Version Specific Upgrades

This document covers specific upgrade steps if a version requires them. Most versions do not require specific upgrade steps. In most cases, you will be able to upgrade directly from your current versi
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.
Breaking changes
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 Umbraco Announcements repository.
The full list of API-breaking changes can be found below.

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 redundant event handling code​
Removed public methods: PublishedSnapshotServiceEventHandler.Dispose, PublishedSnapshotServiceEventHandler.Dispose(bool), and .PublishedSnapshotServiceEventHandler.Initialize.
Removed public ctor.
​Scope provider cleanup​
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.
​Update to NPoco5​
NPoco types and interfaces are part of our public interface which means that this upgrade imposes breaking changes.
​SQLite support​
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.
Constants for SQL Server provider name moved+consolidated from Core.Constants.DatabaseProviders and Core.Constants.-DbProviderNames to Umbraco.Cms.Persistence.SqlServer.Constants
Some SQL Server related services moved from the Umbraco.Infrastructure project to the new Umbraco.Cms.Persistence.
SqlServer project with altered namespaces e.g. SqlServerSyntaxProvider, SqlServerBulkSqlInsertProvider, SqlServerDatabaseCreator.
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)
ISqlSyntaxProvider.InsertForUpdateHint(Sql)
ISqlSyntaxProvider.AppendForUpdateHint(Sql)
ISqlSyntaxProvider.LeftJoinWithNestedJoin(Sql,Func<Sql,Sql>,String)
​Update to ImageSharp v2​
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.
