Umbraco 10 FAQ

The project migration from Umbraco 9 to 10 will not be like the move from version 8 to 9. The process will be more like upgrading from an old Umbraco 8 minor to the latest Umbraco 8 minor. 

In accordance with our Release Cadance, major versions will include breaking changes, but we will keep these to a minimum and add automatic migrations when possible therefore expect the move between major versions to be relatively straightforward - especially if you keep up with the cadence. 

Get an overview of the breaking change in Umbraco 10 here:

Documentation on the breaking changes will be ready by the release of the RC, targeted May 5, 2022.

On top of this, to ease your migration, please make sure that the packages you use have also been upgraded to Umbraco 10. 

SQL CE will not be supported anymore. From Umbraco 10, SQLite is a new database provider. SQL Server is still the main database provider that we recommend for production.

Furthermore, we recommend you enable Nullable reference types in your package as that will make the experience for the developers using your package better.

To help you get your packages prepared for Umbraco 10, we recommend you test it against the RC which is targeted for May 5, 2022. 

Nightly builds are also available and released regularly.
