Our Umbraco

Umbraco CMS is a flexible and editor-friendly Content Management System (CMS) that allows you to create beautiful and modern websites. Use the latest version of .NET, integrate with your favorite services, and help your customers launch a website tailored to their specific needs.

The documentation for Umbraco CMS provides information for experienced Umbraco and .NET developers. It also offers guides and high-level articles for people starting out with the CMS.

Umbraco Training

We have made custom Umbraco templates that are available for use with dotnet new. The steps below will demonstrate the minimum amount of actions required to get you going and set up an Umbraco project from the command line using .NET templates.

Video Tutorial

Install the template

To get help on a project template with dotnet new run the following command:

dotnet new umbraco -h

From that command's output, you will get a better understanding of what are the default template options, as well as those command-line flags specific to Umbraco that you can use (as seen below):

Create an Umbraco project

1. Create a new empty Umbraco solution: dotnet new umbraco -n MyCustomUmbracoProject

You will now have a new project with the name MyCustomUmbracoProject, or the name you chose to use. The new project can be opened and run using your favorite IDE or you can continue using the CLI commands.

Run Umbraco

1. Navigate to the newly created project folder: cd MyCustomUmbracoProject

2. Build and run the new Umbraco .Net Core project: dotnet build dotnet run

The next step is to run through the Umbraco CMS installation. If you chose to use MS SQL Server/Azure you will need to add your connection string during this setup process to get access to the Umbraco backoffice.

Prerequisites

Quick Start

• Open Visual Studio.

• Go to File > New > Project, search for Umbraco.

• Choose Umbraco Project (Umbraco HQ) then click Next.

• Choose or specify the parameters, leave the default or leave them all empty.

• Click Create.

• Use CTRL+F5 to run the project and start the Umbraco installer.

Video Tutorial

Create a new Umbraco project

To install Umbraco we first need to install Umbraco's dotnet new templates.

Create the Visual Studio project

Go to File > New > Project and search for Umbraco in the Search for templates field.

Once you select Umbraco Project (Umbraco HQ) navigate to the next step by clicking Next.

Configure project

In this step, you will be able to give your project a name specific to the project you are creating.

Additional information

In the next step, you are able to specify some additional parameters like the Target framework. The rest are optional.

You can then click the Create button and your Umbraco Project will be ready for you.

Running the site

You can now run the site through Visual Studio using F5 or the Debug button.

Follow the installation wizard and after a few steps, you will get a message saying the installation was a success.

Next steps

You are now ready to start building your Umbraco project. Have a look below for different resources on the next steps.

Browsers

The Umbraco UI works in all modern browsers:

• Chrome (Latest)

• Edge (Chromium)

• Firefox (Latest)

• Safari (Latest)

Local Development

Below you can find the minimum requirements to run Umbraco 15 on your machine:

• One of the following .NET Tools or Editors:

Hosting

Recommendation requirements to run Umbraco

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 to be on the latest and supported Microsoft versions to run and host Umbraco CMS:

Other recommendation

• 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.

Database Account Roles

The database account used in the connection string will need permission to read and write from tables. It will also require permission to create 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.

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:

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.

Add new launch profile

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:

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

Prerequisites

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

• .NET SDK with Umbraco Templates v15 or higher

• Docker Desktop

Installing

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

Option 1: Using SQL Server

1. 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

    • .dockerignore

  • .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.

Option 2: Using SQLite

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.

Useful Commands

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.

Bind Mounts (SQL Server setup)

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.

Template Options (SQL Server only)

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.

Install the latest .NET SDK

Before you install Umbraco, you must ensure that you can run it on your machine.

Install Umbraco using CLI

The fastest way to get the latest version of Umbraco up and running is by using the command line (CLI).

1. Open your command line.

2. Install the Umbraco templates:

1. Create a new project:

1. Navigate to the newly created project folder. It will be the folder containing the .csproj file:

1. Build and run the newly created Umbraco site:

1. The console will output a message similar to: [10:57:39 INF] Now listening on: https://localhost:44388

1. Open your browser and navigate to that URL.

2. Follow the instructions to finish up the installation of Umbraco.

Alternative Methods for Installing Umbraco

There are numerous ways to install Umbraco. Below, you can find links to different installation methods that will help you easily install and set up Umbraco projects.

.NET CLI, included with the .NET Software Development Kit (SDK), can be used to install or uninstall .NET templates from NuGet. This can be done by using the dotnet new command on any OS. The underlying Template Engine enables the creation of custom templates which make new project bootstrapping much faster. With a few steps you can have an Umbraco project running without the need for a code editor.

