[ovirt-users] Re: Need advice before building a new oVirt Environment
Hi,
Afaik you can't move vm's between 2 datacenters, because it's storage is
completely separated from each other.
So what I would do is just create a new cluster with the new servers,
but in the same datacenter so it shares it's storage domains with the
current cluster.
Then attach the netapp to the datacenter when received, and then you can
migrate the storage to the netapp first and then shutdown the vm, move
it from cluster, and boot it.
Or you shutdown the vm first, move it to the new cluster, and do the
storage migration to netapp there.

months to arrive. In the meantime, I have to create various VMs in my existing
