/Config or ~/bin.

    • ~/App_Data/UmbracoForms - in the case Umbraco Forms was used on the Umbraco 7 site.

    Merge the configuration files carefully to ensure any custom settings are migrated while none of the default configurations for Umbraco 8 is overwritten.

    You'll have to revisit all templates and custom implementations to get the site up and running, as all markup is still Umbraco 7-specific.

    As you are updating your template files and custom implementation, you should also verify your configuration files and settings.

    Umbraco 8 contains a few changes regarding the Sections in the Umbraco Backoffice. Because of this, you should also check your User Groups and make sure they have access to the appropriate sections.

    Migrating Umbraco Cloud sites

    Follow the steps outlined in the Umbraco Cloud documentation to upgrade your Umbraco 7 site on Cloud.

    What are the limitations?

    Versions supported

    Database types supported

    Known issues

    A migration was introduced in Umbraco 8.6 which can break the migration process. See for more details.

    There are two ways to work around this issue:

    • Migrate to version 8.5 as a first step and then post-migration, carry out a normal Umbraco upgrade to the latest version of Umbraco 8, or

    • Install the following community Nuget Package: into your Umbraco 8 project before running the migration (no configuration required). This package was created by Umbraco Gold Partner

    Third party property editors

    Learn more about that in the Data Types Migrations

    Migrating data types

    When migrating content from Umbraco 7 to Umbraco 8, the Data Type 'pre-value' structure has changed. In Umbraco 8, the term 'pre-values' no longer exists and is instead referred to as property editor configuration.

    In Umbraco 8, property editor configuration is a strongly typed object. There are plenty of examples in the .

    This configuration is stored differently in Umbraco 8 than it was in Umbraco 7. In Umbraco 7, each pre-value property was stored as a different row in a different database table. In Umbraco 8 this is simplified and property editor configuration is stored as the JSON serialized version of the strongly typed configuration object.

    When upgrading from Umbraco 7 to Umbraco 8, Umbraco has no way of knowing how custom property editors have intended to structure their configuration data. During the upgrade, Umbraco will convert the key/value pairs from the old pre-value database table into a serialized JSON version of those values. There is a reasonable chance that the end result of this data conversion is not compatible with the custom property editor.

    What will happen

    How it works

    Step 1: Upgrading to 7.14+

    When upgrading an old website, check if you are using obsolete properties in your Data Types. These should be changed to their updated counterparts. The migration will fail if you are still using obsolete properties.

    The updated properties are:

    • Content Picker

    Step 2: Migrating content to Umbraco 8

    If you have customized the UsersMembershipProvider on your Umbraco 7 site you need to copy that over to the 8.1 web.config as well. Additionally you need to update the type attribute to be type="Umbraco.Web.Security.Providers.UsersMembershipProvider, Umbraco.Web".

    This also includes the attribute useLegacyEncoding value. Make sure that this setting is copied into your new Umbraco 8 site, as it is needed in order to log in.

    Please be aware that this is a content migration. If you go to the frontend after following these steps, it will throw errors.

    At this point you will have the content but nothing else.

    Step 3: Files migration

    Are you planning on continuing the migration to the latest version on Umbraco CMS?

    Then you can skip the step to revisit the template files and custom implementation. We highly recommend waiting with this step until you've reached the latest version.

    If you're stopping at Umbraco 8, you can learn more about .

    Step 4: Post-migration checks

    Preview toggles if a preview of the markdown should be displayed beneath the editor in the content view.
  • Default value is inserted if no content has been saved to the Document Type using this property editor.

  • Overlay Size is used to select the width of the link picker overlay in the content view.

  • Content Example

    The conversion from markdown to HTML is handled by the registered implementation of IMarkdownToHtmlConverter.

    To understand this more and how you may customize it to your needs, see the article on Markdown to HTML Conversion.

    See the example below to see how a value can be added or changed programmatically. To update a value of a property editor you need the Content Service.

    Although the use of a GUID is preferable, you can also use the numeric ID to get the page:

    If Models Builder is enabled you can get the alias of the desired property without using a magic string:

    Data Type Definition Example

    Markdown Editor definition example
    @Model.MyMarkdownEditor
    @Model.Value("MyMarkdownEditor")
    @using Umbraco.Cms.Core.Services
    @inject IContentService ContentService
    @{
        // Create a variable for the GUID of the page you want to update
        var guid = Guid.Parse("32e60db4-1283-4caa-9645-f2153f9888ef");
    
        // Get the page using the GUID you've defined
        var content = ContentService.GetById(guid); // ID of your page
    
        // Create markdown value
        var markdownValue = new HtmlString("#heading  \n**strong text**");
    
        // Set the value of the property with alias 'myMarkdownEditor'.
        content.SetValue("myMarkdownEditor", markdownValue);
    
        // Save the change
        ContentService.Save(content);
    }
    @{
        // Get the page using it's id
        var content = ContentService.GetById(1234);
    }
    @using Umbraco.Cms.Core.PublishedCache
    @inject IPublishedContentTypeCache PublishedContentTypeCache
    @{
        // Set the value of the property with alias 'myMarkdownEditor'
        content.SetValue(Home.GetModelPropertyType(PublishedContentTypeCache, x => x.MyMarkdownEditor).Alias, markdownValue);
    }

    The example below demonstrates how to add values programmatically using a Razor view. However, this is used for illustrative purposes only and is not the recommended method for production environments.

    It is possible to add more columns to the collection, via adding the properties through the picker modal. These properties are based on the Data Types which are used by the Document Type. The properties will listed for selection.

    Once you have selected a column you want to display, define what its heading label should be and what kind of value it should display. You can also move the headers around, re-ordering how they should look. This is done by the move icon on the left side of the alias.

    The template section is where you define what kind of value you want to display. The value of the column is in the value variable.

    Collection comes with two layouts by default. A list and a grid view. These views can be disabled if you are not interested in any of them.

    You can also make your own layout and add it to the settings. For example, if you wanted to change the width or length of the grid, you will be able to do so.

    Will sort your collection by the selection you choose in the dropdown. By default it selects "Last edited" and you get the following three columns:

    • Last edited - When the content node was last edited and saved.

    • Name - Name of the content node(s).

    • Created by - This is the user who the content node was created by.

    You can add more sorting to this collection by adding more datatypes to the columns in the "Columns Displayed" section.

    You can select order of the content nodes displayed, "Ascending [a-z]" or "Descending [z-a]". The order is affected by the "Order By" selection.

    Defines how many child content nodes you want to see per page. This will limit how many content items you will see in your collection. If you set it to 5, then only 5 content items will be shown in the collection.

    Changes the icon in the backoffice of the collection. By default it will look like the image below.

    Collection icon example

    You can change the name of the collection itself. Default if empty: 'Child Items'.

    Enable this to show the Content Workspace View by default instead of the collection's.

    This example shows how to use a generic field from a child item and display its value in a collection.

    Collection content email label template

    You can use the Umbraco Flavored Markdown syntax to display the label value. Here, the {=value} placeholder retrieves the value of the Email property and displays it in the collection, as shown in the image below:

    Collection content email value displayed

    First, a Content Picker property needs to be present on the content item. In this example, the child item has gotten a Content Picker Data Type with the alias of contentPicker.

    Collection content picker

    The child item has a document and the value that should be displayed is the name of the picked value. The next step is to reconfigure the template value in the collection setting.

    Collection content picker

    This will take the value picked up by the content picker.

    Collection content picker with picked value

    And display it in the collection. Shown in the example below:

    Open up the Package Console and type: Update-Package UmbracoCms

  • Choose "No to All" by pressing the "L" when prompted.

    • If there are any specific configuration changes required for the version you are upgrading to then they will be noted in the version-specific guide.

  • Alternatively, you can use the Visual Studio NuGet Package Manager to upgrade:

    1. Open the NuGet Package Manager and select the Updates pane to get a list of available updates.

    2. Choose the package called UmbracoCms and select update.

    The upgrade will run through all the files and make sure you have the latest changes while leaving the files you have updated.

    If you're not upgrading to 7.2.0 or higher then you should follow these extra instructions. If you are upgrading to 7.2.0+ then you can skip this and go to Merge UI.xml and language.

    You will be asked to overwrite your web.config file and the files in /config, make sure to answer No to those questions.

    For some inexplicable reason, the installation will fail if you click "No to All" (in the GUI) or answer "L" (in the package manager console) to the question: "File 'Web.config' already exists in project 'MySite'. Do you want to overwrite it?" So make sure to only answer "No" (in the GUI) or "N" (in the package manager console).

    File conflict dialog with a web.config file in conflict
    File conflict console message with multiple files in conflict

    We will overwrite the web.config file. We'll back it up so don't worry. You can find the backup in App_Data\NuGetBackup\20140320-165450\. The 20140320-165450 bit is the date and time when the backup occurred, which varies. You can then merge your config files and make sure they're up to date.

    Download the .zip file for the new version you are upgrading to from https://our.umbraco.com/download

    Copy the following folders from inside the .zip file over the existing folders in your site:

    • /bin

    • /Umbraco

    • /Umbraco_Client

    You can expect some changes to the following configuration files:

    • Any file in the /Config folder

    • The /Global.asax file

    • The web.config file in the root of your site (Important: make sure to copy back the version number, and the connection string as they were.)

    • In rare cases, the web.config file in the Views folder

    Use a tool like WinMerge to check changes between all of the config files. Depending on when you last did this there may have been updates to a few of them.

    There's also the possibility that files in the /Config folder are new or have been removed(we note this in the release notes). WinMerge (and other diff tools) is able to compare folders as well so you can spot these differences.

    Up until version 6.0.0 it was necessary to change the version number in ClientDependency.config. This was to clear the cached HTML/CSS/JS files in the backoffice. Change the current version number to one that's higher than that. Make sure not to skip this step as you might get strange behavior in the backoffice otherwise.

    Some packages (like Contour and Umbraco Forms) add dialogs to the UI.xml. Make sure to merge those changes back in from your backup during the upgrade so that the packages continue to work. This file can be found in: /Umbraco/Config/Create/UI.xml.

    Packages like Contour, Umbraco Forms, and Courier also make changes to the language files located in: /Umbraco/Config/Lang/*.xml (typically en.xml).

    After copying the files and making the config changes, you can open your site. You should see the installer which will guide you through the upgrade.

    The installer will do two things:

    • Update the version number in the web.config

    • Upgrade your database in case there are any changes

    We are aware that, currently, the installer is asking you for the database details of a blank database while upgrading. In the near future this will be pre-filled with your existing details and the wording will be updated. So no need to be scared. Enter the details of your existing database and Umbraco will upgrade it to the latest version when necessary.

    One important recommendation is to always remove the install folder immediately after upgrading Umbraco and never to upload it to a live server.

    Google Chrome has notoriously aggressive caching. If something doesn't seem to work well in the backoffice, make sure to clear cache and cookies thoroughly (for other browsers as well). Normally the browser cache problem is automatically handled in an Umbraco upgrade by modifying the config/ClientDependency.config version number. If you wish to re-force this update you can increment this version number. This will ensure that any server-side cache of JavaScript and stylesheets gets cleared as well.

    One way to nudge the cache in Chrome is to open the developer tools (F12) and go to the settings (the cog icon). There will be a checkbox that says "Disable cache (while DevTools is open)". Once this checkbox is on you can refresh the page and the cache should be invalidated. To force it even more, the "reload" button next to your address bar now has extra options when you right-click it. It should have "Normal reload", "Hard reload" and "Empty cache and hard reload" now. The last option is the most thorough and you might want to try that.

    There are hosting providers (we know of one: RackSpace Cloud) that require proper casing of file and folder names. Generally, on Windows, this is not a problem. Is your hosting provider forcing proper casing? You'll then need to verify that folders and files are named in the same casing as the version you're upgrading to.

    Umbraco can create an SQL Server database for you during the unattended install process. The user specified by the credentials in your connection string needs to have the CREATE DATABASE permission granted and the global setting InstallMissingDatabase is set to true.

    If your connection string is for SQLite or SQL Server Express LocalDB it is assumed that a database should be created when missing. This is regardless of the value of the InstallMissingDatabase setting.

    SQL Server Example in appsettings.json

    The 'umbracoDbDSN_ProviderName' attribute sets the .NET Framework data provider name for the DataSource control's connection. For more information on the data providers included in the .Net Framework, see the Microsoft Documentation.

    Media Picker

    Schema Alias: Umbraco.MediaPicker3

    UI Alias: Umb.PropertyEditorUi.MediaPicker

    Returns: IEnumerable<MediaWithCrops> or MediaWithCrops

    This property editors returns one of the following:

    • A collection (IEnumerable<MediaWithCrops>) if the Pick multiple items setting is enabled.

    • A single MediaWithCrops item if the Pick multiple items setting is disabled.

    Use setting to limit the picker to only select Media Items of these types.

    Use this setting to enable the property to contain multiple items. When this is enabled the property editor returns an IEnumerable<MediaWithCrops>.

    You can still set the maximum amount to 1. Do so when you want to retrieve a collection but only allow the Content Editors to select one Media Item.

    Use this setting to enforce a minimum and/or maximum amount of selected Media Items.

    This setting is used to limit the Media Picker to certain parts of the Media Tree.

    Use this setting to overrule user permissions, to enable any user of this property to pick any Media Item of the chosen Start node.

    When this setting is enabled, a user can access the media available under the selected "Start Node" (/Design in this case). This applies even if they normally lack access. The access is granted specifically when using this particular Media Picker.

    Enable the focal point setter, do only enable this if the focal point is used or if you have Image crops defined.

    Define local image crops. Local image crop data is stored on the document in this property. This means it can differentiate between documents.

    This is different from Global crops as they are defined on the Media Item, making the crops shared between all usage of that Media Item.

    Global crops are configured on the Image Cropper property of the Image Media Type

    Both local and global crops are retrieved using the method GetCropUrl. If crops with identical aliases are defined both locally and globally, the locally defined crops are always prioritized by GetCropUrl.

    The following is an example of how to retrieve a crop from a MediaWithCrops entry:

    You can retrieve globally defined crops explicitly by using GetCropUrl on the UrlHelper:

    See the example below to see how a value can be added or changed programmatically. To update a value of a property editor you need the .

    The following sample will update a single image in a Media Picker.

    Although the use of a GUID is preferable, you can also use the numeric ID to get the page:

    If Models Builder is enabled you can get the alias of the desired property without using a magic string:

    Backoffice

    Learn more about the Umbraco backoffice which is the admin side of your Umbraco website

    In this article you can learn more about the common terms and concepts that are used throughout the Umbraco backoffice.

    When you go to the backoffice for the first time, you're presented with the login screen.

    Login screen

    Read more about the login screen.

    A section in Umbraco is where you do specific tasks related to that section. For example Content, Settings and Users. You can navigate between the different sections of the backoffice by clicking the corresponding icon in the section menu.

    The Section menu is the horizontal menu located on the top of the backoffice.

    Section

    Read more about the section menu.

    A tree is a hierarchical list of items related (and usually restricted) to a specific concept, like for example content or media.

    You can expand trees by clicking the side arrow to the left of the node.

    A node is an item in a tree. Media section items appear as nodes in the Media tree, while pages and content are displayed in the Content tree, and so on.

    A dashboard is the main view you are presented with when entering a section within the backoffice. It can be used to show valuable information to the users of the system.

    An editor is what you use to edit different items within the backoffice. There are editors specific to editing stylesheets, there are editors for editing Partial Views, and so forth.

    Content is what you find in the Content section. Each item in the tree is called a content node. Each content node in the content tree consists of different fields, and each of them is defined by a Document Type.

    Document Types define the types of content nodes that backoffice users can create in the content tree. Each Document Type contains different properties. Each property has a specific Data Type for example text or number.

    Every Document Type has properties. These are the fields that the content editor is allowed to edit for the content node.

    Each Document Type property has a Data Type that defines the type of input of that property. Data Types reference a Property Editor and are configured in the Umbraco backoffice in the Settings section. A Data Type can be something basic (text string, number, true/false) or more complex (multi-node tree picker, image cropper, etc).

    A property editor is a view used by Data Types to insert content into Umbraco. An example of a property editor is the Textarea. It's possible to have many Textarea Data Types with different settings that all use the Textarea property editor.

    Media items are used to store assets like images and video within the Media section and can be referenced from your content.

    Media Types are similar to Document Types in Umbraco, except they are specifically for media items in the Media section.

    Umbraco includes the following default Media Types - Article, Audio, File, Folder, Image, Vector Graphics (SVG), and Video.

    A member is someone who has access to signup, register, and login into your public website and is not to be confused with Users.

    Similar to a Document Type and a Media Type. You are able to define custom properties to store on a member such as Twitter username or website URL.

    A Template is where you define the HTML markup of your website and also where you output the data from your content nodes.

    A package is the Umbraco term for an add-on or plugin used to extend the core functionalities in Umbraco. The packages can be found on the , and the can also be browsed directly in the backoffice of the Umbraco CMS.

    A user is someone who has access to the Umbraco backoffice and is not to be confused with Members. When Umbraco has been installed a user will automatically be generated with the login (email) and password entered during installation. Users can be created, edited, and managed in the User section.

    Document Blueprint provide a blueprint for content nodes based on an existing node.

    Date Time (with Time Zone)

    Schema Alias: Umbraco.DateTimeWithTimeZone

    UI Alias: Umb.PropertyEditorUi.DateTimeWithTimeZonePicker

    Returns: DateTimeOffset?

    The Date Time with Time Zone property editor provides a comprehensive interface for selecting dates, times, and time zones. It stores values as ISO 8601 date/time strings with time zone information. This makes it ideal for applications that need accurate date handling across different time zones.

    Configuration

    You can configure this property editor in the same way as any standard property editor, using the Data Types admin interface.

    To set up a property using this editor, create a new Data Type. Select Date Time (with time zone) from the list of available property editors.

    You will see the configuration options as shown below.

    • Time format - Specifies the level of precision for time values shown and stored by the editor.

    • Time zones - Controls how time zones are available in the property editor.

    • HH:mm - Displays hours and minutes (e.g., 14:30). Suitable for most general use cases.

    • HH🇲🇲ss - Displays hours, minutes, and seconds (e.g., 14:30:45). Use this when you need more precise timing.

    • All - Displays the full list of time zones (for example, America/New_York, Europe/Stockholm).

    • Local - Displays only the local time zone of the user's browser/computer. Useful for simplifying the UI when time entries should always be based on the user’s local context.

    • Custom - Allows you to define a list of time zones. When you select this option, a dropdown appears. You can search and select from the full IANA time zone list. Add multiple zones to restrict user selection to only the zones you specify.

    The selected time zone affects how the date/time is displayed and stored. When you select a time zone, the value will be saved with the corresponding offset (e.g., 2025-01-01T14:30:00+01:00). Daylight saving time is also taken into account.

    You will be presented with date, time, and time zone inputs. The time zone input allows typing, which filters the list of presented time zones.

    If your browser time zone appears in the list and no date is stored yet, it will be pre-selected by default.

    When you select a time zone different from your browser's local time zone, the editor displays a helpful conversion message. This shows what the selected date and time would be equivalent to in your local time zone, making it easier to understand the time difference.

    If only one time zone is available, you will see a label with the time zone name instead.

    The value returned will have the type DateTimeOffset?. This allows you to work with the date/time value while preserving time zone information.

    Convert to UTC time:

    Convert to DateTime:

    This property editor stores values as a JSON object. The object contains both the date (as an ISO 8601 string) and the selected time zone identifier.

    The property editor stores values in this JSON format:

    1. Create a C# model that matches the JSON schema.

    2. Create an instance of the created class with the desired values.

    3. Inject the IJsonSerializer and use it to serialize the object.

    4. Inject the IContentService

    For an example on how to work with a date property using IContentService see the article.

    Minor Upgrades for Umbraco 8

    This article provides details on how to upgrade to the next minor version when using Umbraco 8.

    Sometimes there are exceptions to these guidelines, which are listed in the .

    It is necessary to run the upgrade installer on each environment of your Umbraco site. If you want to update your staging and live site you need to repeat the steps below. Make sure you click through the install screens so that your upgrade is complete.

    In this article you will find instructions for 3 different ways of upgrading:

    and patches the migration process so you can migrate directly from the latest Umbraco 7 to Umbraco 8.6+ without encountering the above issue.
    .

    There are 3 options that a developer can choose to do to work around this automatic data conversion:

    1: Implement a custom IPreValueMigrator

    This option requires you to create a custom C# migrator for each of your custom property editors that store custom configuration data. It will also require that you implement these migrators before you run the Umbraco 8 content migration.

    To do this, you will create an implementation of IPreValueMigrator or inherit from the base class DefaultPreValueMigrator.

    There are plenty of examples of this in the Umbraco-CMS codebase.

    You will then need to register them in a composer:

    When running the migrations and encountering a custom configuration, Umbraco will utilize the PreValueMigrator when converting the old pre-values into the new JSON format.

    2: Update your Angular configuration (pre-value) and property editor

    This option means that you will choose to use the automatically converted JSON data format. In this case, it will mean updating your pre-value and property editors to use the new JSON configuration data. The converted data won't be much different than the original/intended data format so this might not be too much work.

    3: Update the Angular configuration (pre-value) editor

    With this option the configuration/pre-value editor needs to be updated to transform the JSON converted data into the data structure you want. When this is done and when the Data Type is saved again, the JSON data structure will be saved back to the database. Your property editor will then continue to work.

    This will require you to update and save all custom pre-value editors to transform the converted structures back to your intended data structure.

    Run an unattended upgrade (v8.12+)

    1. Open up the Package Console and type: Update-Package UmbracoCms

    2. Choose "No to All" by pressing the "L" when prompted.

      • If there are any specific configuration changes required for the version you are upgrading to then they will be noted in the version-specific guide.

    Alternatively, you can use the Visual Studio NuGet Package Manager to upgrade:

    1. Open the NuGet Package Manager and select the Updates pane to get a list of available updates.

    2. Choose the package called UmbracoCms and select update.

    The upgrade will run through all the files and make sure you have the latest changes while leaving files you have updated.

    Download the .zip file for the new version you are upgrading to from https://our.umbraco.com/download

    Copy the following folders from inside the .zip file over the existing folders in your site:

    • /bin

    • /Umbraco

    You can expect some changes to the following configuration files:

    • Any file in the /Config folder

    • The /Global.asax file

    • The web.config file in the root of your site (Important: make sure to copy back the version number, and the connection string as they were.)

