[ovirt-users] Add nodes to single-node hyperconverged cluster

Hi, I'm currently running an out-of-date (3.6) 3-node oVirt cluster, using NFS storage. I'd like to upgrade to the latest release and move to a hyperconverged setup, but I've only got the three hosts to play with. I'm currently thinking of pulling one node from my current cluster, rebuilding it to start a new cluster, and then migrating VMs/physical hosts over to the new cluster. Is that something that would seem feasible? I've read the documentation on setting up a hyperconverged cluster, but didn't see anything about adding new hosts after cluster deployment.Thanks! Joe
