If you upgrade to v12.5 form a version < 12.4 and use MS SQL Server, the upgrade will fail and your application could end up in an inconsistent state.
If this happens, you need to rollback using a files + DB backup.
The issue is present if you use the standard up/up2 approach, while the old upgrade/upgrade2 approach works.
