There are a multitude of options for migrating away from macros to use blocks in the Rich Text Editor instead. This article showcases a solution that lets you scan and then fix each macro one by one (or in batches).
This tutorial serves primarily as inspiration for how to migrate the macros in your Umbraco website.
The code supplied should not be used in a production environment without proper testing. It can however be used to kickstart your custom solution.
At the end of the article a few .
Through the following tutorial, a macro will be converted one-to-one to a block. Each macro parameter will match the same named property on an Element Type. Text strings will be used as values.
If your migration deals with complex types, it's advised to create instances of the new data format and compare the old and new values. There might be more differences between the Parameter Type on the macro and the Property Editor/Data Type on the Element Type.
Upgrading from Umbraco 13
As most people will be dealing with this migration when upgrading from Umbraco 13, that will be including in this tutorial. Specifically from 13.7.2 to 15.2.3.
This will also work when migrating directly from 13 to 17.
Macro setup
The following covers how to configure a macro.
You need to:
Define a macro and its parameters.
Have a macro partial view that is used to render the macro on the website. It is also used in the backoffice rendering if enabled in the macro settings.
Transform the macro view in to a Richtext block view.
@inherits Umbraco.Cms.Web.Common.Views.UmbracoViewPage<Umbraco.Cms.Core.Models.Blocks.RichTextBlockItem>
@{
var blockValue = Model.Content as CtaBlock;
}
<div class="Button">
<a href="https://www.youtube.com/watch?v=@blockValue.YoutubeVideoId">@blockValue.Title</a>
</div>
The core conversion
However you retrieve the relevant data you have with a raw string or a RichTextEditorValue that you need to convert. The following looks at a sample value.
The markup with the actual RTE value and the inline macro data.
The macro consists off:
The tag used as a placeholder where to render its output.
An alias to find the correct render/update logic.
Two parameters with values entered by the user.
The first step in transforming the data is taking the JSON value and deserializing it into a RichTextEditorValue. This way you have a class to work with to store the updated data in.
You can deserialize it yourself, or you can use the RichTextPropertyEditorHelper to do the job for you. It will also try to catch non-JSON values that have not been migrated to the new format.
Usage of RichtextPropertyEditorHelper
RichTextPropertyEditorHelper.TryParseRichTextEditorValue(originalValue, _jsonSerializer, _logger, out var richTextEditorValue);
The next step is to get all (relevant) macro tags out of the markup. One way of doing this is through a regular expression.
The sample regex does not take into account that the order of parameters, which might be different from tag to tag. One way of dealing with this is to not take out the parameters in the first match. Instead move each parameter to a separate regex that runs on the first match.
Example regex
// this regex does not take into account that the parameters might be in a different order.
private static readonly Regex MacroTagRegex = new(
@"<\?UMBRACO_MACRO\s+macroAlias=['""](?<macroAlias>.+)['""]\s+title=['""](?<title>.+)['""]\s+youtubeVideoId=['""](?<youtubeVideoId>.+)['""]\s*/>",
RegexOptions.IgnoreCase | RegexOptions.IgnorePatternWhitespace | RegexOptions.Multiline);
Every macro conversion will be different based on which parameters get matched to which properties on the block. As such it is advised to create a converter per macro that deals with the specific data handling.
Now that the relevant information has been extracted, it's time to decide what the data should look like.
The markup still contains a tag placeholder but this time with only the data-content-key.
That key references an item inside the blocks contentData that holds the values of the properties and a reference to the Element Type set up earlier.
The same key is added to the expose collection and the Rich text layout collection.
This means that if you have multiple blocks in the same value, more contentData items will be added in the blocks collection. They will be referenced in the expose and Layout accordingly.
The example below shows the full handling of an invariant macro to an invariant block.
This migrator starts and ends with a raw (serialized) string. If you choose a different path, you might have to change the code to work with the supplied value types instead.

PropertyType = new PropertyType(_shortStringHelper,Constants.PropertyEditors.Aliases.TextBox, ValueStorageType.Nvarchar)
};
}
Retrieving the data
This example also only fetches the active (draft/current) version of the affected data to reduce processing time.
Putting the updated value back
Once the data is transformed it needs to be stored. Custom SQL is used to perform this.
If you need to perform validation on the updated value, you either have to use a higher level services (IContentValidationService/IContentEditingService) or use the RichTextPropertyValueEditor.Validate() method. Because this example fetches the current data and overwrites it, the old value will not show up in the version history of the affected node. If you do need this to happen then it is advised to use the IContentValidationService or IContentService instead.