    • In rare cases, the web.config file in the /Views folder

    Use a tool like WinMerge to check changes between all of the config files. Depending on when you last did this there may have been updates to few of them.

    There's also the possibility that some files in the /Config folder are new or some have been removed (we do make a note of this in the release notes). WinMerge (and other diff tools) can compare folders as well so you can spot these differences.

    Some packages like Umbraco Forms add dialogs to the UI.xml. Make sure to merge those changes back in from your backup during the upgrade so that the packages continue to work. This file can be found in: /Umbraco/Config/Create/UI.xml.

    Packages like Umbraco Forms and Courier also make changes to the language files located in: /Umbraco/Config/Lang/*.xml (typically en.xml).

    After copying the files and making the config changes, you can open your site. You should see the installer which will guide you through the upgrade.

    The installer will do two things:

    • Update the version number in the web.config

    • Upgrade your database in case there are any changes

    We are aware that, currently, the installer is asking you for the database details of a blank database while upgrading. In the near future this will be pre-filled with your existing details and the wording will be updated. So no need to be scared. Enter the details of your existing database and Umbraco will upgrade it to the latest version when necessary.

    When upgrading your Umbraco project to Umbraco v8.12+ it is possible to enable the upgrade to run unattended. This means that you will not need to run through the installation wizard when upgrading.

    Below you will find the steps you need to take in order to upgrade your project unattended.

    1. Add the Umbraco.Core.RuntimeState.UpgradeUnattended key to appSettings in your web.config file.

    2. Set the value of the key to true.

    In order to trigger the actual upgrade, the correct version number needs to be set.

    It is important to use the version number of the version that you are upgrading to. If this is not set, the upgrade will not run even if the UpgradeUnattended key has been set to true.

    1. Locate the ConfigurationStatus key in the appSettings section in your web.config file.

    2. Update the value to match the Umbraco version that you are upgrading to.

    With the correct configuration applied, the project will be upgraded on the next boot.

    The Runtime level will use Run instead of Upgrade in order to allow the website to continue to boot up directly after the migration is run, instead of initiating the otherwise required restart.

    Follow the steps outlined below to use run unattended upgrades in a load balanced setup.

    1. Upgrade Umbraco via NuGet in Visual Studio. Make sure the Umbraco.Core.ConfigurationStatus key in appSetting in the web.config file is updated to match the target version.

    2. Deploy to all environments, including the updated appSetting for Umbraco.Core.ConfigurationStatus.

    3. Set the Umbraco.Core.RuntimeState.UpgradeUnattended key in appSetting in the web.config to true for the Main server only.

    4. Request a page on the Main server and the upgrade will run automatically.

    5. Wait for the upgrade to complete.

    6. Browse the Read-Only servers and make sure they do not show the “upgrade required” screen.

    One important recommendation is to always remove the install folder immediately after upgrading Umbraco and never to upload it to a live server.

    Google Chrome has notoriously aggressive caching, so if something doesn't seem to work well in the backoffice, make sure to clear cache and cookies thoroughly (for other browsers as well). Normally the browser cache problem is automatically handled in an Umbraco upgrade by modifying the config/ClientDependency.config version number. If you however wish to re-force this update you can increment this version number which will ensure that any server-side cache of JavaScript and stylesheets gets cleared as well.

    One way to nudge the cache in Chrome is to open the developer tools (F12) and go to the settings (the cog icon). There will be a checkbox that says "Disable cache (while DevTools is open)". Once this checkbox is on you can refresh the page and the cache should be invalidated. To force it even more, the "reload" button next to your address bar now has extra options when you right-click it. It should have "Normal reload", "Hard reload" and "Empty cache and hard reload" now. The last option is the most thorough and you might want to try that.

    Upgrade manually from a zip file

    There are hosting providers (we know of one: RackSpace Cloud) that require proper casing of file and folder names. Normally on Windows this is not a problem. If your hosting provider however forces proper casing, you will need to verify that the folder and file names are in the same casing as in the newest version you're upgrading to.

    Check out the section about .

    Enable the feature

    Check the ConfigurationStatus

    Run the upgrade

    While the upgrade processes are running, any requests made to the site will be "put on hold", meaning that no content will be returned before the upgrade is complete.

    Boot order

    The upgrade is run after Composers but before Components. This is because the migration requires services that are registered in Composers and Components requires that Umbraco and the database is ready.

    Content Example

    See the example below to see how a value can be added or changed programmatically. To update a value of a property editor you need the Content Service.

    Although the use of a GUID is preferable, you can also use the numeric ID to get the page:

    If Models Builder is enabled you can get the alias of the desired property without using a magic string:

    New Date Time property editors are available. They offer more focused functionality and time zone support. These editors will eventually replace the current Date Time property editor, so consider using them for new implementations.

    Add values programmatically

    The example below demonstrates how to add values programmatically using a Razor view. However, this is used for illustrative purposes only and is not the recommended method for production environments.

    Dropdown

    Schema Alias: Umbraco.DropDown.Flexible

    UI Alias: Umb.PropertyEditorUi.Dropdown

    Returns: String or IEnumerable<string>

    Displays a list of preset values. Either a single value or multiple values (formatted as a collection of strings) can be returned.

    Settings

    Enable multiple choice

    If enabled, editors will be able to select multiple values from the dropdown otherwise only a single value can be selected.

    Add options

    Options are the values which are shown in the dropdown list. You can add, edit, or remove values here.

    You can use dictionary items to translate the options in a Dropdown property editor in a multilingual setup. For more details, see the article.

    Although the use of a GUID is preferable, you can also use the numeric ID to get the page:

    If Models Builder is enabled you can get the alias of the desired property without using a magic string:

    Date Time (Unspecified)

    Schema Alias: Umbraco.DateTimeUnspecified

    UI Alias: Umb.PropertyEditorUi.DateTimePicker

    Returns: DateTime?

    The Date Time (Unspecified) property editor provides an interface for selecting dates and times without including time zone information.

    Configuration

    You can configure this property editor in the same way as any standard property editor, using the Data Types admin interface.

    To set up a property using this editor, create a new Data Type and select Date Time (Unspecified) from the list of available property editors.

    You will see the configuration options as shown below.

    • Time format - Specifies the level of precision for time values shown and stored by the editor.

    • HH:mm - Displays hours and minutes (e.g., 14:30). Suitable for most general use cases.

    • HH🇲🇲ss - Displays hours, minutes, and seconds (e.g., 14:30:45). Use this when you need more precise timing.

    You will be presented with a date and time input. This editor focuses only on the date and time components, unlike the time zone version.

    The value returned will have the type DateTime?.

    With Models Builder:

    Without Models Builder:

    This property editor stores values as a JSON object. The object contains the date as an ISO 8601 string.

    The property editor stores values in this JSON format:

    The property editor handles unspecified date and time values without time zone information. The value is stored with offset +00:00 for consistency. The offset is ignored unless you replace this editor with the Date Time (with time zone) version.

    1. Create a C# model that matches the JSON schema.

    2. Convert your existing DateTime value to DateTimeOffset for storage.

    3. Create an instance of the class with the DateTimeOffset value.

    For an example on how to work with a date property using IContentService see the article.

    File Upload

    Schema Alias: Umbraco.UploadField

    UI Alias: Umb.PropertyEditorUi.UploadField

    Returns: string

    Adds an upload field, which allows documents or images to be uploaded to Umbraco.

    You can define which file types should be accepted through the upload field.

    In code, the property is a string, which references the location of the file.

    Example: "/media/o01axaqu/guidelines-on-remote-working.pdf"

    Document Picker

    Schema Alias: Umbraco.ContentPicker

    UI Alias: Umb.PropertyEditorUi.DocumentPicker

    Returns: IPublishedContent

    The Document Picker opens a panel to pick a specific page from the content structure. The value saved is the selected nodes .

    See the example below to see how a value can be added or changed programmatically. To update a value of a property editor you need the .

    Although the use of a GUID is preferable, you can also use the numeric ID to get the page:

    Refreshing the Tree View

    Learn how to manually reload the content tree to reflect changes made by other editors.

    When editing content, the content tree will refresh itself when the content is saved.

    You can also manually reload parts of or the entire content tree to refresh it or to load changes made by other editors.

    To reload the content tree:

    1. Click ... next to the Content heading.

    2. Choose Reload children.

    The Document Picker was formerly known as the Content Picker in version 13 and below.

    The renaming is purely a client-side UI change, meaning the property editor still uses the Umbraco.ContentPicker schema alias.

    Image Cropper

    Schema Alias: Umbraco.ImageCropper

    UI Alias: Umb.PropertyEditorUi.ImageCropper

    Returns: MediaWithCrops

    Returns a path to an image, along with information about focal point and available crops.

    When the Image Cropper is used on a Media Type the crops are shared between all usages of a Media Item. This is called global crops.

    If the Image Cropper is used on a Document Type, the file and crops will be local to the Document.

    Notice that it is possible make local crops on shared Media Items via the Media Picker Property Editor.

    Settings

    Define Crops

    You can add, edit & delete crop presets the cropper UI can use.

    The Image Cropper provides a UI to upload an image, set a focal point on the image, and use predefined crops.

    By default, images in the Image Cropper will be shown based on a set focal point and only use specific crops if they are available.

    The Image Cropper comes with 3 modes:

    • Uploading an image

    • Setting a focal point

    • Cropping the image to predefined crops

    The editor exposes a drop area for files. Select it to upload an image.

    By default, the Image Cropper allows the editor to set a focal point on the uploaded image.

    All the preset crops are shown to give the editor a preview of what the image will look like on the frontend.

    The editor can fit the crop to the image to ensure that the image is presented as intended.

    is image processing middleware for ASP.NET.

    We bundle this package with Umbraco and you can therefore take full advantage of all its features for resizing and format changing. Learn more about the built in processing commands in .

    The Image Cropper comes with an API to generate crop URLs. You can also access the raw data directly as a dynamic object.

    For rendering a cropped media item, the .GetCropUrl is used:

    The third parameter is HtmlEncode and is by default set to true. This means you only need to define the parameter if you want to disable HTML encoding.

    Or, alternatively using the MediaWithCrops extension method:

    Set the htmlEncode to false so that the URL is not HTML encoded

    To update a content property value you need the .

    The following sample demonstrates how to add or change the value of an Image Cropper property programmatically. The sample creates an API controller with an action, which must be invoked via a POST request to the URL written above the action.

    If you use Models Builder to generate source code (modes SourceCodeAuto or SourceCodeManual), you can use nameof([generated property name]) to access the desired property without using a magic string:

    Crop URLs are not limited to usage within a view. IPublishedContent has a GetCropUrl extension method, which can be used to access crop URLs anywhere.

    The following sample demonstrates how to use GetCropUrl to retrieve URLs for all crops defined on a specific image:

    Log Viewer

    Information on using the Umbraco log viewer

    Umbraco ships with a built-in Log Viewer feature. This allows you to filter, view log entries, perform complex search queries, and analyze logs for debugging. You can find the Log viewer in the Settings section of the Umbraco backoffice.

    Umbraco's Log Viewer uses structured logging and a query language, so you can search for specific scenarios instead of scanning raw text. For example, finding every log entry tied to one request ID, or every entry where Duration exceeds 1000ms. This makes debugging and pattern-spotting easier.

    Here are some example queries to help you get started. For more details on the syntax, see the project.

    • Find all logs that are from the namespace 'Umbraco.Core' StartsWith(SourceContext, 'Umbraco.Core')

    Creating Media

    Learn how to work with different types of Media content on your Umbraco website.

    Media in Umbraco CMS is handled the same way as content. You define Media Types that act as a base for media items. The following default Media Types are available:

    • Article - used for uploading and storing documents.

    • Audio - used for uploading and storing digital audio files.

    • File - used for uploading and storing different types of files in the Media section.

  • If you frequently use a custom query, you can save it for quick access. Type your query in the search box and click the heart icon to save it with a friendly name. Saved queries are stored in the umbracoLogViewerQuery table in the database.

    Umbraco allows you to implement a custom ILogViewerRepository and ILogViewerService to fetch logs from alternative sources, such as Azure Table Storage.

    To fetch logs from Azure Table Storage, extend the LogViewerRepositoryBase class from Umbraco.Cms.Infrastructure.Services.Implement.

    Azure Table Storage requires entities to implement the ITableEntity interface. Since Umbraco's default log entity does not implement this, a custom entity (AzureTableLogEntity) must be created to ensure logs are correctly fetched.

    Create a new implementation of ILogViewerService. Amongst other things, this is responsible for figuring out whether a provided log query is allowed. Again a base class is available.

    Umbraco needs to be made aware that there is a new implementation of an ILogViewerRepository and an ILogViewerService. These need to replace the default ones that are shipped with Umbraco.

    With the above three classes, the setup is in place to view logs from an Azure Table. However, logs are not yet persisted into the Azure Table Storage account. To enable persistence, configure the Serilog logging pipeline to store logs in Azure Table Storage.

    1. Install Serilog.Sinks.AzureTableStorage from NuGet.

    2. Add a new sink to appsettings.json with credentials to persist logs to Azure.

    The following sink needs to be added to the Serilog:WriteTo array.

    This example uses the same Azurite-compatible connection string as the repository above, so the two stay in sync for local testing.

    Replace it with your real Azure Storage connection string when deploying, for example: DefaultEndpointsProtocol=https;AccountName=ACCOUNT_NAME;AccountKey=KEY;EndpointSuffix=core.windows.net. Update the repository's connection string to match.

    For more in-depth information about logging and how to configure it, see the Logging article.

    Implementing Your Own Log Viewer Source

    Creating a Custom Log Viewer Repository

    This implementation requires the Azure.Data.Tables NuGet package.

    The connection string above must match the one used by the Serilog sink configured in . If the two point at different storage accounts, this repository queries a table that was never written to. The Log Viewer then fails with an error stating the table does not exist. Read the connection string from configuration rather than hardcoding it, so both sides always agree.

    Folder - a container for organizing media items in the Media section tree.

  • Image - used for uploading and storing images.

  • Vector Graphics (SVG) - used for uploading and storing Scalable Vector Graphics (SVG) files which are text files containing source code to draw the desired image.

  • Video - used for uploading and storing video files.

  • The default Media Types aim to cover most needs for media on a website. You do not need to define your Media Types to start using the Media section. The tools for organizing and uploading the media are already in place.

    You can upload media in two different ways:

    • Through the Media section and

    • Through the Content section

    From the Media section in the Umbraco backoffice, you can add new media items by following either of the approaches defined below:

    • Use the Create dialog to create a new Media item in the Media section

      • The Media item will be created based on the type you choose.

      • Upload the image or file, give the Media item a name, and click Save.

    Upload Media - Create Button
    • Use the Drag and drop feature to add your files to the Media section.

      • Umbraco will automatically detect the Media Type and create the Media item.

      • You can drop entire folder structures to recreate that same structure in the Media section.

    Upload Media - Media section

    New media items can be added to your site without interrupting the content creation flow. This can be done following either of the two approaches outlined below.

    • Drag and drop the image(s) from your file explorer directly into the Media Picker property on the Content page.

      • Images added this way is automatically added to the user's start node in the Media section of the Umbraco backoffice.

    Drag and drop images directly into the content
    • Select the "+" icon to open the "Select media" dialog where you can add images from your file explorer directly or using drag and drop.

    Add images from the "Select media" dialog

    It is always a good idea to start by creating a folder for your media items. It can be a good idea to align these folders with the content on your website. This will give the editors a better overview of the files and enable them to upload media items in the correct place.

    Follow these steps to create a folder in the Media section:

    1. Go to the Media section.

    2. Select ... next to Media.

    3. Select Create.

    4. Select Folder.

    5. Enter a name for the folder and select Save in the bottom-right corner.

    The Image Media Type has 5 properties: Upload Image, Width, Height, Size, and Type. These are populated once the image is uploaded. The properties can be viewed in the Media section and accessed in your Templates.

    Except for the Folder Media Type, the other Media Types have 3 properties: Upload Image, Type, and Size.

    Learn more about each Media Type in the article about default Media Types.

    The default view for the Media section is a card view that lets you preview the different files that have been uploaded.

    Default grid view in the Media section

    By selecting multiple media items it is possible to perform bulk operations like moving or deleting the items.

    To edit properties on a single media item, click the name of the item, which you will see once you hover over the item.

    Edit media item

    From the top-right corner of the Media section, you can toggle between the list and grid view. There is also an option to search for the items in the Media section.

    Media Section - List view

    By adding a Media Picker property to a Document Type the editor will have the ability to select media items when creating content.

    You can create custom Media Types and control the structure of the Media tree as you would with Document Types. This means you can store information that is specific to the media on the item itself.

    A Media Type is created in the Settings section using the Media Type editor.

    1. Go to the Settings section.

    2. Click ... next to Media Types.

    3. Click Create > New Media Type.

    4. Name the new Media Type Employee Image.

    5. Choose an icon by selecting the icon left of the name field.

    You will now see the Media Type editor. It is similar to the editor used for creating Document Types.

    Creating a Media Type

    Before we start adding properties to the Media Type we need to add a group to put these in.

    1. Click on Add group.

    2. Call the group Image.

    We need to add the same properties as on the default Image Media Type. These are:

    • umbracoFile

    • umbracoWidth

    • umbracoHeight

    • umbracoBytes

    • umbracoExtension

    Follow the steps outlined below to add the properties to the Media Type:

    1. Click Add property.

    2. Name it Upload image.

    3. Change the alias to umbracoFile.

    4. Click Select property editor.

    5. Select Image cropper.

    6. Rename the editor Employee Image Cropper.

    7. Add two new crops called Thumbnail (200px x 350px) and wideThumbnail (350px x 200px).

    8. Click Save. 9. Click Add. 10. Name the remaining four properties Width, Height, Size, and Type, and give them the aliases as mentioned above. They should all use the Label editor.

    As mentioned before these properties will automatically be populated once an image has been uploaded.

    Adding properties

    Next up, we will create a folder to hold the employee images. We could use the existing Folder Media Type but that would mean editors can upload employee images to any folder of that type. If we create a folder specifically for employee images there is only one place to put them.

    1. Go back to the Settings section and create a new Media Type.

    2. Name it Employee Images.

    3. Select the folder icon by clicking the icon to the left of the name.

    4. Navigate to the Structure tab.

    5. Click Configure as a Collection under Presentation.

    6. Choose List view - Media.

    Configure Collection
    1. Click Save.

    The new folder is created under the Media Types folder. We also need to only allow the Employee Image Media Type in our new folder. Both of these configurations can be set on the Structure tab.

    1. Go to the Structure tab of the Employee Images folder.

    2. Toggle the Allow at root.

    3. Click Choose in the Allowed Child Node Types.

    4. Select Employee Image.

    5. Click Choose.

    Permissions
    1. Go to the Media section.

    2. Select ... next to Media.

    3. Click Create > Employee Images folder.

    Employee Images
    1. Name it Employee Images.

    2. Click Save.

    If you select an image that has been uploaded to the folder you will see the full image and the two defined crops.

    Moving the focal point circle on the image will update the crops to focus accordingly. You can also edit the individual crops by selecting them and moving the image or adjusting the slider to zoom.

    Login

    In this article you can learn the various ways of customizing the Umbraco backoffice login screen and form.

    To access the backoffice, you will need to login. You can do this by adding /umbraco at the end of your website URL, for example http://mywebsite.com/umbraco.

    You will be presented with a login form similar to this:

    Login screen

    The login screen contains a short greeting, a login form and an optional Forgotten password link.

    Below, you will find instructions on how to customize the login screen.

    Greeting

    The login screen features a greeting text: The "Welcome" headline. This can be personalized by overriding the existing language translation keys.

    1. Register a 'localization' manifest for the default language of your Umbraco site (default: en-US).

    2. Provide the new strings inline under meta.localizations:

    Adding the code above will override the default greetings with the ones you provide. The login screen will now display "Happy super Sunday" on Sundays instead of "Welcome".

    You can customize other text on the login screen as well. Grab the default values and keys from the dictionary in the Umbraco CMS GitHub repository — look under the login group. Then copy the ones you want to translate into your en-us.js file.

    The Forgotten password? link allows your backoffice users to reset their password. To use this feature, you will need to add the following key to the Umbraco.Cms.Security section in the appsettings.json file:

    Set it to true to enable the password reset feature, and false to disable the feature.

    You will also need to configure a Simple Mail Transfer Protocol (SMTP) server in your appsettings.json file. When you get a successful result on the SMTP configuration when running a health check in the backoffice, you are good to go!

    An example:

    It is possible to customize the background image and the logo for the backoffice login screen by adding the "Content" section in the appsettings.json file:

    The LoginBackgroundImage, LoginLogoImage, and LoginLogoImageAlternative are referenced from the /wwwroot/umbraco/ folder.

    The LoginLogoImage is displayed on top of the LoginBackgroundImage and the LoginLogoImageAlternative is displayed when the LoginLogoImage is not available, for example on small resolutions.

    You can also customize the login screen by adding a custom CSS file. To do this, you will need to add a new file inside the ~/App_Plugins folder, for example ~/App_Plugins/Login/my-custom-login-screen.css.

    You can then add your custom CSS to the file:

    This will change the color of the SVG graphics (curves) shown on the login screen. You can also hide the curves by adding the following CSS:

    To tell Umbraco about your custom CSS file, you will need to add a umbraco-package.json file. The umbraco-package.json file should look like this:

    Next add a JavaScript file, for example ~/App_Plugins/Login/my-custom-login-screen.js, and add the following code to load the custom CSS file:

    This will load the custom CSS file into Umbraco.

    The following CSS properties are available for customization:

    CSS Property
    Description
    Default Value

    The CSS custom properties may change in future versions of Umbraco. You can always find the latest values in the in the Umbraco CMS GitHub repository.

    The time out screen is displayed when the user has been inactive for a certain amount of time. The screen resembles the login screen in many ways and the two are sometimes confused. The most notable difference is that the time out screen does not have a login form. It only has a message and a button to log in again with Umbraco.

    If you have added more than one login provider, the users will also see this screen first. This is because they need to choose which provider to use first. In that case, the screen is also referred to as the Choose provider screen.

    You can customize the timeout screen in the same way as the login screen. Both screens share the same backoffice localization dictionary. The login.* keys you override for the login screen automatically apply to the timeout screen as well.

