If unity Connection Subscriber Database is corrupt
Note, not the CUCM database on the CUC server, but the CUC database). On the subscriber, run the below command

utils cuc cluster overwritedb

Error: “Sync after Swicth version failed”

Run the following command on the cuc publisher:

utils os secure permissive

This is also needed (I believe - need to test) if you want to do a VMware Tools update on recent Cisco VOS

the show version active is not displaying the software options that were installed succesfully. This is caused by a permission bug (which seems to occur on the publishers) and needs TAC / root access to correct

admin:show version active
Active Master Version: 11.0.1.24900-2
Active Version Installed Software Options:
No Installed Software Options Found.

Fixed by running the command (via TAC Root Access)

chmod a+x installed_options/
