My only real concern with a detach and attach is "what if" the upgrade of the storage domain does not go well, I will have to recover my entire storage from backup On Thu, Jun 1, 2017 at 2:50 PM, Yaniv Kaul <ykaul@redhat.com> wrote:

You cannot migrate VMs between Datacenters. I think an export domain will be your easiest option but there may be a way to upgrade in-place (ie. upgrade engine while vms are running, then upgrade cluster) but I am not an expert in this area.
Why is an export domain better than detach and attach a storage domain? Y.

I couldnt find a definitive on this so I would like to inquire here
I have gluster on my storage backend exporting the volume from a single node via NFS
I have a DC of 4.0 and I would like to upgrade to 4.1. I would ideally like to take one node out of the cluster and build a 4.1 datacenter. Then live migrate VMs from the 4.0 DC over to the 4.1 DC with zero downtime to the VMs
Is this possible? Or would I be safer to export/import VMs?
Thanks!