    The greeting on the time out screen uses the same login.greeting0..6 and login.instruction keys as the login screen — override them as shown in the section above. The instruction key is shown when the user has timed out, and the greeting0..6 keys are shown when the user has to choose a login provider.

    You can update the image on the time out screen through a custom CSS variable. The default value is --umb-login-image and it is set to the same value as the login screen. You can override this value in your custom CSS file:

    Upgrade Your Project

    Describes how to upgrade existing installations to new versions.

    In this article, you will find everything you need to upgrade your Umbraco CMS project.

    If you are new to upgrades, be sure to read the upgrade introduction article first.

    • Upgrade to a new Major

    • Upgrade to a new Minor

    • Legacy Umbraco

    You can upgrade to a new major version of Umbraco CMS directly by using NuGet.

    You must upgrade to the closest version before upgrading to the latest version. For Umbraco 13, the closest long-term support version is Umbraco 17. Once the project is on Umbraco 17, you can move on to Umbraco 18.

    Umbraco 18 can't upgrade from versions older than 16.4, so a project on Umbraco 13 must upgrade to Umbraco 17 first.

    Use the table below to determine which .NET version to upgrade to when going through the steps below.

    CMS version
    .NET version

    It's recommended that you upgrade the site offline and test the upgrade fully before deploying it to the production environment.

    1. Stop your site in IIS to prevent any changes from being made while you are upgrading.

    2. Open your Umbraco project in Visual Studio.

    3. Right-click on the project name in the Solution Explorer and select Properties.

    4. Select the .NET version from the Target Framework drop-down.

    1. Make sure that your connection string has TrustServerCertificate=True to complete the upgrade successfully:

    1. Restart your site in IIS, then build and run your project to finish the installation.

    If you receive an error that a deploy license is missing even though you have a valid license, follow the guide below.

    Google Chrome has aggressive caching, so when experiencing startup issues, clear the cache and cookies thoroughly. Ideally, this should be done for other browsers as well.

    Nudge the cache in Chrome following these steps:

    1. Open the developer tools (F12).

    2. Go to the settings (Cog icon).

    3. Ensure that "Disable cache (while DevTools is open)" is checked.

    4. Refresh the page, and the cache will be invalidated.

    All caches and cookies have now been cleared from your Google Chrome browser. Generally, it is a good thing to do occasionally.

    NuGet installs the latest version of the package when you use the dotnet add package command unless you specify a package version:

    dotnet add package Umbraco.Cms --version <VERSION>

    Add a package reference to your project by executing the dotnet add package Umbraco.Cms command in the directory that contains your project file.

    Run dotnet restore to install the package.

    When the command completes, open the .csproj file to make sure the package reference was updated:

    The steps outlined in this article apply to Umbraco version 10 and later versions.

    Are you upgrading to a minor version for Umbraco 6, 7, or 8? You can find the appropriate guide below:

    Installing Nightly Builds

    Instructions on installing nightly builds of Umbraco.

    Nightly builds are pre-releases and may be unstable. Do not use them in production environments.

    This article covers how to get the latest builds of Umbraco. You can do this in three steps:

    1. Adding the nightly feed as a NuGet source

    2. Finding the latest nightly version

    3. Installing the latest nightly version template

    Adding the nightly feed as a NuGet source

    The nightly builds are available on the following NuGet feed: https://www.myget.org/F/umbraconightly/api/v3/index.json.

    You can either add the feed through the command line or use an IDE of your choice.

    This article covers the following options:

    Follow these steps to add the nightly feed using the command line:

    1. Open a command prompt of your choice.

    2. Run the following command:

    Now the feed is added as a source named Umbraco Nightly.

    Follow these steps to add the nightly feed using Visual Studio:

    1. Open Visual Studio.

    2. Go to Tools > NuGet Package Manager > Package Manager Settings.

    3. Select the Package Sources option in the NuGet Package Manager section.

    4. Click the +

    Now the feed is added as a source named Umbraco Nightly.

    Follow these steps to add the nightly feed using Rider:

    1. Open Rider.

    2. Go to View > Tool Windows > NuGet.

    3. Go to Sources tab.

    4. Select the global NuGet.Config

    1. Click OK.

    Now the feed is added as a source named Umbraco Nightly.

    The next step is to identify which nightly build to install.

    However, which version do you choose? This is especially relevant when creating a new site using the dotnet template. The dotnet command does not allow for using wildcard characters to install the newest version.

    Using an IDE, you can see a list of available versions in both Visual Studio and Rider. Use these versions to install the template you need.

    The following steps apply to creating a new site using the dotnet template. The approach is the same if you're updating an existing site. You'll click the Update button for the Umbraco.Cms package instead of installing the template through the terminal.

    Find the latest version of the nightly build using either of the following options:

    Use the package manager in Visual Studio to browse the available template versions.

    1. Open Visual Studio.

    2. Go to Tools > NuGet Package Manager > Manage NuGet Packages For Solution...

    3. Select Umbraco Nightly from the Package source dropdown in the NuGet - Solution window.

    Use the NuGet window in Rider to browse the available template versions.

    1. Open Rider.

    2. Go to the Packages tab in the NuGet window.

    3. Select Umbraco Nightly from the All Feeds dropdown.

    4. Check the Prerelease checkbox.

    To install the latest nightly version template:

    1. Open the command prompt/terminal.

    2. Run the following command, replacing the version with the one you noted in the previous step:

    You can now create a site using the dotnet new umbraco -n MyAwesomeNightlySite command.

    For more information about installing Umbraco, see the article.

    Working with Rich Text Editors

    The Umbraco Rich Text Editor (RTE) is a field where you, as an editor, can be creative. You can select how much you want to do yourself. You can work on text content, format the text, or leave it the way it is. If you want to do more, you can insert images, create tables, or create links to other pages/documents.

    The functionality varies depending on how the editor is set up. Here, we describe the default editor with all the options enabled. Contact your system administrator for details regarding your editor.

    By default, the following editor buttons are available. Your system administrator can determine which buttons are displayed in different templates. You therefore might have access to more or fewer buttons than those shown here.

    The Rich Text Editor is like any other word-processing program. You write the text and the text wraps around when the line reaches the end. Use the following keyboard shortcuts in the editor to add:

    • Space between paragraphs - press ENTER

    Defining Content

    Here you'll find an explanation of how content is defined in Umbraco

    Before a piece of content can be created in the Umbraco backoffice, first it needs to be defined. That is why, when opening a blank installation of Umbraco, it is not possible to create content in the Content section.

    All content needs a blueprint that holds information about what kind of data can be stored on the content node or which editors are used.

    Additionally, it also needs information on how it is organized, where in the structure it is allowed, and so forth. This blueprint or definition is called a Document Type.

    Document Types define what kind of content can be created in the Content section and what an end-user sees and can interact with.

    It can define entire pages or more limited content that can be reused on other nodes ie. a Search Engine Optimization (SEO) group. This means that you are in complete control of what type of content can be created and where.

    Another example is if there is a "Blog post" Document Type that has some properties containing a thumbnail, a name, and an author image. Then all blog posts using the "Blog post

    Upgrade to a new Major

    Switching to a new major version of Umbraco CMS also means switching to a new .NET version. Ensure that any packages used on your site are compatible with this version before upgrading.

    The package compatibility can be checked on the package's download page. Locate the Project compatibility area and select View details to check version-specific compatibility.

    Choose the correct .NET version

    Upgrade your project using Visual Studio

    If you are upgrading a Cloud project locally from version 14 to 15, remove the Umbraco.Cloud.Cms.PublicAccess and Umbraco.Cloud.Identity.Cms packages. For more details, see Step 3: Upgrade the project locally using Visual Studio in the Umbraco Cloud Documentation.

    If you have other packages like Umbraco Forms or Deploy installed, upgrade them before upgrading Umbraco.CMS. Consult the version-specific upgrade notes for Umbraco Forms if relevant.

    You will also need to convert your one-time-off license (.lic file) to the subscription-based model (key-based license, XXXXX-XXXXX-XXXXX-XXXXX). Learn more about the different license models in the DXP Overview documentation.

    Umbraco 13 and later versions use the Minimal Hosting Model.

    If you have added custom code to the startup.cs file, it is recommended to move that code into a Composer after upgrading.

    If your database experiences timeout issues after an upgrade, it might be due to the ASP.NET Core Module's startupTimeLimit configuration.

    To fix the issue, try increasing the startupTimeLimit in the web.config file. Additionally, you can set the Connection Timeout value in the ConnectionString in the appsettings.json file.

    It is necessary to run the upgrade installer on each environment of your Umbraco site. This wil occur on first boot of an upgraded project as it is deployed into a new environment.

    Potential issues and gotchas

    Upgrade to a new Minor

    For Umbraco 9 If you are using SQL CE in your project, you need to run dotnet add package Umbraco.Cms.SqlCe --version <VERSION> before the dotnet restore command. From Umbraco 10, SQL CE has been replaced with SQLite, so a dotnet restore should be sufficient. If this is not working, then you need to run dotnet add package Umbraco.Cms.Persistence.Sqlite --version <VERSION> , and then dotnet restore.

    For larger overrides, declare the strings in a separate JavaScript file referenced from the manifest (for example /App_Plugins/Login/en-us.js). The file should export a default object with the same { group: { key: value } } shape.

    culture must match the active UI locale. The default is en-US (GlobalSettings.DefaultUILanguage), so on a default install your override extension must declare culture: "en-US" to affect the login screen. The keys themselves live in the canonical en.ts dictionary under the login group, but that does not change which override file is selected at runtime. An override declared with culture: "en" only applies when en is the active locale, or if locale fallback resolution uses it; it does not replace an active en-US override.

    Renamed: auth.* → login.*. The login screen previously had its own dictionary under an auth group (auth.greeting0, auth.instruction, …). It now reuses the shared backoffice dictionary, with keys moved to a login group. Existing translation packages that still ship with auth.greeting* overrides will continue to work through version 19, with a deprecation warning in the console. The legacy fallback will eventually be removed. New packages should target login.* directly.

    View Source Code

    If you are proficient in HTML, you can switch to HTML mode to create your page. You can also check the code and make minor adjustments to get the page exactly as you want.

    Certain elements such as scripts are not recognized by the HTML view of the Rich Text Editor. You can enter the scripts directly in the text view of the editor.

    Format Dropdown

    You can apply formatting via the Formats drop-down list. The Formats drop-down list provides predefined styles that can be applied to text while maintaining a consistent look and feel throughout the site.

    These styles incorporate advanced formatting functionality which can be applied to provide a different look for certain elements such as links, headings, and sub-headings. For example, you can use a format style to change a link into a call-to-action button.

    To apply pre-defined styles:

    1. Select the text you want to apply the style.

    2. Choose the style from the Format drop-down list.

    For more information on how to create styles, see the Style Menu article.

    You do not normally need to spend much time formatting text because Umbraco takes care of the formatting. However, the editor provides some options for controlling the text styles.

    Formatting Buttons

    The most familiar way to control formatting is by using the formatting buttons. With these buttons, you can apply basic formatting such as Bold, Italic, aligning text, creating bulleted and numbered lists, and applying indents.

    To apply a format using the formatting buttons:

    1. Select the text you want to apply the formatting.

    2. Click the desired format button.

    While pasting content, the original text styles are preserved which can lead to different font faces, sizes, and colors displaying on the website when viewed.

    Remove Format Button

    If you have already formatted a paragraph or selection using the formatting buttons, you can remove the formatting rule.

    To remove formatting:

    1. Select the text you want to remove the style from.

    2. Click the relevant formatting button to remove the formatting rule.

    You can also add a Remove format button in your toolbar. To add the Remove format button:

    1. Navigate to your Rich Text Editor in the Document Type.

    2. Click the cog wheel.

    3. Click Edit next to the Rich Text Editor Data Type.

    4. Select Remove format under the Toolbar Configuration.

    5. Click Submit.

    6. Click Save.

    Link Button

    The Insert/Edit Link button is used to add or update links to internal pages, external pages, media files, email links, and anchors. The process for inserting a hyperlink differs depending on the type of hyperlink you wish to create.

    To insert different types of hyperlinks, follow these steps:

    To display images on a page the images must be uploaded to your Umbraco media library.

    Many administrators set up a media library containing images that editors can use on their pages. Others allow their editor's free use of their images. The procedure for uploading an image varies slightly depending on which method your administrators have setup. Check with your system administrator for more information about this.

    Inserting a Table

    Tables are used to format information in a grid-based structure. When you insert a table, you select how many rows and columns the table should comprise of. Additionally, you can fill in some optional formatting properties. These values can be changed later, so it is not important to know exactly what your table will look like when you create it.

    When you place the mouse courser within the table, you will see three dots either horizontally or vertically placed on the edges of the table. Click these to open configuration options for that specific row or column.

    Editing an Existing Table

    To edit the table properties after creating it follow these steps:

    1. Place the mouse courser in the table.

    2. Click on the Table button in the Rich Text Editor toolbar.

    3. Select Table Properties.

    Table Properties

    Clicking on Table Properties gives you different options for modifying the table’s appearance. However, the developer of the website may have already created table styles for you so you may not need to adjust these settings.

    There are other options available for modifying cells, rows, and columns such as width, height, alignment, border, and so on.

    The Rich Text Editor in Umbraco can be configured in many different ways.

    For more information, see the Rich Text Editor Configuration article.

    Editing an Existing Table

    Configuring a Rich Text Editor

    " Document Type, will allow the end user to fill in a thumbnail, author name, and an author image.

    A Document Type contains fieldsets (or groups) where you can apply rules about where the content can be created, allowed template(s), backoffice icons, etc.

    A Document Type is created using the Document Type editor in the Settings section.

    • Go to the Settings section in the backoffice.

    • On the Document Types node click the + to bring up the Create menu.

    • Here choose Document Type with Template. This will create a new Document Type with a template. The Template can be found under Templates in the Settings section which will be assigned as the default template for the Document Type.

    Create Document Type

    You can also choose to create a Document Type without a template and create Folders to organize your Document Types. Other options are to create Compositions and Element types, which you can read more about in the Document Type Options section.

    First, we're prompted to give the Document Type a name. This first Document Type will be the root node for our content, name it "Home".

    Name the Document Type

    Having a root node lets you quickly query content as you know everything will be under the root node.

    Choosing appropriate icons for your content nodes is a good way to give editors a better overview of the content tree.

    To set an icon for the Document Type click the document icon in the top left corner. This will open the icon select dialog. Search for "Home"and select the icon. This icon will be used in the content tree.

    Home icon

    This will allow this Document Type to be created as the first content in the Content section.

    1. Go to the Structure tab

    2. Tick the Allow as root toggle

    3. Save the Document Type by clicking save in the bottom right corner.

    Allow as root

    Now that we have the Document Type in place, we can create the content.

    1. Go to the Content section

    2. Click on + next to Content.

    3. Select the "Home" Document Type. Name it "Home"

    Choose which Document to use for creating the content item
    1. Click Save and Publish.

    Create homepage

    As we haven't created our properties, all we can see on the "Home" node is the Properties tab. This tab contains the default properties that are available on all content nodes in Umbraco.

    Let's add some properties of our own.

    In order to add the option to create different content on the same Document Type, some groups and properties need to be added.

    Groups

    Groups are a way to organize and structure the properties within the content, making it more manageable. It also makes it more user-friendly for content editors when creating or editing content on a website.

    A name can be added to the group and after properties can be added.

    Properties

    Each field on a Document Type is called a property. The property is given a name, an alias (used to output the properties contained in a template), and an editor.

    The editor determines what type of data the property will store and the input method. There is a wide range of default property editors available and you can customize additional editors.

    Some editors require configuration where a configured editor is saved as a Data Type and can be reused for multiple properties and document types. These can be seen in the Settings section under Data Types.

    1. Go to the Settings section.

    2. Expand Document Types by clicking the arrow to the left.

    3. Select the "Home" Document Type.

    It is recommended to sort the properties into groups, however this is not a requirement.

    Create a group to hold the first properties for the Home Document Type:

    • Click Add group and name the group "Content".

    Creating groups

    To convert a group to a tab, see the Convert a group to a tab section in the Using Tabs article.

    Now that we have created a group we can start adding properties. Let's add a Rich Text editor to the Content group.

    1. Click the Add property link in the Content group. This opens the property settings dialog. Here you can set the metadata for each property (name, alias, description)

    2. Choose which Property Editor to use, and add validation if needed.

    3. Give the property a name. The name will be shown to the editor to make it relevant and understandable. Notice the alias is automatically generated based on the name. We'll name this "Body Text".

    Adding a property
    • Clicking Select Editor will open the Select Editor dialog. Here, you can choose between all the available editors on the Create a new Configuration tab. This will create a new configuration or already configured editors in the Available Configurations tab.

    • To make it easier to find what you need use the search field to filter by typing "Rich". Filtering will display configured properties first (under Available configurations) and all available editors under that.

    • Select the Rich Text editor under Create new. This will let you configure the editor settings - the Rich Text editor for this property.

    Choosing the Rich Text editor
    • Let's rename it to "Basic Rich Text editor" and only select the most necessary options.

      • bold

      • italic

      • alignLeft

      • alignCenter

      • link

      • umbMediaPicker

    • When you are happy with the settings click Submit.

    • Save the Document Type.

    • If you go to the Content section and click on the Home node you will now see the Contentgroup with the Body Text property.

    The description of the property is not necessary, but it´s a best practice as it guides the editor to use the property correctly. The property description supports some markdown and one custom collapse syntax:

    Now if we put it all together we get something like this:

    Markdown description example

    Next up we'll create a text page Document Type that will be used for subpages on the site.

    • Go back to the Settings section

    • Create a new Document Type

    • Name it "Text Page".

    • Add a group called "Content"

    • This time we'll add two properties:

      • First, make a property called "Summary" using the Textarea editor

      • Secondly, create a property called "Body Text" and reuse the Rich Text Editor Data Type.

    Before creating a Text Page in Content section, allow the Text Page Document Type to be created as a child node to the Home node.

    • Select the "Home" Document Type

    • Go to the Structure group.

    • Click Choose

    • Select "Text Page".

    Allow Child page
    • Go to the Content section

    • Click the menu icon (•••) next to the "Home" node

    • Select the "Text page" Document Type. We'll name the page "About us". We now have a basic content structure.

    Document Types are flexible and can be used for defining pieces of reusable content or an entire page, to act as a container or repository.

    You can export Document Types from an already existing project/installation and import them into another project/installation.

    • Go to the Settings section

    • Click ... next to the Document type

    • Select Export. When you click on the Export button, the Document Type is saved as a *.udt file.

    Exporting a Document Type

    To import a Document Type:

    • Go to the Settings section

    • Click ... next to the Document type

    • Select Import Document Type

    • Click on the Import button and browse to the Document Type you exported. The Name and Alias of the Document Type are displayed.

    • Click Import to complete the process.

    If you have multiple groups and/or properties you can order them with drag and drop or by entering a numeric sort order value. This is done by clicking Reorder.

    Adding properties

    Property Editors

    The name of the Data Type is based on the name of the Document Type, the name of the property, and the property editor. For example: Home - Body Text - Rich Text editor.

    Selecting the Mandatory toggle makes the property mandatory and the content cannot be saved if no value is entered (in this case, the Richtext editor).

    You have the option to add additional validation by selecting a predefined validation method under the Custom validation dropdown (such as email, number, or URL). Or by selecting a custom validation and adding a regular expression.

    Property descriptions

    Bold

    You can make text in the description bold by wrapping it with **

    Italic

    You can make text in the description italic by wrapping it with *

    Links

    You can make links by using the syntax:

    Note: Links will always have thetarget="_blank" set. This is currently not configurable.

    Images

    You can embed images by using this syntax:

    Collapsible description

    You can make the description collapsible by using this syntax:

    Composing

    This article covers the topic of composing in Umbraco.

    Customising the behaviour of an Umbraco Application at 'start up'. for example adding, removing, or replacing the core functionality of Umbraco or registering custom code to subscribe to notifications.

    An Umbraco application is a Composition made of many different 'collections' and single items of specific functionality/implementation logic/components (eg. UrlProviders, ContentFinders - see below for a full list). These collections are populated when the Umbraco Application starts up.

    'Composing' is the term used to describe the process of curating which pieces of functionality should be included in a particular collection. The code that implements these choices at start up is called a Composer.

    A Component is a generic wrapper for writing custom code during composition, it has two methods: Initialize() and Terminate()

    and these are executed when the Umbraco Application starts up, and when it shuts down, respectively. The functionality of a
    Component
    is identical to having a class handling both the
    UmbracoApplicationStartingNotification
    and
    UmbracoApplicationStoppingNotification
    .

    How are the collections populated? - Either by scanning the codebase for c# classes that inherit from a particular base class or implement a particular interface (typed scanned) or by being explicitly registered via a Composer.

    Umbraco setup the default set of components and collections that deliver the core 'out of the box' Umbraco behaviour. These default collections can be removed, reordered, replaced, etc. by implementing IComposer's and IComponents to customise and extend Umbraco's behaviour.

    This example shows how to create a component and a notification handler for the ContentSavingNotification, (perhaps to check for explicit words, or some custom business logic that needs to run before the content item is saved in Umbraco).

    We create a new C# class that implements IComposer and use it register our notification handler.

    This example shows a custom 'Spotify' OEmbed Provider which will allow Spotify URLs to be used via the 'embed' button in the Rich Text Editors. As the collection for OEmbedProviders is not 'typed scanned', we need to explicitly register the provider in the collection of OEmbedProviders. We create a C# class which implements IComposer and append our new Spotify OEmbedProvider to the EmbedProvidersCollection:

    See a list of collections below to determine which are 'type scanned' and which require explicit registration.

    It's an implementation of IComposer, that provides a quicker way to add a custom component to the Component's collection. Creating a C# class that inherits from ComponentComposer<YourComponentType> will automatically add YourComponentType to the collection of Components. In the example above, the SubscribeToContentServiceSavingComposer for the SubscribeToContentServiceSavingComponent could have been written more conveniently as:

    "Collections of elements", for example, the ContentFinders collection. - Collections are another concept that Umbraco uses to make things simpler, on top of DI. A collection builder builds a collection, allowing users to add and remove types before anything is registered into DI.

    Below is a list of collections with their corresponding 'collection type' and how items for this collection 'out of the box' are registered.

