The issue you are facing:
Forced upgrade to NC 28. Now several key apps I use is not supported yet.
But most critical is the forced upgrade.
I entered my instance through a browser, and was meet by the “several apps needs to be upgraded” and the button, and I could not ignore this one.
As I uses snapshotting I just gave it a try using occ upgrade. Alas it ended up in an internal server error.
I then reverted to the snapshot of the same morning, so I was now again at the “forced” upgrade screen. This time I ran my full update and upgrade script, and it patched my NC to version 28.0.0. No error 500 this time, but many of my most used apps did not yet have a supported version. So I reverted to the snapshot of yesterday (still forcing my to “upgrade”). I reverted to a snapshot one day peior to that: Same enforcement. In order to prevent loosing any data and for the sake of the unconvenience of my users if I had to revert to older snapshots yet again and then had to restore “newer” files and passwords etc, I decided to run my script to update/upgrade to NC 28. It does work, but I am mostly concerned with the forced upgrading.
