What a silly choice …
your use of “silly” really irks me. I personally find it very silly to not test a migration and your backup strategy beforehand.

And I will switch my backup procedure from kopano-backup to lvm snapshot, which seems more reliable in my opinion.
You do you, but the downside of lvm snapshots is that you have to make sure that all temporary data has been written to disk before the snapshot’, else you risk creating inconsistent database records.
For a full disaster recovery I would always go for mysqldumps plus file system backups and kopano-backup to fill up any differences and be able to do partial restores for users.