    This example shows how to control which Healthchecks are available to run in the Umbraco backoffice. Create a C# class which implements IComposer, the Compose method gives access to the HealthChecks collection of the Umbraco Composition - first we clear all HealthChecks from the collection, then add back in the ones we want to keep:

    Umbraco has some useful C# attributes to decorate your composer classes or Types used in collections, to give you further control on how and when your Composers will 'compose'.

    A finer-grain mechanism can then be used to refine the order of composition. Each composer can specify that it should compose before or after another composer, using the ComposeBefore and ComposeAfter attributes. For instance:

    ThisComposer will 'compose' before ThatOtherComposer.

    This attribute is used only for WeightedCollectionBuilders (see list above). It specifies an integer ordinal value for each item to be added to the weighted collection which controls their sort order. The weighting attribute is not applied to the Composers.

    This is used to hide a type from being auto-scanned/added to a collection as in some cases certain items/types may need to be added to a collection manually. For example, a Search package may make it optional whether to replace the 'backoffice search' with an ISearchableTree implementation. Type scanning would make this change automatically at start up if the custom implementation was detected via type scanning. This attribute could hide the class from the scanner.

    These attributes allow you to disable a particular implementation of a composer or class - Let's say Umbraco ships with two different ways of doing "something" (for instance, two front-end caches). Each way has its own composer, which registers all the relevant elements. Keep in mind that if both composers are detected, there will be some sort of collision. Ideally, we want to disable one of them. That can be achieved with the Disable attribute:

    When used without arguments, these attributes apply to the composer they are marking. But, and this is where it becomes interesting, they can be used with an argument to act on another component. Therefore, should a user want to replace our "something" with theirs, they would write the following code:

    But maybe they want to swap our two "something" implementations? In this case, assembly-level attributes can be used:

    The Umbraco.Cms.Core.RuntimeLevel enum contains the following values:

    BootFailed

    The runtime has failed to boot and cannot run.

    Unknown

    The level is unknown.

    Boot

    The runtime is booting.

    Install

    The runtime has detected that Umbraco is not installed at all, ie. there is no database, and is currently installing Umbraco.

    Upgrade

    The runtime has detected an Umbraco install which needed to be upgraded, and is currently upgrading Umbraco.

    Run

    The runtime has detected an up-to-date Umbraco install and is running.

    Example - Creating a Composer to listen for ContentSavingNotification

    Ordering of composers is important, the last one added can override a previously added composer! Make sure, when overriding, that your composer that is doing the overriding, is 'composing', after the composer has 'composed' the element you wish to override!

    Example of using Lazy Collections with Type Scanning

    Don't use type scanning if you can avoid it. Type scanning increases the Umbraco boot time.

    If your use case requires type scanning, ensure your interface implements IDiscoverable. This marker interface ensures that types are scanned once and then cached by Umbraco. This way, we save time by not having to re-scan for types repeatedly.

    Welcome

    The Welcome dashboard is the first dashboard in the Settings section. Like all dashboards, it has a customizable view and links to different resources for developing your Umbraco website.

    For more information about creating custom dashboards, see the Dashboards article.

    Examine Management

    The Examine Management dashboard provides an overview of the Examine functionality available directly within the Umbraco backoffice. The Umbraco backoffice allows you to view details about your Examine indexes and searchers - all in one place. You can see which fields are being indexed and rebuild the indexes if there's a problem. You can also test keywords to see what results will be returned.

    For more information about Examine Management, see the Examine Management article.

    Published Status

    The Published Status dashboard displays the status of your site in the Published Cache Status section alongside the Content and Media nodes value. The Caches section provides three options: Memory Cache, Database Cache, and Internals.

    • Memory Cache - Reloads the in-memory cache by entirely reloading it from the database cache. Use it when you think that the memory cache has not been properly refreshed.

    • Database Cache - Rebuilds the database cache that is the content of the cmsContentNu table. Use it when reloading the Memory Cache is not enough and you think that the database cache has not been properly generated.

    • Internals - Lets you trigger a NuCache snapshots collection.

    Models Builder

    Models builder is a tool that can generate a complete set of strongly-typed published content models for Umbraco. Models are available in both controllers and views. When using the Models Builder, the content cache does not return IPublishedContent objects anymore but returns strongly typed models implementing IPublishedContent.

    The Models Builder dashboard displays the following information:

    • Details on how Models Builder is configured, that is: InMemoryAuto, Nothing, SourceCodeAuto, and SourceCodeManual.

    • Provides a button to generate models (if the models mode is SourceCodeManual mode only).

    • Reports the last error (if any) that would have prevented models from being properly generated.

    For more information about Models Builder, see the article.

    Health Check

    Health Checks are used to determine the status of your Umbraco project. It is a handy list of checks to see if your Umbraco installation is configured according to best practices. It's possible to add your custom-built health checks.

    For more information about Health Checks, see the Health Check articles.

    Profiling

    You can use the built-in performance profiler to assess the performance when rendering pages. To activate the profiler for a specific page rendering, add umbDebug=true to the querystring when requesting the page.

    The Profiling dashboard provides a toggle option - Activate the profiler by default to keep the profiler active by default for all page renderings. You can use this option without having to set umbDebug=true on each page request. The toggle button sets a cookie named UMB-DEBUG in your browser, which then activates the profiler automatically.

    For more information about MiniProfiler, see the MiniProfiler section in the Testing and Debugging article.

    Telemetry Data

    The Telemetry Data dashboard is a consent screen that is used for collecting system and usage information from your installation. Here, you can see what type of data is being collected and even adjust the level of reporting. Currently, there are three levels available: Minimal, Basic, and Detailed.

    Detailed is the default option where the data sent contains:

    • Anonymized site ID, Umbraco version, and packages installed.

    • Number of: Root nodes, Content nodes, Media, Document Types, Templates, Languages, Domains, User Group, Users, Members, and Property Editors in use.

    • System information: Webserver, server OS, server framework, server OS language, and database provider.

    • Configuration settings: Modelsbuilder mode, if custom Umbraco path exists, ASP environment, and if you are in debug mode.

    Basic contains:

    • Anonymized site ID, Umbraco version, and packages installed.

    Minimal contains:

    • Anonymized site ID only

    You can see the specific data being sent on each of the levels directly in the Telemetry Data Dashboard.

    Additionally, Telemetry Data also sends anonymized, analytical data on package usage in Umbraco. Having solid data on package usage is important for both package developers and the Umbraco ecosystem.

    For more information about Package Telemetry, see the section in the Umbraco 9.2 Release Blog Post.

    The Umbraco UI works in all modern browsers:

    • Chrome (Latest)

    • Edge (Chromium)

    • Firefox (Latest)

    • Safari (Latest)

    Below you can find the minimum requirements to run Umbraco on your machine:

    • One of the

    • One of the following .NET Tools or Editors:

      • with the

    Umbraco can be installed with a SQLite or SQL Server database and configured with a . For SQL Server, , indicating a minimum supported version of SQL Server 2016.

    As Umbraco releases are aligned to the .NET release cadence, it's also aligned with Microsoft's Long-term support policy for the underlying framework. For the best experience, we would recommend that you ensure you are on the latest and supported Microsoft versions to run and host Umbraco CMS:

    • and other

    For more information, see the article in the Microsoft documentation.

    • Ability to set file permissions to include create/read/write (or better) for the user that "owns" the Application Pool for your site. This would typically be NETWORK SERVICE.

    • Umbraco's backoffice features such as preview and server events uses SignalR, which works best over WebSockets but will negotiate to Server-Sent Events/Long Polling. Some hosting setups buffer streamed responses, which can break the SSE fallback and surface as a "Could not establish a connection to the server" warning ~30s after opening preview.

    • To ensure the preferred WebSocket transport is available on Windows Server/IIS, install the WebSocket Protocol feature via Server Manager → Add Roles and Features → Web Server (IIS) → Web Server → Application Development → WebSocket Protocol

    The database account used in the connection string will need permission to read and write from tables. It will also require permission to create a schema during installs and upgrades:

    • The db_owner role has full permissions on the database.

    • To use an account with more restricted permissions, the db_datareader and db_datawriter roles will be needed for normal use to read from and write to the database. The db_ddladmin role, which can modify the database schema, is required for installs and upgrades of the CMS and/or any packages that create database tables.

    For more information on the Database-level roles, see the .

    Local Development

    When using Visual Studio as your primary Integrated Development Environment (IDE), we recommend finding and downloading the Software Development Kits (SDKs) for Visual Studio.

    Are you using Microsoft SQL as your data? The Umbraco Data Access Layer (DAL) does not support case-sensitive naming. When you use Microsoft SQL as your database, ensure that the database is created using a case-insensitive (CI) collation variant. For example, SQL_Latin1_General_CP1_CI_AS. Learn more about collation modes in the official Microsoft documentation.

    Hosting

    Recommendation requirements to run Umbraco

    You can use Umbraco Cloud to manage the hosting infrastructure. All Umbraco Cloud plans are hosted on Microsoft Azure, which gives your site a proven and solid foundation.

    17.latest to the latest version

    Upgrade from Umbraco 17 to Umbraco 18 with the steps in the Upgrade Your Project article. Before you upgrade, review the Umbraco 18 changes in the Breaking Changes Overview.

    Umbraco 18 can't upgrade from versions older than 16.4. Upgrade a project on an older version to Umbraco 17 first.

    13.latest to 17.latest

    Umbraco 18 can't upgrade from Umbraco 13. Upgrade to Umbraco 17, the latest Long-term Support (LTS) version, and then follow the steps for 17.latest to the latest version.

    Update _ViewImports.cshtml file

    In Umbraco 14, Smidge has been removed from the CMS.

    In the _ViewImports.cshtml of your project, remove the following lines:

    @addTagHelper *, Smidge
    @inject Smidge.SmidgeHelper SmidgeHelper

    Otherwise, it will cause an error on the front end.

    Update program.cs file

    Remove u.UseInstallerEndpoints(); from the program.cs file to avoid issues when running the project

    Update code using Angular JS

    Angular JS has been removed in Umbraco 14. If you have extended your Umbraco project using Angular JS, it must be updated. for more information read the documentation.

    To map your AngularJS code to the new backoffice, see the article.

    Deprecated property editors

    Nested Content and Grid Layout have been removed. We recommend rebuilding it using Block Grid for the grid layout and either Block Grid or Block List for Nested Content.

    The legacy Media Picker has been removed, use the default Media Picker.

    Macros and partial views macros removed

    Macros and partial views macros have been removed in Umbraco 14. We recommend using partial views or blocks in the Rich Text Editor (RTE).

    For more information on what has changed in Umbraco 14 read the .

    Block Editor data format has changes

    In Umbraco 15, the internal data format for has changed. This causes a content migration to run when upgrading.

    This content migration can take a while to complete on a large site, causing it to be unresponsive for the duration. To speed up the migration, it is advised to before upgrading.

    While we don't recommend this, it might be possible for you to skip the content migration. More details can be found in the article.

    10.latest to 13.latest

    It might be necessary to delete all of the bin and obj directories in each of the projects of your solution. It has been observed that Visual Studio's "Clean Solution" option is sometimes not enough.

    You can upgrade from Umbraco 10 to the latest version directly. If you choose to skip upgrading to versions 11 and 12, you will no longer receive warning messages for obsolete features. However, if you do skip these versions, any breaking changes will no longer compile.

    It is recommended that you upgrade to the closest Long-term Support (LTS) major version before upgrading to the latest version. For Umbraco 10, the closest long-term support version is Umbraco 13 so a direct upgrade is possible.

    9.latest to 10

    Important: .NET version 6.0.5 is the minimum required version for Umbraco 10 to be able to run. You can check with dotnet --list-sdks what your latest installed Software Development Kit (SDK) version is. The latest SDK version 6.0.301 includes .NET 6.0.6, while SDK version 6.0.300 includes .NET 6.0.5.

    Watch the 'Upgrading from Umbraco 9 to Umbraco 10 video tutorial' for a complete walk-through of all the steps.

    The upgrade path between Umbraco 9 and Umbraco 10 can be done directly by upgrading your project using NuGet. You will need to ensure the packages you are using are available in Umbraco 10.

    SQL CE is no longer a supported database engine

    There is no official migration path from SQL CE to another database engine.

    The following options may suit your needs:

    • Follow a community guide to migrate from a SQL CE database to SQL Server, like the

    • Setup a new database for v10 and use to transfer document types and content across.

    • Setup a new database for v10 and use a premium tool such as to copy database contents across.

    • Setup a new database for v10 and use a premium tool such as to transfer document types and content across.

    Steps to upgrade using Visual Studio

    It's recommended that you upgrade the site offline, and test the upgrade fully before deploying it to the production environment.

    1. Stop your site in IIS to prevent any changes being made to the database or filesystem while you are upgrading.

    2. Open your Umbraco 9 project in Visual Studio.

    3. Right-click on the project name in the Solution Explorer and select Properties.

    4. Select .NET 6.0 from the Target Framework drop-down.

    1. Remove the following files and folders:

      • /wwwroot/umbraco

      • /umbraco/PartialViewMacros

    To re-enable the appsettings IntelliSense, you must update your schema reference in the appsettings.json file and any other appsettings.{Environment}.json files from:

    To:

    To upgrade to Umbraco 10, your database needs to be at least on Umbraco 8.18.

    Upgrade of any publicly hosted environment

    When the upgrade is completed and tested, and prior to deploying to any publicly accessible environment, you should consider the following:

    1. Ensure you have backups for both the database and the file system.

    2. Stop the site so it is not accessible during the upgrade process.

    3. Delete the relevant folders from the filesystem prior to deploying:

      • /wwwroot/umbraco

    8.latest to 9

    There is no direct upgrade path from Umbraco 8 to Umbraco 9. It is however possible to migrate from Umbraco 8 sites to Umbraco 9 sites.

    You can reuse your content by restoring your Umbraco 8 database into a new database used for an Umbraco 9 site.

    You need to ensure the packages you are using are available in Umbraco 9, and you will need to reimplement your custom code and templates.

    The direct upgrade path is not possible because the codebase has been fundamentally updated in Umbraco 9. The underlying web framework has been updated from ASP.NET to ASP.NET Core.

    It is not possible to take this step while maintaining full compatibility with Umbraco 8.

    8.0.0 to 8.1.0

    There are a few breaking changes from 8.0.x to 8.1.0. Make sure to check the full list.

    IPublishedContent breaking changes in 8.1.0

    Due to the changes in IPublishedContent there are a few steps you will need to take, to make sure that your site works.

    The IPublishedContent interface is central to Umbraco, as it represents published content and media items at the rendering layer level. This could be in controllers or views. In other words, it is the interface that is used everywhere when building sites.

    The introduction of multilingual support in version 8 required changes to the interface. For instance, a property value could be obtained with GetPropertyValue(alias) in version 7. Version 8 requires a new parameter for culture, and the call thus became Value(alias, culture).

    In the excitement of the version 8 release, we assumed that IPublishedContent was "done". By our tests, everything was looking good. However, feedback from early testers showed that the interface was in some places odd or inconsistent or had issues.

    Fixing the bugs is a requirement. Some of the required bug fixes could not be achieved without introducing some breaking changes.

    At that point, we decided to give IPublishedContent some love. We fixed the bugs and made it clean, friendly, discoverable, and predictable for the entire life of version 8.

    Breaking changes to such a central interface is not something we take lightly. Even though they do not impact the "concepts" nor require heavy refactoring, they may demand an amount of small fixes here and there.

    The general idea underlying these changes is that:

    • The proper way to retrieve "something" from an IPublishedContent instance is always through a method, for example: Children(). And, when that method can be multilingual, the method accepts a culture parameter, which can be left null to get the "current" culture value.

    • To reduce the amount of breaking changes, and to simplify things for non-multilingual sites, existing properties such as document.Name and document.Children (and others) still exist, and return the value for the current culture. In other words, these properties are now implemented as

    The rest of this document presents each change in details.

    More interfaces

    It was possible to mock and test the IPublishedContent interface in version 7. It has been improved in version 8, but it still relies on concrete PublishedContentType and PublishedPropertyType classes to represent the content types, which complicates things.

    In version 8.1, these two classes are abstracted as IPublishedContentType and IPublishedPropertyType, thus making IPublishedContent easier to mock and test.

    CHANGE: This impacts every method accepting or returning a content type. For instance, the signature of most IPropertyValueConverter methods changes. References to PublishedContentType must be replaced with references to IPublishedContentType.

    The following IPublishedContent members change:

    Name

    The document.Name property is complemented by the document.Name(string culture = null) extension method. The property returns the name for the current culture. The document.GetCulture(...).Name syntax is removed.

    CHANGE: Calls to document.GetCulture(culture).Name must be replaced with document.Name(culture).

    UrlSegment

    The document.UrlSegment property is complemented by the document.UrlSegment(string culture = null) extension method. The property returns the Url segment for the current culture. The document.GetCulture(...).UrlSegment syntax is removed.

    CHANGE: Calls to document.GetCulture(culture).UrlSegment must be replaced with document.UrlSegment(culture).

    Culture

    The document.GetCulture() method is removed. The proper way to get a culture date is document.CultureDate(string culture = null). The document.Cultures property now returns the invariant culture, for invariant documents.

    CHANGE: Calls to document.GetCulture(culture).Date must be replaced with document.CultureDate(culture). Calls to document.Cultures must take into account the invariant culture.

    Children

    The document.Children property is complemented by the document.Children(string culture = null) extension method which, when a culture is specified always return children available for the specified culture. The property returns the children available for the current culture.

    A new document.ChildrenForAllCultures property is introduced, which returns all children, regardless of whether they are available for a culture or not.

    CHANGE: Calls to document.Children may have to be replaced by document.ChildrenForAllCultures depending on if the 8.0.x usage of this was relying on it returning unfiltered/all children regardless of the current routed culture.

    Url

    The document.Url property is complemented by the document.Url(string culture = null, UrlMode mode = UrlMode.Auto) extension method. The document.GetUrl(...) and document.UrlAbsolute() methods are removed. The UrlProviderMode enumeration is renamed UrlMode.

    CHANGE: Calls to document.GetUrl(...) must be replaced with document.Url(...). Calls to document.UrlAbsolute() must be replaced with document.Url(mode: UrlMode.Absolute).

    UmbracoContext

    Due to the UrlProviderMode enumeration being renamed UrlMode, the signature of some overloads of the Url(...) method has changed. Methods that do not have a mode parameter remain unchanged.

    CHANGE: Code such as context.Url(1234, UrlProviderMode.Absolute) must become context.Url(1234, UrlMode.Absolute).

    The UmbracoContext class gives access to the rendering layer, which is more than a "cache". To reflect this, its ContentCache and MediaCache properties are renamed Content and Media. However, the old properties remain as obsolete properties.

    CHANGE: None required in 8.1, but code such as context.ContentCache.GetById(1234) should eventually be converted to context.Content.GetById(1234) as the obsolete properties may be removed in a further release.

    GetCulture

    Version 7 had a document.GetCulture() method that was deriving a culture from domains configured in the tree. Somehow, that method was lost during version 8 development (issue ).

    Because that method is useful, especially when building traditional, non-multilingual sites, it has been re-introduced in version 8.1 as document.GetCultureFromDomains().

    CHANGE: None.

    DomainHelper

    DomainHelper has been replaced with a static DomainUtilities class.

    CHANGE: It is rare that DomainHelper is used in code since it only contains one public method but if developers are using this, it can no longer be injected since it's now a static class called DomainUtilities.

    Models Builder

    If you're using ModelsBuilder in dll mode you need to delete the dlls before upgrading. Otherwise, they're going to be wrong and cause your whole site to throw errors.

    If you're using ModelsBuilder in AppData mode and you have your generated models in your solution you need to update them after upgrading. PublishedContentType will need to be replaced with IPublishedContentType. If you have an implementation of the PropertyValueConverter class, you need to replace all references to PublishedPropertyType with IPublishedPropertyType within that class. Only after you do that will your solution build again.

    AutoMapper

    Umbraco 8.1 replaces AutoMapper with . This in itself will not break anything on your site. If you have used AutoMapper in your own code you will have to either include the package yourself or switch your implementation to use UmbracoMapper.

    7.latest to 8.0.0

    There is no direct upgrade path from Umbraco 7 to Umbraco 8. It is however possible to migrate content from Umbraco 7 sites to Umbraco 8 sites. We have added content migrations in Umbraco 8.1.0 enabling you to migrate your content from Umbraco 7 to Umbraco 8.

    It is not possible to upgrade an Umbraco 7 site to Umbraco 8 because the codebase has been fundamentally updated in Umbraco 8. A lot of outdated code and technology has been removed and instead new, faster, and more secure technology has been implemented.

    In Umbraco 8 we have added improvements and updated dependencies. We have also done a thorough clean-up to make it simpler for you to work with and extend your Umbraco project.

    Migrate your content to Umbraco 8

    7.6.3 to 7.7.0

    Version 7.7.0 introduces User Groups, better user management, and security facilities. This means that anything to do with "User Types" no longer exists including APIs that work with User Types. If your code or any package's code refers to "User Type" APIs, you need to make changes to your code. In many cases, we've added backward compatibility for these scenarios and obsoleted APIs that should no longer be used.

    We are now by default using the e-mail address and not the username for the credentials. When trying to login to the backoffice you need to use the e-mail address as opposed to the username. If you do an upgrade from an older version and would like to keep using the username, change the <usernameIsEmail>true</usernameIsEmail> setting to false.

    For a full list of breaking changes see: the list on the issue tracker

    Version 7.7.2 no longer ships with the CookComputing.XmlRpcV2 assembly. If you reference this assembly or have a package that requires this assembly, you need to copy it back into your website.

    This version also ships with far fewer client files that were only relevant for older versions of Umbraco (i.e. < 7.0.0). There might be some packages that were referencing these old client files. If you see missing image references you may need to contact the vendor of the package in question to update their references.

    Follow the to complete the upgrade.

    7.6.0 to 7.6.3

    In short:

    In Umbraco version 7.6.2 we made a mistake in the Property Value Converts (PVCs). This was corrected 2 days later in version 7.6.3. If you were having problems with querying the following Data Types on the frontend, make sure to upgrade to 7.6.3:

    • Multi Node Tree Picker

    • Related Links

    • Member Picker

    Depending on whether you tried to fix the problem with those, you will need to fix them after you upgrade to 7.6.3.

