Hi everyone Im having issues with upgrading from umbraco 13 to 14. I’ve been searching and cant seem to find a solution for it. I can skip the migration, but further down the line Im getting more migration issues, and im wondering if it could be other umbraco 13 migrations that hasnt run correctly.…

Why are you upgrading to Umbraco 14 and not 17? You can do a direct upgrade to 17. 14 has some issues and is completely out of support.

Hi @dennispedersenakqa Please see my comment on the other thread to see if that helps. [image] Umbraco upgrade from U13 to U14, returning 401 error speech_balloonQuestions Hi @Ajeetkmr154 You will need to using something like uSync Migrations to migrate Nest…

You will also need to be on the latest v13 version before moving onto v17 once you have migrated the data as mentioned.

Ah. I was under the impression that we shuold do one version at a time. After switching to 17.4.2 it seems to work. Thank you!

I understand that feeling :slight_smile: However, even the migrations sometimes have mistakes that get fixed in later versions. I think the migration 13 > 17 is much better than 13 > 14 or 13 > 15. As you found out :wink:

Im honestly a bit scared it went so smoothly haha. Now its time to comment in the custom code again.
