Move 600Gig vm from 3.4 to 5

[ehabh]

I have a 600+ gig vm and I want to move it from an old 3.4 proxmox server to a newer 5.1 proxmox server in the same data center. What is the best or fastest way to do this?

depends on details and your possibilities in the datacenter.

e.g. use backup/restore or if you VM is on a single disk, just connect this disk on the new host.

1. Mount the same nfs server on each proxmox node (on v3.4 and on v5.1).
2. Move disk of the vm from the usually storage you are using on prox 3.4 to the nfs server.
3. Copy the vm conf (/etc/pve/qemu-server/) from the prox 3.4 to prox 5.1
4. Power down the vm on prox 3.4
5. Power up the vm on prox 5.1
6. Move disk from the nfs to the node storage you are usually using on prox 5.1

The disk is on lvm can you move that?

 

[Dan Nicolae]

Yes. Click on the node, click on the VM you want to move, go to hardware, select the VM disk, click on the button above called Move disk, select Target Storage (in this case, the nfs server) and hit Move disk.