    Property Value Converters (PVC)

    Umbraco stores data for Data Types in different ways. For a lot of pickers it will store 1072 or 1083,1283. These numbers refer to the identifier of the item in Umbraco. In the past, when building your templates, you would manually have to take that value and find the content item it belongs to. Then you would be able to get the data you wanted from there. An example of that is shown below:

    In Umbraco 7.6.0, this is what you would do instead:

    This is possible using Models Builder and through the inclusion of , a package by community member Jeavon Leopold.

    To not break everybody's sites (the results of queries are different when PVCs are enabled), we disabled these PVCs by default.

    Umbraco 7.6.0 also came with new pickers that store their data as a . We wanted to simplify the use of these new pickers and by default we wanted PVC's to always be enabled for those pickers.

    We noticed that some new pickers also got their PVC's disabled when the configuration setting was set to false (<EnablePropertyValueConverters>false</EnablePropertyValueConverters>).

    To make everything consistent, we made sure that the UDI pickers would always use PVC's in 7.6.2, this however reversed the behavior. So when PVC's were enabled, the property would not be converted and when PVC's were disabled, the property would be converted after all. This is the exact opposite behavior of 7.6.2.

    So we have fixed this now in 7.6.3.

    This issue only affects:

    • Multi Node Tree Picker

    • Related Links

    • Member Picker

    Have you already upgraded to 7.6.2 and fixed queries for those three Data Types? Then you have to do that again in version 7.6.3.

    Follow the to complete the upgrade.

    7.4.0 to 7.6.0

    Find a list of all the breaking changes below and a list of the items is also available on the tracker

    The three most important things to note are:

    1. In web.config do not change useLegacyEncoding to false if it is currently set to true - changing the password encoding will cause you not being able to log in any more.

    2. In umbracoSettings.config leave EnablePropertyValueConverters set to false - this will help your existing content queries to still work.

    3. In tinyMceConfig.config make sure to remove <plugin loadOnFrontend="true">umbracolink</plugin> so that the rich text editor works as it should.

    Breaking Changes

    Dependencies

    UrlRewriting.Net ()

    UrlRewriting was old, leaking memory, and slowing down website startup when dealing with more than a few rules. It's entirely replaced by the extension.

    Json.Net ()

    Json.Net has been updated to version 10.0.0 to benefit from improvements in features, fixes, and performances (see ). This might be a breaking change for people relying on one of the changed functionality.

    Log4net ()

    Umbraco has used a custom build of an old (1.2.11) version of log4net that supported Medium Trust. However, Umbraco itself does not support Medium Trust anymore, and therefore log4net has been upgraded to the standard, latest build of log4net 2.0.8.

    ImageProcessor ()

    An optional parameter has been added to the GetCropUrl method in order to support the background color parameter. This breaks the method signature and therefore might require a recompile of user's code.

    HtmlAgilityPack ()

    The HtmlAgilityPack has been upgraded to version 1.4.9.5. The Umbraco upgrade process should take care of setting up the binding redirects appropriately.

    Core

    Membership Provider Encoding ()

    The Membership Provider useLegacyEncoding setting is now false by default, as the legacy password encoding has weaknesses.

    This change only impacts new installs (no change for upgrades).

    Property Value Converters ()

    A large amount of property value converters contributed by the community have been merged in and are now the default value converters. These converters change the object types returned by GetPropertyValue for more convenient types.

    Instead of returning comma-separated string values like it did before, the SliderValueConverter now returns a decimal or a Range<decimal> value that can be used directly in views.

    This change only impacts new installs (no change for upgrades).

    The new property value converters are controlled by an umbracoSettings.config setting. In the section settings/content, setting EnablePropertyValueConverters needs to be present and true to activate them.

    Database ()

    Umbraco has been using a PetaPoco-managed UmbracoDatabase instance since version 7 came out. We realized that some of our legacy code still bypassed that mechanism and used parallel, out-of-band database connections, causing issues with transactions.

    The legacy code has been refactored to rely on the UmbracoDatabase instance. However, because that database is disposed of during EndRequest, the code that ran after it has been disposed may not work anymore. This should then be updated to use either an HttpModule event that occurs before EndRequest or the new UmbracoModule.EndRequest event.

    More details are available on on the 301 Redirect Tracker GitHub issue tracker.

    Scopes ()

    Version 7.6 introduces the notion of scopes, which allow for wrapping multiple service-level operations in one single transaction. The scopes API is partially public. Scopes are not meant for public use at this stage and we need a few more releases to ensure that the APIs are stable.

    Scopes should not change how Umbraco functions.

    Introducing scopes means that some public APIs signatures are changing. Most of these changes target internal and/or non-breaking APIs (as per our ). This should therefore have no impact on sites but may break unit tests.

    Property Editors storing UDI instead of ID ()

    The property editors for pickers for content, media, members, and related links have been updated to store UDI instead of the node ID. Pickers in sites being upgraded have been marked as obsolete but will continue to work as they always did.

    New sites will have the obsolete pickers filtered out from the list of available property editors, but they can be enabled by a configuration flag.

    Rich Text Editor (RTE) Images attributes (, )

    For a long time, we had a rel attribute on an <img> tag when inserted into the RTE. This is invalid HTML markup. We worked around this by stripping this attribute using a Property Editor Value converter. Some developers relied on this attribute so we didn't change it to a "data-id" attribute which would have been valid. In 7.6 we are not storing integer IDs in these attributes. Instead of storing UDI values so with this change we no longer use rel or data-id and instead there will be a "data-udi" attribute. This change should affect only a small amount of people that were previously relying on the values from the "rel" attribute.

    Others

    We are shipping with SignalR in the core at version 2.2.1. If you already have SignalR installed into your app and are using an older version there may be conflicts.

    The creation and editing of WebForms templates will no longer be supported as for version 7.6.0.

    Upgrading via NuGet

    This is an important one and there was no perfect solution to this. We have removed the UrlRewriting dependency and no longer ship with it. However, if you are using it we didn't want to have NuGet delete all of your rewrites. The good news is that if you are using it, the NuGet upgrade will not delete your rewrite file and everything should continue to work.

    However, if you are not using it, you will get an error after upgrading. Here's how to fix it:

    Since you aren't using UrlRewriting you will have probably never edited the UrlRewriting file. In this case, NuGet will detect that and remove it. However you will need to manually remove these UrlRewriting references from your web.config:

    and

    Remove the following httpModules from your web.config:

    and

    Forms

    Umbraco Forms 6.0.0 has been released to be compatible with Umbraco 7.6. It is a new major version release of Forms primarily due to the strict dependency on 7.6+. If you are using Forms, you will need to update it to version 6.0.0

    There are .

    Courier

    Umbraco Courier 3.1.0 has been released to be compatible with Umbraco 7.6. If you are using Courier, you will need to update it to version 3.1.0.

    7.3.0 to 7.4.0

    For manual upgrades:

    • Copy the new folder ~/App_Plugins/ModelsBuilder into the site

    • Do not forget to merge ~/Config/trees.config and ~/Config/Dashboard.config - they contain new and updated entries that are required to be there

      • If you forget trees.config you will either not be able to browse the Developer section or you will be logged out immediately when trying to go to the developer section

    • You may experience an error saying Invalid object name 'umbracoUser' - this can be fixed by

    7.2.0 to 7.3.0

    Make sure to manually clear your cookies after updating all the files, otherwise you might an error relating to Umbraco.Core.Security.UmbracoBackOfficeIdentity.AddUserDataClaims(). The error looks like: Value cannot be null. Parameter name: value.

    NuGet will do the following for you. If you're upgrading manually make sure to also:

    • Delete bin/Microsoft.Web.Helpers.dll

    • Delete bin/Microsoft.Web.Mvc.FixedDisplayModes.dll

    • Delete bin/System.Net.Http.dll

    • Delete bin/System.Net.Http.*.dll (all dll files starting with System.Net.Http) except for System.Net.Http.Formatting.dll

    • Delete bin/umbraco.XmlSerializers.dll

    • Add this in the appSetting section of your web.config file: <add key="owin:appStartup" value="UmbracoDefaultOwinStartup" />

    .NET Core CLI

    Go to Tools > NuGet Package Manager > Manage NuGet Packages for Solution...

  • Go to the Installed tab in the NuGet Package manager.

  • Choose Umbraco.Cms.

  • Select 10.0.0 from the Version drop-down and click Install to upgrade your project to version 10.

  • Update Program.cs to the following:

  • /umbraco/UmbracoBackOffice
  • /umbraco/UmbracoInstall

  • /umbraco/UmbracoWebsite

  • /umbraco/config/lang

  • /umbraco/config/appsettings-schema.json

  • If using Umbraco Forms, update your files and folders according to the Upgrading - version specific for version 10 article.

  • Restart your site in IIS, build and run your project to finish the installation of Umbraco 10.

  • /umbraco/PartialViewMacros

  • /umbraco/UmbracoBackOffice

  • /umbraco/UmbracoInstall

  • /umbraco/UmbracoWebsite

  • /umbraco/config/lang

  • /umbraco/config/appsettings-schema.json

  • If you are using Umbraco Forms, update your files and folders according to the Upgrading - version specific for version 10 article.

  • Deploy the site how you normally would to your public facing environment.

  • Start the site. At this point it will launch and upgrade the database, after which the site should become accessible and your upgrade is complete.

  • Check the logs for any errors which may have occurred during the upgrade process.

  • document.Name => document.Name()
    or
    document.Children => document.Children()
    .
    ~/web.config
    file in the release
  • MVC has been updated to MVC5

    • You need to update your web.config file to have the correct MVC version references - this should be done by doing a compare/merge of your ~/web.config file with the ~/web.config file in the release

    • The upgrader will take care of updating all other web.config’s (in all other folders, for example, the Views and App_Plugins folders) to have the correct settings

    • For general ASP.NET MVC 5 upgrade details see:

  • It is not required that you merge the changes for the Examine index paths in the ExamineIndex.config file. However, if you do, your indexes will be rebuilt on startup because Examine will detect that they don’t exist at the new location.

  • It's highly recommended to clear the browser cache - the ClientDependency version is automatically bumped during installation which should force the browser cache to refresh, however in some edge cases this might not be enough.

  • /config/AppSettings.config and /config/ConnectionString.config can be removed after the contents have been moved back to web.config.

    Migrate Backoffice Extensions from AngularJS

    Map the AngularJS concepts from Umbraco 13 backoffice extensions to Web Components, contexts, and the Umbraco HTTP Client in Umbraco 14 and later.

    This article is for developers who built backoffice extensions with AngularJS in Umbraco 13 or earlier. Examples are dashboards, property editors, and Content Apps.

    Umbraco 14 replaced the AngularJS backoffice with a new backoffice built on Web Components. AngularJS code does not run in the new backoffice, so you rebuild each extension. Most AngularJS concepts have a direct equivalent.

    This article maps those concepts and ports a small dashboard as an example. For the server side of your extension, see the Porting old Umbraco API Controllers article.

    Quick Reference

    Umbraco 13 (AngularJS)
    Umbraco 14 and later

    The rest of this article ports a dashboard that lists, adds, and deletes items. It calls the API controller from the tutorial.

    In Umbraco 13, the same API was an UmbracoAuthorizedApiController named MyItemApiController. Umbraco routed its actions to /umbraco/backoffice/api/MyItemApi/{action} by convention.

    AngularJS extensions were often plain JavaScript files in App_Plugins, without a build step. You can still write plain JavaScript modules.

    The sets up TypeScript, a Vite build, and the backoffice types for you. With the --include-example option, it also adds an example dashboard and API controller.

    In Umbraco 13, a package.manifest file lists dashboards and the JavaScript files to load:

    A language file next to it held the texts, including the label of the dashboard tab:

    In Umbraco 14 and later, an umbraco-package.json file lists the extensions. Each extension has a type and points to the code it loads.

    The manifest changes in these ways:

    • The sections array becomes a condition. Section aliases now have the Umb.Section. prefix, so member becomes Umb.Section.Members. To show a dashboard in one section, use match with a single alias instead of oneOf.

    • The dashboard loads a JavaScript module instead of an HTML view and a controller.

    To show a dashboard first, give it a higher weight than the built-in dashboards of the section. The article lists their weights and the section aliases.

    In Umbraco 13, an AngularJS controller holds the state and the logic:

    An HTML view rendered the state:

    In Umbraco 14 and later, one Web Component holds the state, the logic, and the markup. The following Lit element replaces both files:

    Compile the element to App_Plugins/MyItems/my-items-dashboard.js, the file that the manifest points to. The Umbraco Extension Template compiles it for you. Without the template, see the article.

    The element is the default export of the module, so the manifest needs no elementName.

    Styles live in the element's static styles. The element renders into a Shadow DOM, so stylesheets on the page do not reach it.

    To build a dashboard step by step, follow the tutorial.

    Lit templates are JavaScript template literals. The following table maps the AngularJS directives to Lit:

    AngularJS
    Lit

    The prefix on a binding decides what it sets. A . sets a property, a ? toggles a Boolean attribute, and an @ adds an event listener. Lit has no two-way binding, so you listen for input events and update the state yourself.

    Import the directives from @umbraco-cms/backoffice/external/lit. For more about expressions, see the .

    AngularJS injects services into a controller by parameter name. In the new backoffice, an element asks for a context with consumeContext(). The callback runs when the context is available.

    Umbraco 13 service
    Umbraco 14 and later

    A few of these work differently:

    • this.localize.term() returns the text right away. localizationService.localize() returned a promise.

    • umbConfirmModal() returns a promise. The promise resolves when the user confirms, and rejects when the user cancels.

    • Many contexts expose observables instead of promises. Use this.observe() to read the value when it arrives and each time it changes.

    The following element replaces a call to userService.getCurrentUser():

    Observers stop when the element leaves the page. You do not need to clean them up, as you did with $scope.$on('$destroy').

    For more about contexts, see the article.

    In Umbraco 13, you call an API controller with $http, and umbRequestHelper.resourcePromise unwraps the response:

    In Umbraco 14 and later, use the Umbraco HTTP Client and wrap the call in tryExecute, as the dashboard example does:

    The differences from $http are:

    • URLs: The route of the controller and the HTTP method replace the action name in the URL, and IDs move into the path. Write the full path, starting with /umbraco.

    • Property names: The Management API returns camelCase property names. UmbracoAuthorizedApiController returned the C# names, so data.Items becomes data.items.

    Responses with status 401, 403, or 404 do not show a notification. Check the returned error and handle these responses in your code. For the full rules, see the article.

    If your API has an OpenAPI document, you can generate a typed client instead. The Umbraco Extension Template sets up a generated client for you. For details, see the article.

    In Umbraco 13, a ServerVariablesParsingNotification handler adds values to the global Umbraco.Sys.ServerVariables object. Umbraco 14 and later have no server variables.

    Before you move a value over, check whether your extension needs it. Often the client can work without values from the server.

    If your extension needs a value from the server, return it from a config endpoint on your API controller. The endpoint returns only the values your extension needs, instead of adding them to a global object on every backoffice page. Only signed-in backoffice users can call it by default, and you can restrict it further with the of the Management API.

    The following controller returns how many items the dashboard shows. It reads the value from the MyItems:PageSize setting in appsettings.json:

    The element reads the value with the Umbraco HTTP Client. The Management API returns camelCase property names, so PageSize becomes pageSize:

    AngularJS wraps promises and timers in $q and $timeout, so that the view is updated afterward. The new backoffice uses the standard JavaScript APIs:

    AngularJS
    Umbraco 14 and later

    Lit has no digest cycle. An element renders again when a @state() or @property() value changes. Lit compares the old and the new value, so changing an item inside an array is not a change. Assign a new array or object to render again.

    Property editors follow the same patterns, with a few additions:

    • $scope.model.value becomes the value property of the element. Dispatch an UmbChangeEvent when the value changes.

    • $scope.model.config becomes the config property. Read a setting with config.getValueByAlias().

    Umbraco migrates your existing Data Types when you upgrade. The migration depends on how you registered the property editor. For details, see the article.

    To build a property editor step by step, follow the tutorial.

    The Lang/en-US.xml file becomes a localization extension. Each area becomes an object with a property for each key, so myItems_headline keeps working.

  • The tab label moves from the dashboardTabs_myItemsDashboard key to meta.label.

  • The weight sorts the other way. In Umbraco 13, the lowest weight came first. Now the highest weight comes first, so -10 moves the dashboard from the first tab to the last.

  • Authentication: $http sent the backoffice cookie. The Management API uses access tokens instead. The security array tells the Umbraco HTTP Client to add the token of the current user.
  • Sessions: The Umbraco HTTP Client refreshes an expired token. When the session has expired, it asks the user to log in again.

  • Errors: resourcePromise shows a notification only for server errors, and passes other failures to your rejection handler. tryExecute returns an object with data and error instead of a rejected promise. When the request fails, it shows a notification with the title and detail from the problem details in the response.

  • Types: The type argument maps the status code to the response type, so data has the right type.

  • Parameters: Pass query string parameters in query, and a request body in body.

  • The prevalues in package.manifest become settings in the meta of the propertyEditorUi extension.

    Block Grid

    Schema Alias: Umbraco.BlockGrid

    UI Alias: Umb.PropertyEditorUi.BlockGrid

    Returns: BlockGridModel

    The Block Grid property editor enables editors to layout their content in the Umbraco backoffice. The content is made of Blocks that can contain different types of data.

    Configuring the Block Grid

    The Block Grid property editor is configured via the Data Types backoffice interface.

    To set up the Block Grid property editor, follow these steps:

    1. Navigate to the Settings section in the Umbraco backoffice.

    2. Click ... next to the Data Types folder.

    3. Select Create -> Data Type.

    4. Select Block Grid from the list of available property editors.

    You will see the configuration options as shown below:

    The Data Type editor allows you to configure the following properties:

    • Blocks - Defines the Block Types available for use in the property. For more information, see . Blocks can also be grouped. This is then visible to editors in the Block Catalogue when populating content, and can also be used to allow a group of Blocks in an Area.

    • Amount - Sets the minimum and/or the maximum number of Blocks that should be allowed at the root of the layout.

    • Live editing mode - Enabling this option will allow you to see the changes as you are editing them.

    Block Types are based on . These can be created beforehand or while setting up your Block Types.

    Once you have added an Element Type as a Block Type on your Block Grid Data Type you have the option to configure it.

    Each Block has a set of properties that are optional to configure. These are described below.

    Customize the user experience for your content editors when they work with the Blocks in the Content section.

    • Label - Defines a label for the appearance of the Block in the editor. The label can use to display values of properties. The label is also used for search in the Add Block dialog during content editing. If no label is defined, the block will not be searchable. The search does not fall back to the block’s name.

    • Content model - Presents the Element Type used as model for the Content section of this Block. This cannot be changed but you can open the Element Type to perform edits or view the properties available. Useful when writing your Label.

    • Settings model - Adds a Settings section to your Block based on a given Element Type. When selected you can open the Element Type or choose to remove the Settings section again.

    • Allow in root - Determines whether the Block can be created at the root of your layout. Turn this off if you only want a Block to appear within Block Areas.

    • Allow in areas - Determines whether the Block can be created inside Areas of other Blocks. If this is turned off it can still be allowed in Block Areas by defining specific allowed Blocks.

    Customize the Blocks size in the Grid. If you define multiple options, the Block becomes scalable.

    By default, a Block takes up the available width.

    A Block can be resized in two ways:

    1. When a Block is placed in an Area, it will fit to the Areas width. Learn more about .

    2. A Block can have one or more Column Span options defined.

    A Column Span option is used to define the width of a Block. With multiple Column Span options defined, the Content Editor can scale the Block to fit specific needs.

    Additionally, Blocks can be configured to span rows, this enables one Block to be placed next to a few rows containing other Blocks.

    • Available column spans - Defines one or more columns, the Block spans across. For example: in a 12 columns grid, 6 columns is equivalent to half width. By enabling 6 columns and 12 columns, the Block can be scaled to either half width or full width.

    • Available row spans - Defines the amount of rows the Block spans across.

    See the section of this article for an example of how scaling works.

    Blocks can nest other Blocks to support specific compositions. These compositions can be used as a layout for other Blocks.

    To achieve nesting, a Block must have one or more Areas defined. Each Area can contain one or more Blocks.

    Each Area has a size, defined by column and rows spans. The grid for the Areas are based on the same amount of columns as your root grid, unless you choose to change it.

    To scale an Area, click and drag the scale-button in the bottom-right corner of an Area.

    • Grid Columns for Areas - Overwrites the amount of columns used for the Area grid.

    • Areas - Determines whether the Block can be created inside Areas of other Blocks.

    • Alias - The alias is used to identify this Area. It is being printed by GetBlockGridHTML() and used as name for the Area slot in Custom Views. The alias is also available for CSS Selectors to target the HTML-Element representing an Area.

    • Create Button Label - Overwrites the Create Button Label of the Area.

    • Number of blocks - Determines the total number of Blocks in an Area.

    When allowing a group of Blocks, you might want to require a specific amount for a certain Block of that group. This can be done by adding that Block Type to the list as well, and setting the requirements accordingly.

    Advanced properties are also available for each Block, as shown below.

    • Overlay editor size - Sets the size for the Content editor overlay for editing this block.

    • Inline editing - Enabling this will change editing experience to inline, meaning that editing the data of blocks happens at sight as accordions.

    • Hide content editor - Hides the UI for editing the content in a Block Editor. This is only relevant if you made a custom view that provides the UI for editing of content.

    • Custom view - Overwrites the view for the block presentation in the Content editor. Building Custom Views for Block representations in Backoffice is the same for all Block Editors.

    These properties refer to how the Block is presented in the Block catalogue, when editors choose which Blocks to use for their content.

    • Background color - Define a background color to be displayed beneath the icon or thumbnail. Eg. #424242.

    • Icon color - Change the color of the Element Type icon. Eg. #242424.

    • Thumbnail - Pick an image or SVG file to replace the icon of this Block in the catalogue.

    The thumbnails for the catalogue are displayed at a maximum height of 150px and will scale proportionally to maintain their original aspect ratio. Any standard image format (PNG, JPG, SVG) will work effectively.

    When viewing a Block Grid property editor in the Content section for the first time, you will be presented with the option to Add content.

    Clicking the Add content button opens up the Block Catalogue.

