Re: [PVE-User] Moving virtual machine from CE 6.X to latest enterprise edition, advice requested

[Peppo Brambilla <peppo.brambilla@unibe.ch>]

Hi

I was using an NFS server connected to the old and new cluster. This 
should be setup as similar as possible on both cluster. Maybe it's 
sufficient if they are named the same.
Then I proceeded as follows:

* move VM's disks to the NFS share
* shutdown VM on old cluster
* copy VM's config files in /etc/pve/qemu-server/  from old to new server
* you should now see the VM on the new server as well
* start VM on new server
* move disks of VM to ceph on new server (you may want to keep the old 
disk images)
* if the VM runs fine, you can remove the config files on the old 
cluster and remove the disk images there as well)

Cheers -- Peppo
