How to migrate VMs to new CEPH Cluster?


Sep 25, 2019
Hey, we build a new PVE ceph cluster and would now migrate all VMs from our old cluster.
In our old one we have ZFS and directory based storage (raw and qcow2 disks) mixed.
How can we do this? We already tested "qm remote-migrate" but this seems unable to migrate ZFS to CEPH Storage.
Is our only option to backup all the VMs and resore on the new cluster?
I would just backup them on your old cluster and restore them on your new one.

Hook up an USB harddrive, mount it as a backup store. Shut down the old VMs, then backup them onto your USB datastore. The backup/restore operations use the corresponding storage and you dont have to think much about from what to what storage you are migrating.