    The Block Catalogue looks different depending on the amount of available Blocks and their catalogue appearance.

    Click the Block Type you wish to create and a new Block will appear in the layout.

    More Blocks can be added to the layout by clicking the Add content button. Alternatively, use the Add content button that appears on hover to add new Blocks between, besides, or above the existing Blocks.

    To delete a Block, click the trash icon which appears on the mouse hover.

    Blocks can be rearranged using the click and drag feature. Move them up or down to place them in the desired order.

    Moving a Block from one Area to another is done in the same way. If a Block is not allowed in the given position, the area will display a red color and not allow the new position.

    If a Block has multiple size options it can be scaled via the UI. This appears in the bottom-right corner of the Block.

    The Block is resized using a click-and-drag feature. Moving the mouse will change the size to the size options closest to the mouse pointer.

    Rendering the stored value of your Block Grid property editor can be done in two ways:

    You can choose to use the built-in rendering mechanism for rendering Blocks using a Partial View for each block.

    The default rendering method is named GetBlockGridHtmlAsync() and comes with a few options - for example:

    In the sample above "myGrid" is the alias of the Block Grid editor.

    If you are using ModelsBuilder, the example will look like this:

    To use the GetBlockGridHtmlAsync() method, you will need to create a Partial View for each Block Type. The Partial View must be named using the alias of the Element Type that is being used as Content Model for the Block Type.

    These Partial View files need to go into the Views/Partials/blockgrid/Components/ folder.

    Example: Views/Partials/blockgrid/Components/MyElementTypeAliasOfContent.cshtml.

    The Partial Views will receive a model of type Umbraco.Cms.Core.Models.Blocks.BlockGridItem. This model contains Content and Settings from your block, as well as the configured RowSpan, ColumnSpan, and Areas of the Block.

    The Partial View for the Block is responsible for rendering its own Block Areas. This is done using another built-in rendering mechanism:

    Here you will need to create a Partial View for each Block Type within the Block Area. For the name, use the alias of the Element Type that is being used as Content Model for the Block Type.

    These Partial Views must be placed in the same folder as before, (Views/Partials/blockgrid/Components/), and will receive a model of type Umbraco.Cms.Core.Models.Blocks.BlockGridItem.

    The following is an example of a Partial View for a Block Type of type MyElementTypeAliasOfContent.

    If you are using ModelsBuilder, you can make the property rendering strongly typed by letting your view accept a model of type BlockGridItem<T>. For example:

    Using the default rendering together with your layout stylesheet will provide what you need for rendering the layout.

    To use the Default Layout Stylesheet, copy the stylesheet to your frontend. You can download the default layout stylesheet from the link within the DataType, we recommend putting the file in the css folder, example: wwwroot/css/umbraco-blockgridlayout.css.

    The built-in value converter for the Block Grid property editor lets you use the block data as you like. Call the Value<T> method with a type of BlockGridModel to have the stored value returned as a BlockGridModel instance.

    BlockGridModel contains the Block Grid configuration (like the number of columns as GridColumns) whilst also being an implementation of IEnumerable<BlockGridItem> (see details for BlockGridItem above).

    The following example mimics the built-in rendering mechanism for rendering Blocks using Partial Views:

    If you do not want to use Partial Views, you can access the block item data directly within your rendering:

    When using Block Grid in a headless scenario with the , the property outputs a structured JSON representation instead of rendered HTML.

    The JSON structure includes:

    • gridColumns - The number of columns configured for the grid (typically 12)

    • items - An array of block items, each containing:

      • content - The block's content data

    Your frontend application is responsible for:

    • Parsing the grid layout structure

    • Implementing CSS Grid or an equivalent layout system

    • Rendering blocks recursively to handle nested areas

    • Handling responsive behavior

    For detailed information about the JSON structure and property expansion options, see .

    The default layout stylesheet is using CSS Grid. This can be modified to fit your implementation and your project.

    To make additions or overwrite parts of the default layout stylesheet, import the default stylesheet at the top of your own file.

    You need to copy the Default Layout Stylesheet to your frontend. You can download the default layout stylesheet from the link within the DataType, we recommend putting the file in the css folder, example: wwwroot/css/umbraco-blockgridlayout.css.

    In this case, you would have to write the layout from scratch.

    You are free to pick any style, meaning there is no requirement to use CSS Grid. It is, however, recommended to use CSS Grid to ensure complete compatibility with the Umbraco backoffice.

    When extending or writing your own layout, you need to know the structure and what data is available.

    For example: You can use the below HTML structure:

    Building Custom Views for Block representations in Backoffice is based on the same API for all Block Editors.

    In this example, we will be creating content programmatically for a "spot" Blocks in a Block Grid.

    1. Create an element type to represent block content called Spot Element with the following properties:

    • A property called title with the editor of Textstring

    • A property called text with the editor of Textstring

    1. Create an element type to represent block content called Spot Settings with the following properties:

    • A property called featured with the editor of True/false.

    1. Add a property called blockGrid in a Document Type.

    2. Select Block Grid as the property editor.

    3. Click Add in the Blocks Settings and select Spot Element.

    4. Select Spot Settings

    The raw input data for the spots looks like this:

    The resulting JSON object stored for the Block Grid will look like this:

    For each item in the raw data, we need to create:

    • One contentData entry with the title and text.

    • One settingsData entry with the featured value (the checkbox expects "0" or "1" as data value).

    All contentData and layoutData entries need their own unique Udi as well as the ID (key) of their corresponding Element Types. In this sample, we only have one Element Type for content (spotElement) and one for settings (spotSettings). In a real life scenario, there could be any number of Element Type combinations.

    1. Create a class called Model.cs containing the following to transform the raw data into Block Grid-compatible JSON:

    1. By injecting and into an API controller, we can transform the raw data into Block Grid JSON. It can then be saved to the target content item. Create a class called BlockGridTestController.cs containing the following:

    For the above code IContent? content = _contentService.GetById(Guid.Parse("efba7b97-91b6-4ddf-b2cc-eef89ff48c3b")); change the id with your content node that is using the Block Grid.

    1. To test this implementation, run the project and send a POST request to /umbraco/api/blockgridtest/create after your domain name. If the result shows as Saved, then check your content node, and you will see the 2 spotElement contents.

    This can also be tested via Postman as well if preferred.

    Editor width - Overwrites the width of the property editor. This field takes any valid CSS value for "max-width". For example: 100% or 800px.
  • Create Button Label - Overwrites the label on the Create button.

  • Create modal size - Controls the size of the overlay dialog that appears when an editor clicks to create or edit a block.

  • Grid Columns - Define the number of columns in your Block Grid. The default is 12 columns.

  • Layout Stylesheet - Replaces the built-in Layout Stylesheet. Additionally, you can retrieve the default layout stylesheet to use as a base for your own inspiration or for writing your own stylesheet.

  • Allowed block types - When this is empty, all Blocks with Permissions for creation in Areas, will be available. This can be overwritten by specifying the allowed Blocks. Define the types of Blocks or Groups of Blocks that are allowed. Additionally, you can also set how many Blocks of each type/group should be present.

    settings - The block's settings data (if configured)

  • rowSpan and columnSpan - Layout dimensions for the block

  • areaGridColumns - Number of columns for nested areas

  • areas - Array of nested areas within the block, each containing their own items

  • in the
    Settings model
    field.
    One layout entry with the desired column and row spans.

    A set of built-in Partial Views are responsible for rendering the Blocks and Areas in a Block Grid. If you want to tweak or change the way the Block Grid is rendered, you can use the built-in Partial Views as a template:

    1. Clone the views from GitHub. They can be found in /src/Umbraco.Web.UI/Views/Partials/blockgrid/.

    2. Copy the cloned views to the local folder Views/Partials/blockgrid/ .

    3. Make changes to your copied views. The entry point for GetBlockGridHtmlAsync() is the view default.cshtml .

    Block List

    Schema Alias: Umbraco.BlockList

    UI Alias: Umb.PropertyEditorUi.BlockList

    Returns: IEnumerable<BlockListItem>

    Block List is a list editing property editor, using Element Types to define the list item schema.

    The single-mode Block List migration now runs by default when upgrading to v18. If you have custom property editors that nest Block List values, you must implement and register ITypedSingleBlockListProcessor before upgrading. See the article for details.

    Configure Block List

    The Block List property editor is configured in the same way as any standard property editor, via the Data Types admin interface.

    To set up your Block List Editor property, create a new Data Type and select Block List from the list of available property editors.

    Then you will see the configuration options for a Block List as shown below.

    The Data Type editor allows you to configure the following properties:

    • Available Blocks - Here you will define the Block Types to be available for use in the property. For more information, see .

    • Amount - Sets the minimum and/or maximum number of blocks that should be allowed in the list.

    • Live editing mode - Enabling this will make editing of a block happening directly to the document model, making changes appear as you type.

    Block Types are Element Types which need to be created before you can start configuring them as Block Types. This can be done directly from the property editor setup process. You can also set them up beforehand and add them to the block list after.

    Once you have added an element type as a Block Type on your Data Type you will have the option to configure it further.

    Each Block has a set of properties that are optional to configure. They are described below.

    You can configure the properties in the group to customize the user experience for your content editors. This helps them to quickly identify and select the right blocks for their content.

    • Label - Define a label for the appearance of the Block in the editor. The label uses to display values of properties. The label is also used for search in the Add Block dialog during content editing. If no label is defined, the block will not be searchable. The search does not fall back to the block’s name.

    • Overlay editor size - Set the size for the Content editor overlay for editing this block.

    It is possible to use two separate Element Types for your Block Types. Its required to have one for Content and optional to add one for Settings.

    • Content model - This presents the Element Type used as model for the content section of this Block. This cannot be changed, but you can open the Element Type to perform edits or view the properties available. Useful when writing your Label.

    • Settings model - Add a Settings section to your Block based on a given Element Type. When picked you can open the Element Type or choose to remove the settings section again.

    These properties refer to how the Block is presented in the Block catalogue, when editors choose which Blocks to use for their content.

    • Background color - Define a background color to be displayed beneath the icon or thumbnail. For example, #424242.

    • Icon color - Change the color of the Element Type icon. For example, #242424.

    • Thumbnail - Pick an image or SVG file to replace the icon of this Block in the catalogue.

    The thumbnails for the catalogue are displayed at a maximum height of 150px and will scale proportionally to maintain their original aspect ratio. Any standard image format (PNG, JPG, SVG) will work effectively.

    These properties are relevant when you work with custom views.

    • Hide content editor - If you made a custom view for editing a block's content, you might want to hide the content-editor from the block editor overlay. This applies when using default editing mode (not inline).

    When viewing a Block List editor in the Content section for the first time, you will be presented with the option to add content.

    Clicking the Add content button brings up the Block Catalogue. If you only have a single block configured, this button will display "Add {block type name}".

    The Block Catalogue looks different depending on the amount of available Blocks and their catalogue appearance.

    Click the Block Type you wish to create and a new Block will appear in the list.

    Depending on whether your Block List Editor is setup to use default or inline editing mode you will see one of the following things happening:

    In default mode you will enter the editing overlay of that Block:

    In inline editing mode, the new Blocks will expand to show its inline editor:

    More Blocks can be added to the list by clicking the "Create new" button. You can also use the inline Add button that appears on hover between or above existing Blocks.

    To reorder the Blocks, click and drag a Block up or down to place in the desired order.

    To delete a Block click the trash-bin icon appearing on hover.

    Rendering the stored value of your Block List property can be done in two ways.

    You can choose to use the built-in rendering mechanism for rendering blocks via a Partial View for each block.

    The default rendering method is named GetBlockListHtml() and comes with a few options to go with it. The typical use could be:

    "MyBlocks" above is the alias for the Block List editor.

    If using ModelsBuilder the example can be simplified:

    Example:

    To make this work you will need to create a Partial View for each block. The partial view should be named by the alias of the Element Type that is being used as Content Model.

    These partial views must be placed in this folder: Views/Partials/BlockList/Components/. Example: Views/Partials/BlockList/Components/MyElementTypeAliasOfContent.cshtml.

    A Partial View will receive the model of Umbraco.Core.Models.Blocks.BlockListItem. This gives you the option to access properties of the Content and Settings section of your Block.

    In this example of a Partial view for a Block Type, the MyElementTypeAliasOfContent and MyElementTypeAliasOfSettings should correspond with the selected Element Type Alias for the given model.

    Example:

    ContentModels.MyElementTypeAliasOfContent must be replaced with the PascalCase version of your Element Type alias, as generated by ModelsBuilder. For example, an Element Type with alias exampleBlock becomes ContentModels.ExampleBlock.

    With ModelsBuilder:

    A built-in value converter is available to use the data as you like. Call the Value<T> method with a generic type of IEnumerable<BlockListItem> and the stored value will be returned as a list of BlockListItem entities.

    Example:

    Replace MyFolderOfBlocks/ with the path to your partial views folder. If using the default location, this should be ~/Views/Partials/BlockList/Components/.

    Each item is a BlockListItem entity that contains two main properties Content and Settings. Each of these is a IPublishedElement which means you can use all the value converters you are used to using.

    Example:

    Sometimes, you might want to use the Block List Editor to hold some data and not necessarily render a view. This applies when the data should be presented in different areas on a page. An example could be a product page with variants stored in a Block List Editor.

    In this case, you can extract the variant's data using the following, which returns IEnumerable<IPublishedElement>.

    Example:

    .Select(x => x.Content) strips away the BlockListItem wrapper and returns the IPublishedElement content data, discarding the settings.

    If using ModelsBuilder the example can be simplified:

    Example:

    Replace the following:

    • Model.Variants with the ModelsBuilder-generated property name for your Block List property, for example Model.BlockListPropertyExample.

    • <ProductVariant> with the ModelsBuilder-generated class name for your element type, for example QuoteBlock.

    If your Block List Editor only uses a single block, you can cast the collection to a specific type. Supply a type T using .OfType<T>(), otherwise the return value will be IEnumerable<IPublishedElement>.

    Building Custom Views for Block representations in Backoffice is the same for all Block Editors.

    Sometimes you need to create or update Block List content via code, for example, during content migrations, data imports, or automated workflows. This section explains how to achieve this using IContentService and IContentTypeService.

    Block List data is stored as a JSON string. Understanding this structure is essential before writing any import code.

    • layout: Defines the order blocks appear in and links each block to its content through a contentKey (a GUID). If the block has a Settings model, the layout entry also holds a settingsKey.

    • contentData: Holds the property values for each block. Every entry must include a key matching a contentKey in the layout, a contentTypeKey

    The following example shows how to build a Block List and save it to an existing content node. It assumes you have:

    • A Document Type with a Block List property aliased timelineItems.

    • An Element Type aliased timelineItem with two properties: eventName (Textstring Data Type) and period (Textstring Data Type).

    Create a TimelineImportController.cs file in MyProject/Controllers.

    1. Rebuild and run your project.

    2. Make a POST request to:

    With this body, substituting your actual GUID from the Info tab:

    You can use Postman, Bruno, or the browser's fetch console to make the call. If you get a 401 back, the endpoint needs authentication. In that case, the quickest fix for local testing is to add [AllowAnonymous] to the controller temporarily.

    1. Open your content node in the Backoffice.

    2. Check the timelineItems Block List property. You should see the imported blocks populated with your data.

    1. Create a Partial View for the timelineItem element type to render the imported blocks on the frontend at: Views/Partials/BlockList/Components/timelineItem.cshtml.

    Example partial:

    1. Render the Block List in your page template using:

    1. Browse to your page on the frontend (for example, https://localhost:{port}) and you should see each imported block rendered.

    By default, calling SetValue() with a new JSON structure overwrites all existing blocks. Use this approach instead if you need to preserve existing content.

    To append new blocks to an existing list without losing current content, read and deserialize the existing value first. Then append to those collections before saving. Update the Import method in your controller:

    If your Block Type has a Settings model configured, each block needs a settingsKey referenced in both layout and settingsData. A Settings model is the optional second Element Type you can attach to a block. It is commonly used to let editors control things like background color, padding, or visibility toggles separately from the block's content.

    To use settings, fetch both Element Types and generate a separate key for each block's settings entry. Declare a settingsData list alongside the other collections and pass it when constructing the value: new BlockListValue(layout) { ContentData = contentData, SettingsData = settingsData, Expose = expose }.

    If your site uses multiple languages and your Document Type is configured to vary by culture, pass the target culture string to SetValue() and GetValue().

    Ensure Allow vary by culture is enabled on your Document Type in the Settings tab. The Block List property's Variation ("Shared across cultures") should be disabled. The Variation option on the Block List property editor only appears once the Document Type is set to vary by culture.

    Inline editing mode
    - Enabling this will change editing experience to inline, meaning that editing the data of blocks happens at sight as accordions.
  • Property editor width - Overwrite the width of the property editor. This field takes any valid css value for "max-width".

  • Create modal size- Controls the size of the Block Catalogue dialog shown when an editor clicks "Create new" to choose a block type. It does not affect the block's content-editing overlay (for either creating or editing a block's content). The overlay's size is set per Block Type via Overlay editor size.

  • Single block mode - When enabled, the Block List is restricted to a single block and the property returns a BlockListItem<> instead of BlockListModel

  • matching the GUID of the Element Type, and a
    values
    array of
    { "alias", "value" }
    pairs.
  • settingsData: Holds settings values if your Block Type has a Settings model configured. It follows the same shape as contentData.

  • expose: Lists which blocks are visible, per culture and segment. A block is only rendered if it has a matching expose entry. For invariant content, use null for both culture and segment.

    Understanding the Block List JSON Format

    Before Umbraco 14, Block List data used a different format. Blocks were referenced by UDI (umb://element/...), property values were stored as flat keys, and there was no expose array. That legacy format is no longer supported in Umbraco 18, so always write new content in the format shown below.

    You do not need to build this JSON by hand. Umbraco exposes strongly-typed models — BlockListValue, BlockListLayoutItem, BlockItemData, BlockPropertyValue, and BlockItemVariation — that serialize to exactly this structure through IJsonSerializer. The examples below use these models.

    Appending to an Existing Block List

    Using Settings Models

    Settings do not need their own expose entry — expose only references a block's contentKey. If your block type has no Settings model, leave SettingsData empty (its default).

    Handling Multilingual (Variant) Content

    Always pass the same culture string to both GetValue() and SetValue(). Omitting the culture from GetValue() reads the invariant slot, which is empty on a culture-variant property, causing existing blocks to be overwritten instead of appended.

    Breaking Changes Overview

    Breaking changes introduced in each major version of Umbraco CMS, with notes on what to update when upgrading.

    Use the information below to learn about any potential breaking changes and common pitfalls when upgrading your Umbraco CMS project.

    If any specific steps are involved with upgrading to a specific version they will be listed below.

    Use the general upgrade guide to complete the upgrade of your project.

    Preparation for Upgrade

    Before running the upgrade, consider the following:

    Upgrade to Umbraco 17 first

    Umbraco 18 can only upgrade from Umbraco 16.4 or later, because it no longer includes the migrations from Umbraco 13 to 17. Upgrade your project to Umbraco 17, the latest Long-term Support (LTS) version, before you upgrade to Umbraco 18.

    Empty the media recycle bin

    In Umbraco 18, the EnableMediaRecycleBinProtection setting defaults to true. With this enabled, media files moved to the recycle bin are renamed with a .deleted suffix (and renamed back on restore). Emptying the media recycle bin before upgrading avoids any uncertainty around the state of files already in the bin from prior versions.

    For details, see the entry on EnableMediaRecycleBinProtection further down.

    The single-mode block list migration was added in Umbraco 17 but disabled by default. It now runs automatically during the upgrade to Umbraco 18.

    If your site has custom property editors that nest block list values, you must implement and register an ITypedSingleBlockListProcessor before upgrading. Without this, nested data in those property values will not be migrated and will remain in the old format.

    For details, see the article.

    You can find a list of all the released Umbraco versions on website. When you visit Our Umbraco website, click on the version number to view the changes made in that specific version.

    Breaking changes

    Umbraco 18

    Swashbuckle replaced with Microsoft.AspNetCore.OpenApi

    Umbraco no longer uses Swashbuckle for OpenAPI documentation. It has been replaced with Microsoft.AspNetCore.OpenApi. If you have custom APIs with OpenAPI documentation, you will need to update your code.

    You can still use Swashbuckle for your own OpenAPI documents if you prefer, but Umbraco no longer ships or configures it. You are responsible for installing the Swashbuckle.AspNetCore NuGet package and wiring it up yourself.

    The main changes you will need to migrate:

    • Registering OpenAPI documents — replace IConfigureOptions<SwaggerGenOptions> with AddOpenApi() (and AddOpenApiDocumentToUi() to show it in the Swagger UI dropdown). See . For backoffice APIs, the new AddBackOfficeOpenApiDocument(name, configure) builder wires up authentication and Umbraco's conventions in one call — see .

    • Backoffice security requirements — replace BackOfficeSecurityRequirementsOperationFilterBase with the AddBackofficeSecurityRequirements() extension. See .

    • Schema ID handlers — ISchemaIdHandler / SchemaIdHandler / ISchemaIdSelector / SchemaIdSelector have been removed. Use CreateSchemaReferenceId on OpenApiOptions. See .

    • Operation ID handlers — IOperationIdHandler / OperationIdHandler / IOperationIdSelector / OperationIdSelector have been removed. Use IOpenApiOperationTransformer. See .

    • Sub-types handlers — ISubTypesHandler, ISubTypesSelector, SubTypesHandler, and SubTypesSelector have been removed. Configure JSON polymorphism through JsonSerializerOptions instead.

    • Document inclusion selector — IDocumentInclusionSelector and DocumentInclusionSelector have been removed. Each document now controls its own membership through ShouldInclude.

    • Enum schema filter — EnumSchemaFilter has been removed. Enum serialization is now driven by the document's JsonOptions.

    • Delivery API member authentication — ConfigureUmbracoMemberAuthenticationDeliveryApiSwaggerGenOptions has been removed. Use the AddDeliveryApiOpenApiMemberAuthentication() extension. See .

    • Route and availability configuration — OpenApiRouteTemplatePipelineFilter overrides are no longer supported. Use PostConfigure<UmbracoOpenApiOptions> instead. See .

    • Controlling which endpoints appear in your document — [MapToApi] no longer auto-filters custom documents. Set ShouldInclude on each document. See .

