The Error-message was: “cannot downgrade from 9.1.2.5 to 9.1.1.5” - which this user also describes: Cannot downgrade nextcloud 9.1.2.5 to 9.1.1.5 [Solution]
Is it a safe solution by changing the version in the configfile or are there safer alternatives?
When will the next NC-version be released? I have already waited a few month, and I really like to migrate asap. Obviously other users who migrate from OC 9.1.2 have the same problems?