Now that you have a converter you need a way to call the correct one depending on the macros found in an RTE value. For this, create a MacroMigrationService that holds the following method:
public void Migrate(IEnumerable<int> PropertyDataIds)
{
using IScope scope = _scopeProvider.CreateScope(autoComplete: false);
// get the necessary data from the database, just the Id and propertyValue.
var itemsToProcess = scope.Database.Fetch<MacroPropertyDto>(@"
select pd.id as propertyDataTypeId,
pd.textValue as PropertyValue
from umbracoPropertyData pd
where pd.id in (@0)",PropertyDataIds);
foreach (var item in itemsToProcess)
{
// a value might have multiple values
var macroMatches = MacroTagRegex.Matches(item.PropertyValue);
foreach (Match macroMatch in macroMatches)
{
// for every macro find a matching migrator and run it
var migrator = _migrators.FirstOrDefault(m => m.MacroAlias == macroMatch.Groups["macroAlias"].Value);
if (migrator == null)
{
continue;
}
item.PropertyValue = migrator.Process(item.PropertyValue);
}
// save the value back to the database
scope.Database.Execute(@"
update umbracoPropertyData
set textValue = @0
where id = @1"
,item.PropertyValue, item.PropertyDataTypeId);
}
scope.Complete();
}
The method above takes in an IEnumerable<int>. How to get those will be determined later.
To access the database, you need a scope from the scope provider.
The next step is to fetch the value from the database using our custom MacroPropertyDto and a custom SQL query.
For each of the items found, run a regular expression that matches on the tag and alias.
The next step is to look in the list of migrators to find the correct one based on the alias found in the match. Then this needs to run.
When all macros have been converted for a given property, the updated value is saved in the database.
To get all the property IDs, the following Report method is used. The method returns a paginated report of all items that need to be migrated. It includes relevant document data and which migrator will run. This allows you test and debug specific values and migrators.
public MacroMigrationReport Report(int page, int pageSize)
{
using IScope scope = _scopeProvider.CreateScope(autoComplete: true);
// page query all propertyValues in DB that are of type Umbraco.RichText with the textValue like '%<?UMBRACO_MACRO%/>%'
var count = scope.Database.ExecuteScalar<int>(CountQuery);
var pagedItems = scope.Database.Fetch<MacroPropertyDto>(page, pageSize, FetchQuery);
var report = new MacroMigrationReport
{
Page = page,
PageSize = pageSize,
TotalItems = count,
};
// for the paged items
foreach (var macroPropertyDto in pagedItems)
{
var reportItem = new MacroMigrationReportItem
{
PropertyDataId = macroPropertyDto.PropertyDataTypeId,
ContentName = macroPropertyDto.ContentName,
ContentType = macroPropertyDto.ContentTypeAlias,
PropertyAlias = macroPropertyDto.propertyTypeAlias,
};
// add converterInformation, create an entry for each occurance of the UMBRACO_MACRO tag
var macroMatches = MacroTagRegex.Matches(macroPropertyDto.PropertyValue);
foreach (Match macroMatch in macroMatches)
{
var macroInfo = new MacroInfo
{
MacroAlias = macroMatch.Groups["macroAlias"].Value
};
var migrator = _migrators.FirstOrDefault(m => m.MacroAlias == macroInfo.MacroAlias);
macroInfo.MacroConverter = migrator?.GetType().Name;
macroInfo.TargetBlockContentTypeKey = migrator?.TargetBlockContentTypeKey == Guid.Empty
? null :
migrator?.TargetBlockContentTypeKey;
reportItem.FoundMacros.Add(macroInfo);
}
report.Items.Add(reportItem);
}
return report;
}
The last steps are to:
Register the services and their interfaces into the DI container using a composer.
Create a management API controller to call the service.
A full list of files including the full version of the MacroMigrationService and its dependencies can be found below. Once all of this is in place you will have some Swagger docs available at /umbraco/swagger/index.html?urls.primaryName=Macro+Migrations+Api+v1 to test the migrators.

Alternative approaches
Using Umbraco migrations
The proposed conversion logic should be adaptable to the system used in the local links migration.
Using Umbraco Deploy
If you are using Umbraco Deploy in your solution, you can use its infrastructure to run the migration logic defined above.
In this setup, the values are received straight from the database using custom Data Transfer Objects (DTOs). This allows for getting get the data needed. This example does not take nested data into account. For an example on how to to do this, at the bottom of this article.
If you want the conversion to happen automatically as you upgrade, you can define a
For an example that takes into account RTE values inside of block properties, have a look at our and its related
To make this work, update the alias of the rich text editor to something else. On import, a migration is triggered. See the in the Umbraco.Deploy.Contrib package.
Create a migrator to handle any value that is of the special alias and convert them into a property with the updated value. For an example see the matching .
