When I upgraded to v6 GA, that failed, leaving me with no installed copy of M365 Backup!
I restored the server from backup and tried again a few times. I couldn't get the upgrade to install.
I ended up doing a fresh installation of M365 Backup v6.
I tried to restore the configdb/proxydb data files but the service wouldn't start. I set up all 65 orgs again from scratch

Is there a supported method of performing a database backup and restore? I don't really want to go through this process again
