Moving VM and Disk to new cluster

[Calanon]

Hi there,

I have two proxmox clusters each with their own ceph clusters attached. I want to move VMs one by one from one cluster to another. I understand normally this can be achieved with a backup and restore to and from a mounted disk but what if I do not have enough space on the backup target to facilitate this?

If I am wrong I would be welcome to any insights.

Does anyone have any ideas or experience with this?

Hi,

I would pipe a backup into a restore over ssh.

ssh into the target machine (make sure you can passwordless ssh to your source machine) and use the following command (change this to your setup accordingly):

ssh 10.1.13.2 'vzdump 100 --mode stop --stdout' | qmrestore - 105 --storage local-zfs