    • OpenAPI spec version — generated documents now use OpenAPI 3.1 instead of 3.0. Regenerated client SDKs may differ — verify your generator supports OpenAPI 3.1.

    • Source generator compilation (class libraries) — class library projects that register OpenAPI documents must add <InterceptorsNamespaces>$(InterceptorsNamespaces);Microsoft.AspNetCore.OpenApi.Generated</InterceptorsNamespaces> to their .csproj. Without it, the build fails with "error CS9137: The 'interceptors' feature is not enabled." See .

    OpenAPI URL changes

    The OpenAPI endpoints have been renamed from swagger to openapi to follow Microsoft's naming conventions:

    Old URL
    New URL

    UmbracoApiController and front-end API auto-routing removed

    The UmbracoApiController base class — obsoleted in Umbraco 15 — has now been removed, along with the convention-based front-end API auto-routing pipeline that supported it. Custom APIs must be written as standard ASP.NET Core controllers using the [ApiController] and [Route] attributes.

    Before:

    After:

    IPublishedContent.Parent and IPublishedContent.Children removed

    The Parent and Children navigation members on IPublishedContent — obsolete in earlier versions — have now been removed.

    In Razor views and other code with access to the ambient Umbraco services, switch to the equivalent extension methods Parent() and Children(), defined in the Umbraco.Extensions namespace.

    Before:

    After:

    The extension methods are designed for view-side use and rely on ambient Umbraco services that may not be set up outside a web request. In code that runs outside a request — for example, a background service — inject IDocumentNavigationQueryService (or IMediaNavigationQueryService for media) to obtain parent and child keys. Resolve those keys through IPublishedContentCache or IPublishedContentQuery.

    GetAtRoot() removed

    The GetAtRoot() method — obsolete in earlier versions — has now been removed from UmbracoHelper, IPublishedContentCache, and IUmbracoContext.Content. The replacement depends on the use case:

    • To enumerate all root nodes inside a web request, use ContentAtRoot() on UmbracoHelper or IPublishedContentQuery:

    • To enumerate root nodes outside a web request, inject IDocumentNavigationQueryService (or IMediaNavigationQueryService for media) and use its TryGetRootKeys(out IEnumerable<Guid> rootKeys) method to obtain the root keys, then resolve them via IPublishedContentCache.GetById(key)

    Content finder and URL provider renames

    The earlier ContentFinderByUrl and DefaultUrlProvider classes — obsolete since their New-suffixed replacements were introduced — have now been removed, and the replacements have been renamed to drop the suffix:

    • ContentFinderByUrlNew → ContentFinderByUrl

    • NewDefaultUrlProvider → DefaultUrlProvider

    ILocalizationService removed

    ILocalizationService — obsolete since Umbraco 12 — has now been removed. Its responsibilities have been split between two services:

    • ILanguageService for language operations.

    • IDictionaryItemService for dictionary item operations.

    The new services expose an asynchronous API throughout, removing the sync-over-async patterns that existed on ILocalizationService.

    Before:

    After:

    For dictionary item operations such as GetDictionaryItemByKey, switch the injected service to IDictionaryItemService and use the corresponding async method.

    IFileService split into per-file-type services

    IFileService — obsolete in earlier versions — has now been removed. Its functionality was previously moved into four dedicated services:

    Service cleanups: obsolete sync method removals

    Synchronous methods on the following services — obsolete in earlier versions in favor of async equivalents — have now been removed. Switch to the …Async overloads:

    • IContentTypeBaseService and IDomainService ()

    • IDataTypeService ()

    • IEmailSender, MediaPermissions

    IHostingEnvironment.ApplicationMainUrl is now nullable

    The ApplicationMainUrl property on IHostingEnvironment is now declared as Uri?. Add a null-check before using it. See .

    UmbracoHelper.GetDictionaryValue nullability change

    The return type of GetDictionaryValue has been changed from string? to string. This matches the actual runtime behavior — an empty string is returned when no dictionary item is found for the key. Callers can remove any defensive null checks against the return value. See .

    MigrationBase removed — migrations must inherit AsyncMigrationBase

    The synchronous MigrationBase class has been removed. It was obsoleted in Umbraco 16, when AsyncMigrationBase was introduced.

    All bundled migrations between Umbraco 13 and 17 have also been deleted. Custom migrations must inherit AsyncMigrationBase and implement MigrateAsync.

    The synchronous PackageMigrationBase has likewise been removed. Package migrations must inherit AsyncPackageMigrationBase.

    Before:

    After:

    Custom migration plans must also be executed via IMigrationPlanExecutor.ExecutePlanAsync().

    Master Template renamed to Layout Template

    To match the terminology used elsewhere in the editor and templating engine, "Master Template" has been renamed to "Layout Template" throughout the codebase:

    • ITemplate adds IsLayoutTemplate and LayoutTemplateAlias properties.

    • Service parameters previously named masterTemplateId are now layoutTemplateId.

    The old MasterTemplate… members are retained as [Obsolete] shims and will be removed in Umbraco 20.

    HideBackOfficeLogo content setting removed

    The HideBackOfficeLogo option has been removed from ContentSettings. Remove any entries for it from appsettings.json.

    EnableMediaRecycleBinProtection now defaults to true

    The EnableMediaRecycleBinProtection content setting — introduced in Umbraco 17 — now defaults to true. With protection enabled, media files moved to the recycle bin are renamed with a .deleted suffix (and renamed back on restore). A middleware component blocks unauthenticated access to recycle bin media URLs.

    To restore the previous (unprotected) behavior, set Umbraco:CMS:Content:EnableMediaRecycleBinProtection to false in your configuration.

    Default markdown converter changed

    MarkdigMarkdownToHtmlConverter is now the default registered implementation of IMarkdownToHtmlConverter, replacing the previous Hey Red Markdown-based default.

    The Hey Red Markdown library is deprecated, and the corresponding implementation will be removed in Umbraco 19. To revert to the previous behavior for now, register HeyRedMarkdownToHtmlConverter explicitly in a composer.

    EF Core type names: EfCore renamed to EFCore

    EF Core code constructs in Umbraco.Cms.Persistence.EFCore have been renamed to use the all-uppercase EF acronym. For example, EfCoreScope is now EFCoreScope, IEfCoreScopeProvider is now IEFCoreScopeProvider, and EfCoreMigrationExecutor is now EFCoreMigrationExecutor. Code that referenced these types directly must be updated to the new casing.

    Block list "single mode" migrated to the single block editor

    Umbraco 17 shipped a migration to convert "single" mode block list Data Types to the new single block property editor, but kept it disabled. It now runs by default in Umbraco 18.

    Standard block list Data Types are migrated automatically and require no action. Sites with custom property editors that nest block list values must implement ITypedSingleBlockListProcessor so their nested data is migrated correctly.

    ConfigureSecurityStampOptions service registration removed

    The ConfigureSecurityStampOptions options-configuration class is no longer registered by the framework. Host applications that copied Program.cs from earlier versions should remove any explicit services.ConfigureOptions<ConfigureSecurityStampOptions>() call.

    Updated dependencies

    As is usual for a major upgrade, Umbraco's dependencies have been updated to their latest compatible versions.

    Markdig was updated to a major version from 0.45.0 to 1.1.x. If you are using this library directly — for example, via MarkdigMarkdownToHtmlConverter — minor API differences may be encountered.

    Microsoft.CodeAnalysis.CSharp was updated by a major version from 4.14.0 to 5.0.0. Projects that take a direct dependency on Roslyn for code analysis may need updates.

    The Serilog hosting packages were updated by a major version from 9.0.0 to 10.0.0. This includes Serilog.AspNetCore, Serilog.Extensions.Hosting, and Serilog.Settings.Configuration. Sites with custom Serilog configuration should review the .

    Asp.Versioning.Mvc was updated by a major version from 8.1.1 to 10.0.0. Custom code using these APIs should review the new major version for breaking changes.

    Umbraco 17

    System dates are updated to UTC

    In earlier versions of Umbraco, system dates have been primarily persisted as server time without time zone information, with some stored as UTC. With Umbraco 17, system dates are now always stored in UTC.

    To ensure that existing stored system dates align, a migration will run when upgrading to Umbraco 17.

    The migration consists of:

    • Determining the current time zone for the server.

    • If a time zone is detected and it is not already UTC, database queries will update all system dates previously stored as server time to UTC.

    There is configuration available to customize this migration.

    Adding the following configuration setting will disable the migration from running.

    You can also explicitly define the time zone for your server. If this is provided as the standard English name of the time zone, it will be used over the detected one.

    Progress of the migration is written to the Umbraco log file.

    InMemoryAuto models builder and Razor runtime compilation have moved into their own package

    The InMemoryAuto models builder and the Umbraco feature that uses Razor runtime compilation (Microsoft.AspNetCore.Mvc.Razor.RuntimeCompilation) have been moved to a separate package: Umbraco.Cms.DevelopmentMode.Backoffice.

    Why was this change made?

    and prevents Hot Reload from working. Since InMemoryAuto depends on Razor runtime compilation, keeping it in the core would prevent Hot Reload from working.

    By moving InMemoryAuto to its own package, Umbraco can enable Hot Reload by default for a better development experience.

    When you need to reference Umbraco.Cms.DevelopmentMode.Backoffice?

    Add the package if any of the following apply:

    1. You use the InMemoryAuto models builder:

      • By explicitly selecting InMemoryAuto.

      • By starting a new project with the default --models-mode (which is InMemoryAuto

    When you do not need the package?

    You don’t need to reference it if you use Models Builder in a source-code mode, such as:

    • AppData

    • SourceCodeAuto

    • SourceCodeManual

    Additional notes

    If you use the ModelsMode enum or its extension methods, use the string constants in Constants.ModelsBuilder.ModelsModes instead.

    For more details on this update, see .

    Date Picker Property Editor Kind

    The existing date picker that returns a DateTime object has been updated to provide one with a Kind of Unspecified. Previously, it was UTc, but this was incorrect because Umbraco cannot determine the intended use of a particular date picker. This update makes that explicit.

    For more details on this update see the following PR: .

    Color Picker Property Editor

    The color picker property editor used for the built-in approved color Data Type will now always make available a PickedColor object. Previously, this was only output when labels were configured on the Data Type. Without labels the previous behavior was to expose a string.

    For more details on this update see the following PR: .

    Segmented Content Fallback

    The Template and Delivery API output for segmented properties will perform an explicit fallback to the default segment, if they do not have a value.

    In earlier versions, if you created a segmented version of a document, you had to complete every property. This made segments an editorial burden unless the behavior was customized. With the new behavior, segmented content now only needs to have the properties that require a segmented value completed.

    For more details on this update see the following PR: .

    Removal of Extension Methods

    Extension and public helper methods, unused in Umbraco and obsolete in previous versions, have been removed.

    These are:

    • GetAssemblyFile

    • ToSingleItemCollection

    • GenerateDataTable, CreateTableData, AddRowData,

    For more details on this update see the following PR: .

    Tiptap external extensions package

    The import namespace @umbraco-cms/backoffice/external/tiptap has been removed, replaced with @umbraco-cms/backoffice/tiptap.

    This means backoffice extension code must be updated from:

    To:

    For more details on this update see the following PR: .

    Client-side user related entities

    The following components have been moved from user to current-user and exported.

    • UmbCurrentUserAllowMfaActionCondition

    • UmbCurrentUserConfigRepository

    • UmbCurrentUserConfigStore

    They should now be imported from @umbraco-cms/backoffice/current-user.

    For more details on this update see the following PR: .

    URL provider updates

    URL providers are now responsible for generating content preview URLs. To achieve this, the IUrlProvider interface has been extended with the GetPreviewUrlAsync() method.

    The IUrlProvider interface must also provide a unique system-wide Alias.

    Lastly, the UrlInfo class has been revamped to support this setup.

    For more details on this update see the following PR: .

    See also this announcement: .

    HTTPS is enabled by default

    The default value of the UseHttps configuration in has been changed from false to true.

    If you need to run Umbraco without HTTPS, make sure to update appsettings.json accordingly.

    Authentication for the backoffice client

    Following the draft , the backoffice client authentication has been changed to tighten security.

    This change affects only the backoffice client authentication against the Management API. API user authentication against the Management API remains unaffected, as does the Delivery API.

    This change might affect custom backoffice extensions that interact with the Management API. All fetch requests to the Management API must include credentials by declaring credentials: 'include'.

    By default, backoffice extensions built using the HQ package starter template are not affected.

    For more details on this update, see the following PRs: and .

    Updated dependencies

    As is usual for a major upgrade, Umbraco’s dependencies have been updated to their latest compatible versions.

    NPoco was updated by a major version from 5.7.1 to 6.1.0. There were some changes to Umbraco code necessary after this update, so customer projects or packages that use NPoco directly may also require some changes.

    Swashbuckle was updated to a new major version 10.0.1. If you are using this library to provide a Swagger document in your package or project, changes around namespaces, nullability, and types will be encountered.

    The other specific dependency updates made for Umbraco 17 for server and client-side libraries can be found in these PRs:

    Sections

    In UmbSectionContext, the setManifest() method has been replaced with a manifest. This is done to align with most other extension types. The ManifestSection interface has been modified to extend ManifestElementAndApi instead of ManifestElement. The UmbSectionElement that a section extends from now extends UmbControllerHostElement instead of HTMLElement.

    Umbraco 16

    TinyMCE is removed

    In Umbraco 15, two property editors were available for a rich text editor: TinyMCE and TipTap.

    With Umbraco 16, only TipTap is available as an option out of the box. TinyMCE's change of license precludes us from shipping it with the MIT-licensed Umbraco CMS.

    When upgrading to Umbraco 16, any data types using TinyMCE will be migrated to use TipTap.

    To continue to use TinyMCE, a third-party package must be installed prior to the upgrade. This will disable the migration and allow you to continue with TinyMCE.

    Package migrations are asynchronous

    Umbraco 16 adds support for asynchronous migrations and part of this work involved creating a new base class for package migrations. This leads to a source-compatible but binary-incompatible breaking change. In practice, this means that package code using migrations and calling base class helper methods such as TableExists can be recompiled without change. But if built against 15 and run on 16, a "method missing" exception will be thrown. For more details on the feature and the changes implemented, see the .

    Examine is now registered via a composer

    is being worked on in an external package. To support this, a method has been implemented to disable the default Examine-based search in Umbraco. This has required moving the Examine component registration to a composer.

    There is no effect on the default search experience in Umbraco, but it may affect search customizations. As Examine is now registered in a composer, any custom code registered the same way is not guaranteed to run after the core setup. You should ensure to use a [ComposeAfter(typeof(Umbraco.Cms.Infrastructure.Examine.AddExamineComposer))] attribute to make sure custom code runs after Umbraco's default setup of Examine.

    Read more in the article on and see for reference.

    Updated dependencies

    As is usual for a major upgrade, the dependencies Umbraco takes have been updated to their latest, compatible versions. This had little impact on the code of Umbraco itself, so we don't expect this to affect upgraded customer projects.

    The specific dependency updates made for Umbraco 16 can be found in these PRs: for and libraries.

    Other breaking changes

    Other than the above, breaking changes are minimal in Umbraco 16. On the server side, changes are limited to removing already obsolete constructors and methods.

    Client-side there are a few things to look out for if you've built extensions to the backoffice:

    • When consuming contexts, an undefined response will be resolved when the context can't be provided or the host is disconnected. See for more information.

    • Similarly, consuming a context as a promise can result in a promise rejection and getting a context can result in an undefined response. See for more information.

    • When making calls to retrieve data from the server, if you used either of Umbraco's helper methods tryExecute or tryExecuteAndNotify

    The full details of breaking changes can be found from .

    Umbraco 15

    Snapshots are removed

    Snapshots have been removed, meaning any code using IPublishedSnapshot, and by extension IPublishedSnapshotAccessor, must be updated. Inject IPublishedContentCache or IPublishedMediaCache and use those directly instead.

    Modelsbuilder models needs to be rebuilt

    Models generated by ModelsBuilder used the IPublishedSnapshot interface, which has been removed. This means that the models need to be rebuilt. The approach to this will differ depending on the mode chosen:

    InMemoryAuto

    Remove the umbraco\Data\TEMP\InMemoryAuto folder to trigger a rebuild of the models.

    SourceCodeAuto and SourceCodeManual

    Remove the old models located in the \umbraco\models folder by default. This will cause your views to no longer be able to build due to missing types. To get around this you can disable the precompiled view temporarily by adding the following to your .csproj file:

    This will allow your site to start up, but you will still see an error page when loading a page.

    1. Disregard the error.

    2. Enter the backoffice.

    3. Rebuild the models from the ModelsBuilder dashboard.

    You can now re-enable precompiled views and rebuild your site.

    If you have custom C# code that references the models this will also not build. You can either comment out your custom code temporarily until the models have been rebuilt or fix the models manually. To fix the models manually you need to find and replace IPublishedSnapshotAccessor with IPublishedContentTypeCache.

    Handling Precompressed Files

    When upgrading from Umbraco 14 to 15, you might notice that JavaScript and CSS files are automatically precompressed, adding additional .br and .gz files. This behavior is introduced in ASP.NET Core version 9, where static files are fingerprinted and precompressed by default at build and publish time.

    To disable this feature, set <CompressionEnabled>false</CompressionEnabled> in your project file. If you are using Umbraco's templates: dotnet new umbraco, this setting is already included.

    In the project containing the /umbraco folder, set <CompressionEnabled>false</CompressionEnabled> in the .csproj file. This ensures the CMS can manage its own system files correctly. If you have separate Class Library projects for your custom frontend assets (CSS, JS), you may set this to true for performance benefits.

    For more details, see the .

    Umbraco 14

    Read more about the release of Umbraco 14 in the Blog Post.

    Below you can find the list of breaking changes introduced in Umbraco 14 CMS.

    • AngularJS removed: A new backoffice built with Web Components, Lit, and fueled by the Umbraco UI Library

    This is by far the most impactful update of Umbraco in years. We’ve fundamentally changed the way you extend Umbraco. If you are experienced in developing Web Components you can now use your preferred framework for this. If you are unsure how to proceed, you can implement it with TypeScript and the Lit library like we’ve done. In this case, start with this article on how to customize the Backoffice.

    The new Backoffice (Bellissima) is entirely built on the Umbraco UI Library. This means that you might experience some of your components not being rendered on the page because the name has been changed. You should be able to find equivalents to what you were used to. For example, the umb-button is now called uui-button, and umb-box is now uui-box. When extending the Backoffice, we encourage you to use our to ensure the same look and feel in your extensions. The UI Library is Open Source and , so feel free to contribute with new components or raise issues or discussions.

    • Icons are based on Lucide.

    Umbraco 13 and earlier used sets of icons ranging from custom SVGs to Font Awesome. This has all been converged into the with icon names mapped from Umbraco 13.

    • Custom icons

    To add custom icons to the Backoffice, you must add an extension type called “icons”, which can provide icons given a Name and a File. The file can reside anywhere on disk or in RCLs the only requirements being that it must be routable and it must be an SVG.

    • User provided translations

    Translations used in the UI (which are most of them) have been migrated from XML to JavaScript modules. This means that if you wish to override any of the built-in translation keys for the UI, you have to add an extension type called “localization”. It is still possible to add XML translations, but they can no longer be used in the Backoffice UI. However, you may still find usage for them in server-to-server scenarios. Umbraco also keeps its e-mail templates as XML translations. Package and extension developers working with localization will find many benefits from this change seeing that you can add logic to JavaScript modules making your localization files more dynamic and even making them able to react to input parameters.

    You can read more about .

    • BackOffice controllers have been replaced with the Management API

    Following the implementation of the new Backoffice (Bellissima), Umbraco has now internally upgraded Headless to a first-class citizen. This means that all controllers previously available under the /umbraco/api route have been removed and replaced with controllers in the Management API. You can read more about the Management API on the article. You can also check out the Swagger UI in your local Umbraco instance available under /umbraco/swagger.

    • A new way of writing authorized controllers

    If you have implemented API controllers in Umbraco before, we recommend you update or rewrite these. Follow the article, as you’ll then ensure the same cool documentation of your APIs. Notice, that we’ve made a much better separation of concern between controllers and services so that there is no more business logic in controllers.

    Although this sounds like it's not a big change, it’s one of the most breaking changes on the backend. Whereas Newtonsoft.Json was flexible and error-tolerant by default, System.Text.Json is strict but more secure by default. You can therefore run into things that will not be serialized. You can .

    • Nested Content and Grid Layout have been removed

    These two property editors have been deprecated in Umbraco for some time as you can read in our breaking change announcements for and . The recommended action is to use blocks instead - Block Grid for the grid layout and either Block Grid or Block List for Nested Content.

    We have for some time , and now it’s fully removed. You should use the default Media Picker instead.

    • Macros and Partial View Macros have been removed. Use partial views and/or blocks in the Rich Text Editor (RTE)

    Depending on the usage of macros, you’ll be able to use either partial views or blocks in the Rich Text Editor. They are not the same kind of functionality, but they cover all the identified use cases in a more consistent and supportable way.

    For more information on migrating from macros to using blocks in the Rich Text Editor, see the article.

    • XPath has been removed

    An alternative is using the Dynamic Roots in the Multinode Treepicker and for ContentXPath the alternative is .

    The package.manifest file is no longer supported and has been replaced with the umbraco-package.json file. The format is similar and after building your Umbraco solution, you have access to a JSON schema file which you can reference and thereby have type-safety in the file. You can read more about the new format on the article.

    • Smidge is no longer a default dependency

    along with the RuntimeMinification setting and related classes. Smidge used to bundle up Backoffice and package assets before, however, with the Bellissima, we have migrated entirely to ESModules. This means we can no longer predict how modules work in automated bundles.

    It's recommended that you bundle up your Backoffice static assets for instance by a tool called Vite. You can read more about this on the article. You can still use libraries like Smidge for frontend static assets by manually installing the package from NuGet.

    You can read the on how to set up a similar setting to RuntimeMinification. For sites being upgraded from V13 or below, remove from the _ViewImports.cshtml file.

    • Base classes for Backoffice controllers have been removed

    The UmbracoAuthorizedApiController and UmbracoAuthorizedJsonController classes have been removed. We recommend basing your Backoffice APIs on the ManagementApiControllerBase class from the Umbraco.Cms.Api.Management project.

    Read the for a comprehensive guide to writing APIs for the Management API.

