Sorry. The thread became separated. Yeah. I finished the migration. Simone proposed I had
a corrupted backup. And yes. I was backtracking my backups to that point where I switched
all datacenters to 4.3 compatibility and before doing any engine migration. Lucky me, I
had that backup available.
I think my backups became corrupted, because I did a backup from the engine after I moved
it to a cluster that was originally not defined. I had a typo in the cluster name. And
used that backup and tried to get the engine back to my nfs storage. That worked. I did
another backup at that place again and from that point on the backup would always break
the deployment for whatever reason.
