Hi! We have installed our test infrastructure on 4 Centos hosts. Our self-hosted engine further manages serveral stand alone hosts as separate datacenters. We'd like now to reinstall the whole thing in a best practice way with oVirt node and a fresh hosted engine. We have planned to: - set up 2 of the 4 hosts with ovirt node - shut down the old hosted engine - set up the new hosted engine with the same name - move the VM's from the old cluster to the export domain in a maintenance windows - import the VMs to the new cluster - attach the stand alone hosts to the new hosted engine in again separate datacenters Is this way possible to go or are there other ways e.g. without the need of a maintenance window? Thanks for your thoughts!
