Migrate VM to different host

[Hyien]

How can I migrate a VM to another Proxmox host that is not in the same cluster?

The easiest is to do a backup and restore.
You can manually create a VM with exact configuration, use qemu-img to export the disks and then import them.
A lot depends on the type of storage you are using.

i have a idea,
you can add a new node to old cluster,and migrate vms to this new node.
after migrate work is done, delete this node in old cluster,and join new cluster.

@bingsin Its not that simple

You may, however, get away with copying/backing up /etc/pve/nodes somewhere safe, deleting /etc/pve/nodes/*, join cluster, then copy back the /etc/pve/nodes backup you took. YMMV, and I'd suggest trying this with a demo cluster first.

This WILL NOT work wif you have VMs of the same VM ID.

The easiest way to do this without a cluster is to just use proxmox backup server. Back it up from one node and restore it to the other node.

This is now possible via qm remote-migrate as of Proxmox VE 7.3:

Hi,
thank you for pointing the documentation out. I've tried the

qm migrate

command and created another disk image with a new ID.

What I can't follow here is, how to proceed. It would be nice to document a basic example, but there isn't. Is there anybody out there who already tried this? If yes, can you please light me up how the basic steps would be? Thank in advance!

Ok, for everyone who can end up in this threat like me, I found this thread and it was very useful for me.