Visual Studio is used to write native code and managed code supported by .NET and many others. Its built-in tools provide the ability to develop and execute applications for any platform. Developers will be able to install Umbraco without ever having to leave Visual Studio.

Learn how to run an already installed local installation of Umbraco.

Visual Studio Code is an editor with an embedded webserver (through the IIS Express extension). A fast way to get you up and running with Umbraco.

From Umbraco v9 and above you can use the Nightly Builds to get the latest version to use and test before it is released. Learn how to install the Nightly builds to get started.

Since Umbraco 9 it has been possible to run Umbraco CMS natively on Linux or macOS High Sierra. To get Umbraco running you will need to follow some steps.

Use the Unattended installs when spinning up Umbraco instances on something like Azure Web Apps to avoid having to run through the installation wizard.

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

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

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).

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

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

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.

• Add the connection string using configuration.

SQL Server Example in appsettings.json

SQLite Example in appsettings.json

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.

Enable the unattended installs feature

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 keys for this would then be as follows:

Initialize the unattended install

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.

Configuration options

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.

More support

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:

CLI

Visual Studio

Follow these steps to set up an Umbraco project with VS Code. The benefit of using VS Code is that it is super quick to get up and running.

Installing and setting up VS Code

2. Once installed, launch VS Code.

3. Click the extensions menu at the bottom on the left side. Then search for C# and install it.

Creating your Umbraco project

Configure VS Code to run the Umbraco project

Open your project folder in VS Code, your project will look something like this:

Now we need to tell VS Code how to run your project.

Open the command palette, you can use the shortcut Ctrl+Shift+P, and type in Tasks: Configure and select the Tasks: Configure Task option:

Select "Create task.json from template"

Now select ".NET Core" as your template.

After this VS Code will have created a folder called .vscode that contains a file called tasks.json, it's this file that tells VS Code how to build your project.

Now that we've told VS Code how to build your project, we need to tell it how to launch it. VS Code can do this for you. First, select the little play button in the left side menu, and then select the "create a launch.json file" link.

This will prompt a menu to appear, select .NET 5+ and .NET Core:

Now you'll see a green play button appear with a dropdown where ".NET Core Launch (web)" is selected.

If you navigate to the Files section, a new launch.json file is created in the .vscode folder. When you press F5, the launch.json file tells VS Code to build your project, run it, and then open a browser .

With that, you're ready to run the project! Press F5, or click the little green play button in the Run and Debug section to run your brand new Umbraco site locally.

Umbraco Web Installer

This section continues from where we left off but covers the installation and configuration of Umbraco inside your web browser when you run Umbraco for the first time.

You will see the install screen where you will need to fill in some data before Umbraco can be installed.

When the installer is done, you will be logged into the backoffice.

Congratulations, you have installed an Umbraco site!

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.

What are the limitations?

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

Versions supported

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.

Database types supported

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.

Known issues

Feedback from user testing has shown that some databases are harder to migrate than others.

Third party property editors

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.

[RuntimeLevel(MinLevel = RuntimeLevel.Upgrade, MaxLevel = RuntimeLevel.Upgrade)] // only on upgrades
public class PreValueMigratorComposer : IUserComposer
{
    public void Compose(Composition composition)
    {
        composition.WithCollectionBuilder<PreValueMigratorCollectionBuilder>()
            // Append all of the migrators required
            .Append<MyCustomPreValueMigrator>()
            .Append<AnotherPreValueMigrator>();
    }
}

What will happen

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

How it works

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

Step 1: Upgrading to 7.14+

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

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

Step 2: Migrating content to Umbraco 8

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.

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.

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:

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

Step 3: Files migration

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.

Step 4: Post-migration checks

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.

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.

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:

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;
        });
}

Opting out of the content migration

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:

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;
        });
}

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:

In this article, you will find everything you need to upgrade your Umbraco CMS project.

You will find instructions on how to upgrade to a new minor or major version as well as how to run upgrades unattended.

Before you upgrade

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

• 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.

• 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 download page, in the Project compatibility area, click View details to check version-specific compatibility.

Legacy Umbraco

The steps outlined in this article apply to modern Umbraco from version 10 and later versions.

Are you upgrading to a minor for Umbraco 6, 7, or 8 you can find the appropriate guide below:

Upgrade to a new Major

You can upgrade to a new major of Umbraco CMS directly by using NuGet.

Choose the correct .NET version

Use the table below to determine which .NET version to upgrade to when going through the steps below.

Upgrade your project 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 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.