    • Removal of certain AppSettings

    Some AppSettings have been removed or found a new place. In general, any UI-related app settings will now have to be configured as .

    • RichTextEditor

    The global configuration of TinyMCE has been removed in order to support more rich text editors in the future. Instead, a new extension type called “tinyMcePlugin” has been added. This extension type gives you access to each instance of TinyMCE allowing you to configure it exactly as you see fit. You can even make it dependent on more factors such as Document Type, user group, environment, and much more. You have access to the full array of contexts in the Backoffice.

    • ShowDeprecatedPropertyEditors

    There are no deprecated property editors in Bellissima and this configuration will no longer have an effect.

    • HideBackOfficeLogo

    This configuration will no longer have an effect. Instead, you can add a CSS file where you can modify the default CSS variables in the Backoffice. The Backoffice loads a CSS file which can be overwritten by placing a similar file in your project at /umbraco/backoffice/css/user-defined.css with the following content:

    • IconsPath

    This configuration will no longer have an effect. Instead, you should add icons through the “icons” extension type.

    • AllowedMediaHosts

    This configuration will no longer have an effect.

    • Notifications

    Notifications have changed their behavior to an extent. You can still implement notifications such as ContentSavingNotification to react to changes for related systems or add messages to be shown in the Backoffice. You can no longer modify the models being transferred through the API.

    If you wish to modify the Backoffice UI, register the extensions through the manifest system that hook on to the desired areas of the Backoffice UI. If you used to modify the models because you needed more data on the models, it's recommended that you build your own API controller to achieve this. You can read more about and even learn how to register your controllers in Swagger UI.

    • Property editors have been split in two

    The new Backoffice and the Management API ushers in a shift in responsibility. Traditionally, a lot of UI responsibility has been misplaced on the server.

    For example, it is hardly a server concern how many rows a text area should span by default.

    To this end, property editors have been split into two, individually reusable parts; the server implementation and the client implementation.

    This change will likely impact custom Property Editors. See the article for details.

    • Property value converters for package.manifest based property editors

    The package.manifest file format is no longer known on the server side. It has been changed to be a purely client-side responsibility (and it has adopted a new format and a new name). If you have implemented a property value converter for a property editor defined in a package.manifest file, you will likely need to make a small change to the property value converter.

    The property value converter must implement IsConverter() to determine if it can handle a given property. In this implementation, it is common to use the EditorAlias of the passed in IPublishedPropertyType. However, in Umbraco 14 you should use the EditorUiAlias instead.

    More details can be found in .

    • UmbracoApiController breakage

    Due to the shift from Newtonsoft.Json to the System.Text.Json, the UmbracoApiController will yield camel-cased output in Umbraco 14, where it was pascal-cased in the previous versions.

    Make sure to perform thorough testing of all usages of UmbracoApiController. As the class has now been marked as obsolete, we recommend these controllers to be based on the Controller class from ASP.NET Core moving forward.

    • Two-Factor Authentication requires a client registration

    The C# models for Two-Factor Authentication previously supported setting a custom AngularJS view to setup the QR code. This has been moved to the Backoffice client and requires a registration through the new extension type :

    This will use Umbraco’s default configuration of the two-factor provider. The user scans a QR code using an app such as Google Authenticator or Authy by Twilio.

    It is additionally possible to register your own configurator similar to Umbraco 13. You can achieve this by providing a custom JavaScript element through the elementJs property.

    More details and code examples can be found in the article.

    • External Login Providers require a client registration

    The C# models for External Login Providers have changed and no longer hold configuration options for the “Sign in with XYZ” button. To show a button in the Backoffice to sign in with an external provider, you need to register this through the extension type called :

    This will use Umbraco’s default button to sign in with the provider. You can also choose to provide your own element to show in the login form. You can achieve this by adding the elementJs property.

    Additionally, on the backend side, there is an additional helper available to do proper error handling. You can utilize this by using the options pattern to configure the provider.

    More details and code examples can be found in the article.

    • Deprecated SQLite provider name removed

    In previous versions of Umbraco the umbracoDbDSN_ProviderName (and umbracoCommerceDbDSN_ProviderName) value could be Microsoft.Data.SQLite or Microsoft.Data.Sqlite with the former being deprecated in Umbraco 12.

    The deprecated version, Microsoft.Data.SQlite, has been removed and will require the value to be updated to Microsoft.Data.Sqlite for installations using an SQLite database.

    • Webhook payload property casing has changed

    Following changes to serialization, property names in the payload now use camelCase instead of PascalCase. For example, the 'CreateDate' property is now 'createDate'.

    In-depth and further breaking changes for Umbraco 14 can be found on the repository and on .

    Umbraco 12

    Umbraco 12 does not include many binary breaking changes, but there are some.

    Most notable is a functional breaking change in Migrations, that from Umbraco 12. Each translation will be executed in its own transactions instead of all migrations in one big transaction. This change has been made to ease the support for Sqlite.

    A type, enum, record, or struct visible outside the assembly is missing in the compared assembly when required to be present.

    • PagedModel has moved namespace from Umbraco.New.Cms.Core.Models to Umbraco.Cms.Core.Models

    • Umbraco.Cms.Infrastructure.Migrations.PostMigrations.ClearCsrfCookies is removed. The functionality can be archived by implementing a notification handler for the new UmbracoPlanExecutedNotification.

    • Umbraco.Cms.Core.Cache.DistributedCacheBinder is now divided into separate files for each notification handler

    • Umbraco.Cms.Infrastructure.Migrations.PostMigrations.DeleteLogViewerQueryFile was a no-op method removed.

    • Umbraco.Cms.Infrastructure.Migrations.PostMigrations.RebuildPublishedSnapshot replaced with a RebuildCache flag on the MigrationBase

    A member that is visible outside of the assembly is missing in the compared assembly when required to be present.

    • Umbraco.Cms.Core.Migrations.IMigrationPlanExecutor.Execute(Umbraco.Cms.Infrastructure.Migrations.MigrationPlan,System.String) replaced with Umbraco.Cms.Core.Migrations.IMigrationPlanExecutor.ExecutePlan(Umbraco.Cms.Infrastructure.* * Migrations.MigrationPlan,System.String) that returns an rich object instead of a string

    • Umbraco.Cms.Infrastructure.Migrations.IMigrationContext.AddPostMigration``1 Removed and replaced with notification

    • Umbraco.Cms.Infrastructure.Migrations.MigrationPlan.AddPostMigration``1

    • Removed and replaced with notification

    An abstract member was added to the right side of the comparison to an unsealed type.

    • PublishedPropertyBase now requires inheritors to implement GetDeliveryApiValue(System.Boolean,System.String,System.String)

    A member was added to an interface without a default implementation.

    • Umbraco.Cms.Core.Events.IEventAggregator.Publish2(System.Collections.Generic.IEnumerable{0})

    • Umbraco.Cms.Core.Events.IEventAggregator.PublishAsync2(System.Collections.Generic.IEnumerable{0},System.Threading.CancellationToken)

    • Umbraco.Cms.Core.Models.PublishedContent.IPublishedProperty.GetDeliveryApiValue(System.Boolean,System.String,System.String)

    Umbraco 11

    Most breaking changes are introduced due to updated dependencies. The breaking changes in .NET 7 and ASP.NET Core 7 are documented by Microsoft.

    Besides the documented changes, we have also seen a few method signatures that are changed to support Nullable-Reference-Types.

    If you are using TinyMCE plugins or custom TinyMCE configuration you need to migrate to the latest version. Learn more about this in the Rich Text Editor documentation.

    The breaking changes in TinyMCE are also documented in the official migration guides for version 4 to 5 and from version 5 to 6.

    The breaking changes in Umbraco 11 are mainly the removal of classes, methods, and so on, marked as obsolete in Umbraco 9.

    A few methods and classes have also been moved and changed namespace. Decoupled dependencies are documented on the .

    The full list of API-breaking changes can be found below.

    Obsolete code removed

    The following have been removed after having been obsoleted since Umbraco 9.

    Umbraco.Extensions

    Umbraco.Cms.Core

    Umbraco.Cms.Infrastructure

    Umbraco.Cms.Web

    Umbraco.Cms.Tests

    Code moved to new assemblies and namespaces

    The following have been moved to new assemblies and their namespaces have been updated accordingly.

    Umbraco.Extensions

    Umbraco.Cms.Web

    Umbraco.Cms.Infrastructure

    New interface methods

    A few interfaces have been merged, adding new members to the original interfaces.

    Umbraco.Cms.Core

    No-Operation methods removed

    A method not doing anything for the last couple of major releases have been removed.

    Umbraco.Cms.Core

    Changes due to models made immutable

    A single model have been made immutable, so the default constructor and the setters are not available anymore.

    Umbraco.Cms.Infrastructure

    Classes that does not inherit from base type anymore

    The following classes now directly inherit from OEmbedProviderBase instead of EmbedProviderBase.

    Umbraco.Cms.Core

    Umbraco 10

    Update 'diff' from 3.5.0 to 5.0.0

    The diff library used in the Backoffice client has been updated and introduces a breaking change since the exposed global object has been renamed from JsDiff to Diff.

    Content Schedule performance

    Removes mutable ContentSchedule property from IContent/Content to read/write content schedules.

    Use IContentService.GetContentScheduleByContentId && IContentService.PersistContentSchedule or the optional contentSchedule parameter on IContentService.Save instead.

    • Removed public methods: PublishedSnapshotServiceEventHandler.Dispose, PublishedSnapshotServiceEventHandler.Dispose(bool), and .PublishedSnapshotServiceEventHandler.Initialize.

    • Removed public ctor.

    • Some public classes in the Cms.Core.Services namespace have moved assembly from Umbraco.Cms.Infrastructure to Umbraco.Cms.Core.

    • These same public classes have changed namespace from Umbraco.Cms.Core.Services.Implement to Umbraco.Cms.Core.Services.

    NPoco types and interfaces are part of our public interface which means that this upgrade imposes breaking changes.

    • Removed support for Microsoft SQL Server Compact (SQL CE).

    • Removed ReadLock and WriteLock methods from ISqlSyntaxProvider interface. Use IDistributedLockingMechanism (or IScope which delegates to IDistributedLockingMechanism) instead.

    Added the following methods/properties to ISqlSyntaxProvider. These must be implemented in any downstream implementation e.g:

    • ISqlSyntaxProvider.HandleCreateTable(IDatabase,TableDefinition,Boolean)

    • ISqlSyntaxProvider.GetFieldNameForUpdate()

    • ISqlSyntaxProvider.GetColumn(DatabaseType,String,String,String,String,Boolean)

    Update dependency versions:

    • SixLabors.ImageSharp from 1.0.4 to 2.1.1

    • SixLabors.ImageSharp.Web from 1.0.5 to 2.0.0

    Renamed the CachedNameLength property to CacheHashLength on ImagingCacheSettings.

    Moved ImageSharpImageUrlGenerator from project Umbraco.Infrastructure to Umbraco.Web.Common and updated the corresponding namespace and DI registration (from AddCoreInitialServices() to AddUmbracoImageSharp());

    Moved ImageSharp configuration from the AddUmbracoImageSharp() extension method into separate IConfigureOptions<> implementations:

    • The middleware is configured in ConfigureImageSharpMiddlewareOptions (which also replaces ImageSharpConfigurationOptions that previously only set the default ImageSharp configuration);

    • The default physical cache is configured in ConfigurePhysicalFileSystemCacheOptions.

    This is breaking because it is no longer possible to access the properties listed below through the IMember.Properties collection. You must now access them through their specific properties that is IMember.IsLockedOut.

    • umbracoMemberFailedPasswordAttempts

    • umbracoMemberApproved

    • umbracoMemberLockedOut

    Additionally, when previously you resolved a Member as published content, all the default properties would be there twice. For instance, IsLockedOut would be there both as a property with the alias umbracoMemberLockedOut and with the alias IsLockedOut. Now it'll only be there once, with the alias being the name of the property, so IsLockedOut in this instance.

    Lastly the nullable dates on a user, i.e. LastLoginLate will now be null instead of DateTime.MinValue when getting a user with the UserService.

    Examine 3 breaking changes:

    • ValueSet immutable.

    • ValueSetValidationResult is renamed to ValueSetValidationStatus and ValueSetValidationResult is now a type.

    Has changed to:

    • Added more methods to IRedirectUrlRepository and IRedirectUrlService.cs.

    • Added a new method on IPublishedModelFactory: Type GetModelType(string? alias);

    • The generic types of a BlockListItem<TContent, TSettings>instance in theBlockListModelreturned byBlockListPropertyValueConverteris now determined by calling this new method, which can be different and cause aModelBindingException` in your views.

    Has changed to:

    StackQueue has been moved from Umbraco.Core.Collections to the Umbraco.Cms.Core.Collections namespace.

    Globalsetting SqlWriteLockTimeOut has been removed

    This setting has been superseded by DistributedLockingWriteLockDefaultTimeout.

    GlobalSetting UmbracoPath cannot be configured

    It is no longer possible to rename the /Umbraco folder path using configuration. The property still exists but is hardcoded to /Umbraco and will be removed in Umbraco 12, planned for release in June 2023.

    The choice to include Umbraco.Cms.DevelopmentMode.Backoffice depends on how you work with models and templates. It is not based in the hosting environment, and using it enables Razor runtime compilation and disables Hot Reload.

    Important! These modes do not rely on Razor runtime compilation. However, ensure the following settings are removed from your .csproj file.

    You need to be aware of some things if you are using EF Core, and have installed the Microsoft.EntityFrameworkCore.Design 8.0.0 package:

    • This package has a transient dependency to Microsoft.CodeAnalysis.Common which clashes with the same transient dependency from Umbraco.Cms 13.0.0. This happens because Microsoft.EntityFrameworkCore.Design 8.0.0 requires Microsoft.CodeAnalysis.CSharp.Workspaces in v4.5.0 or higher.

    • If there are no other dependencies that need that package then it installs it in the lowest allowed version (4.5.0). That package then has a strict dependency on Microsoft.CodeAnalysis.Common version 4.5.0. The problem is Umbraco.Cms through its own transient dependencies that require the version of Microsoft.CodeAnalysis.Common to be >= 4.8.0.

    • This can be fixed by installing Microsoft.CodeAnalysis.CSharp.Workspaces version 4.8.0 as a specific package instead of leaving it as a transient dependency. This is because it will then have a strict transient dependency on Microsoft.CodeAnalysis.Common version 4.8.0, which is the same that Umbraco has.

    Content Picker

    Schema Alias: Umbraco.ContentPicker

    UI Alias: Umb.PropertyEditorUi.DocumentPicker

    Returns: IEnumerable<IPublishedContent>

    The Content Picker enables choosing the type of content tree to display and which specific part to render. It also allows you to set a dynamic root node for the content based on the current document using the Content Picker.

    The Content Picker was formerly known as the Multinode Treepicker in version 13 and below.

    The renaming is purely a client-side UI change, meaning the property editor still uses the Umbraco.MultiNodeTreePicker schema alias.

    The change was made as the word Content in the backoffice acts as an umbrella term covering Documents, Media, and Members.

    Are you looking for the original Content Picker?

    The Content Picker from version 13 and below has been renamed .

    Data Type Definition Example

    Content Picker Data Type Settings

    Minimum/maximum number of items

    Define a limit on the number of items allowed to be selected.

    Ignore user start nodes

    Checking this field allows users to choose nodes they normally cannot access.

    Node Type

    This option allows for configuring what type of content is available when using the Data Type. The available types of content are Content, Members, or Media items.

    When selecting Content from the dropdown, the option to specify a root node, also called the origin, becomes available.

    When picking the origin there are several different options available:

    The following options are available when picking the origin:

    • Content Root: The root of the content tree.

    • Root: The root is the first level item of the sub-tree of the current node.

    • Parent: The parent is the nearest ancestor of the current node.

    • Current: The current node.

    When an origin has been specified, it becomes possible to continue to build a Dynamic Root by adding additional query steps.

    Navigate the content tree relative to the specified origin to execute multiple query steps and find the root node needed.

    The following options are available:

    • Nearest Ancestor or Self: Find the nearest ancestor or current item that fits with one of the configured Document Types.

    • Furthest Ancestor or Self: Find the furthest ancestor or current item that fits with one of the configured Document Types.

    • Nearest Descendant or Self: Find the nearest descendant or current item that fits with one of the configured Document Types.

    The options above are all based on navigating the document hierarchy by locating ancestors and descendants. It is possible to execute custom steps to build even more complex queries. Once a custom query is available it will be added to the bottom of the Append steps to query dialog. Learn more about .

    Each query step takes the output from the origin or the previous step as input. It is only ever the result of the last query step that is passed to the next step.

    Custom query steps can be used to solve specific use cases, such as traversing sibling documents or matching property values. Before the custom query steps can be selected in the Data Type settings, they must be defined via code.

    When implementing a query step it requires a collection of origins and information about the query step. The collection is taken from where the name specified in the UI can be found.

    You can inject dependencies into the constructor. These dependencies could be custom repositories or the IVariationContextAccessor, if you want to use the current culture.

    The ExecuteAsync method receives a set of content keys from the last executed query step or the origin. It has to return a new set of content keys.

    To register the custom query step, append it to the existing query steps, DynamicRootSteps(). This is done from a composer as shown below.

    Finally, register the custom query step on the client side and provide a brief description.

    You can do this in an umbraco-package.json file, as shown below:

    Choose which types of content should be available to pick using the Content Picker.

    This is done by selecting one or more Document Types.

    Consider the following tree structure where the Document Type alias is presented in square brackets.

    • Codegarden

      • 2023 [year]

        • Talks [talks]

    Consider configuring a Content Picker on the talk Document Type to select a stage for the talk. Here, you want to display only the stages for the actual year. To do this, you need to set the parent as the origin.

    For instance, if you are on the Umbraco anno MMXXIII node, the collection of content keys passed into the first query step will only contain the Talks content node.

    • First, query for the nearest ancestors of the type year. This will return 2023.

    • Second, query for the nearest descendants of the type stages.

    When opening the picker on the Umbraco anno MMXXIII node, it will now show the children of the node on the path Codegarden > 2023 > Stages.

    See the example below to see how a value can be added or changed programmatically. To update the value of a property editor you need the .

    Although the use of a GUID is preferable, you can also use the numeric ID to get the page:

    If Models Builder is enabled you can get the alias of the desired property without using a magic string:

  • A picker that uses the current node, cannot pick anything when the current node is created, as it will not have any children.

  • Site: The nearest ancestor of the current node with a domain assigned.

  • Specific node: A specific node selected from the existing content.

  • Furthest Descendant or Self:
    Find the furthest descendant or current item that fits with one of the configured Document Types.

    ...

  • Umbraco anno MMXXIII [talk]

  • Stages [stages]

    • Social Space [stage]

    • No 10 [stage]

    • No 16 [stage]

    • The Theatre [stage]

  • 2022 [year]

    • Talks [talks]

      • ...

    • Stages [stages]

      • Main Stage [stage]

      • The Barn [stage]

      • The Theatre [stage]

  • Adding a custom query step

    Specifying the origin is required for the custom query step to become available.

    Document Type Options

    Learn about the Document Type options available when you create a new Document Type in Umbraco, and when to use each one.

    When you create a Document Type in the Settings section, you choose between four options. This article describes each option and when to use it.

    Create Document Type

    Document Type

    A Document Type defines the content structure and fields that can be used across different content items. When creating a Document Type without a template, you focus solely on structured content without tying it to a specific design or layout. This is ideal for content that doesn’t require direct front-end rendering, such as blocks or items managed within a headless CMS setup.

    Use a Document Type without a template for structured, reusable content like metadata schemas, settings, or components such as product details and author profiles.

    Document Type with Template

    A Document Type with a Template combines the content structure with a predefined visual presentation. This approach links your structured content with a specific page design, ensuring a consistent and cohesive look and feel across your site. It allows you to manage content and its appearance separately, which makes updates more efficient.

    Use a Document Type with a template for pages like blog posts, landing pages, or services that appear directly on the website.

    Element Type

    An Element Type is a Document Type without a template designed for reusable and repeatable set of properties. These are used for Elements and in editors like the Block List Editor or Block Grid Editor to create structured, nested content.

    Element Types cannot render directly on the front end. When Allow in Library is enabled, Element Types can be used to create from the Library section.

    Use an Element Type when defining building blocks for complex page layouts, such as grid blocks or reusable sections. They are an essential part of modular content design.

    The Folder in the Document Types section is used to organize and structure your Document Types within the Settings section. It serves purely as an organizational container, with no impact on the Content section or site functionality.

    Use a Folder to create logical groupings, like a folder named Compositions to hold all your Composition Document Types. This makes it easier to navigate and manage your Document Types, especially in larger projects.

    Folders are a powerful tool to keep your Document Types organized and your backoffice tidy.

    Local IIS With Umbraco

    This article describes how to run an Umbraco 9 site on a local IIS server.

    This is a quick guide on getting your Umbraco website running locally on IIS.

    The guide will assume you already have IIS configured and know your way around it, as well as having a local website you wish to host.

    Setting up prerequisites

    First, you need to ensure you have "Development time IIS support installed". To check this, go to the Visual Studio installer, click modify and check on the right side under "ASP.NET and web development":

    Once that is installed you should set up a new IIS site - and make sure to add the hostname to your hosts file as well. Here is my setup for an example:

    For the path you want to point it at the root of your site - where the .csproj file is.

    Add permissions to NuGet cache folder

    You might need to change permissions for the NuGet cache folder - C:\users\<username>\.nuget\packages. The user or group (IIS_IUSRS) that the IIS site is running on requires Read permissions on this folder because this is where some of the files for Umbraco and Umbraco packages are being served from during development. If the IIS user or group does not have permission to read from the NuGet cache folder, you could run into a DirectoryNotFoundException while running the site.

    When the site is published these files are copied from the NuGet cache folder to wwwroot/umbraco and wwwroot/App_Plugins and these folders will typically have the correct permissions. For more information on setting permissions, see the article.

    At this point you can go to your Visual Studio solution of the site and in the Properties folder there is a launchSettings.json file, that looks like this:

    You can add a new profile called IIS, and point it at your local domain. Here it is with my example domain:

    At this point IIS will be added to the launch profiles, and you can run the site from Visual Studio by choosing IIS in the dropdown:

    And finally the site is running from your local IIS:

    Add new launch profile