5. Go to Tools > NuGet Package Manager > Manage NuGet Packages for Solution...

6. Go to the Installed tab in the NuGet Package manager.

7. Upgrade Umbraco.Cms.

   a. Select the correct version from the Version drop-down.

   b. Click Install to upgrade your project.

1. Make sure that your connection string has TrustServerCertificate=True in order to complete the upgrade successfully:

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

1. Restart your site in IIS, then build and run your project to finish the installation.

Upgrade to a new Minor

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:

<ItemGroup>
  <PackageReference Include="Umbraco.Cms" Version="x.x.x" />
</ItemGroup>

Run an unattended upgrade

When upgrading your Umbraco project, 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.

Enable the unattended upgrade feature

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

2. Set the value of the key to true.

{
    "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 Runtime level will use Run instead of Upgrade to allow the website to continue to boot up directly after the migration is run. This happens instead of initiating the otherwise required restart.

Unattended upgrades in a load balanced setup

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

2. Deploy to all environments.

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

4. Boot the Main server and the upgrade will run automatically.

5. Wait for the upgrade to complete.

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

Note

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.

Contents

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

Upgrade using NuGet

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

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

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.

Upgrade manually from a zip file

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

• /bin

• /Umbraco

Merge configuration files

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

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.

Merge UI.xml and language files

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).

Finalize

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.

Run an unattended upgrade

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.

Enable the feature

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

2. Set the value of the key to true.

    <add key="Umbraco.Core.RuntimeState.UpgradeUnattended" value="true" />

Check the ConfigurationStatus

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.

<add key="Umbraco.Core.ConfigurationStatus" value="x.x.x"/>

Run the upgrade

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

Boot order

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.

Unattended upgrades in a load balanced setup

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.

Post installation

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

Potential issues and gotchas

Browser cache

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.

In this article you will find instructions for 2 different ways of upgrading:

Upgrade using NuGet

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

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

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.

Upgrades to versions lower than 7.2.0

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).

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.

Upgrade manually from a zip file

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

• /bin

• /Umbraco

• /Umbraco_Client

Merge configuration files

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

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.

Merge UI.xml and language

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).

Finalize

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.

Post installation

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

Potential issues and gotchas

Browser cache

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.

This section describes best practices with running Umbraco on Azure Web Apps

What are Azure Web Apps

They have been called a few names in the past, many people still know Azure Web Apps as Azure Web Sites.

App Service is a fully Managed Platform for professional developers that brings a rich set of capabilities to web, mobile and integration scenarios. Quickly create and deploy mission critical web Apps that scale with your business by using Azure App Service.

Umbraco will run on Azure Web Apps but there are some configuration options and specific Azure Web Apps environment limitations to be aware of.

Recommended configuration

You need to add these configuration values. E.g in a json configuration source like appSettings.json:

You can also copy the following JSON directly into your Azure Web App configuration via the Advanced Edit feature.

Remember to add an ASPNETCORE_ENVIRONMENT variable with values Development, Staging, or Production.

The minimum recommended Azure SQL Tier is "S2", however noticeable performance improvements are seen in higher Tiers

Storage

It is important to know that Azure Web Apps uses a remote file share to host the files to run your website. This is due to the files running your website do not exist on the machine running your website. In many cases this isn't an issue. It can become one if you have a large amount of IO operations running over remote file-share.

Issues with read-only filesystems

Scaling

Web worker migrations

It's important to know that Azure Web Apps may move your website between their 'workers' at any given time. This is normally a transparent operation. In some cases you may be affected by it if any of your code or libraries use the following variables:

• Environment.MachineName (or equivalent)

When your site is migrated to another worker, these variables will change. You cannot rely on these variables remaining static for the lifetime of your website.

How to find the Linux App Service Logs

The quickest way to get to your logs is using the following URL template and replacing {app} with your Web App name:

https://{app}.scm.azurewebsites.net/api/logstream

You can also find this in the KUDU console by clicking Advanced Tools > Log Stream on the Web App in the Azure Portal.

Web App secret management

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.

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

Configuration changes

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

• /web.config updates

  • 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:

    • Remove the section name="BaseRestExtensions" section

  • The inlinepopups is compatible and supported in Umbraco 7. You need to remove these elements: plugin loadOnFrontend="true", inlinepopups/plugin;

  • The plugins element that is shipped with Umbraco 7 looks like this:

    • You need to merge the changes from the new tinyMceConfig file into yours. The command elements that have changed are: JustifyCenter, JustifyLeft, JustifyRight, JustifyFull, umbracomacro, umbracoembed, mceImage, subscript, superscript, styleselect

    • Remove the command: mceSpellCheck

• /config/dashboard.config
