[ovirt-users] Re: VM migration failed after upgrade to 4.4

Live migration across major releases sounds like the sort of feature everybody would just love to have but oVirt would support as little as operating clusters with mixed release nodes. AFAIK HCI upgrades from 4.3 to 4.4 were never even described and definitely didn't involve live VMs. I exported all my VMs to an NFS based export domain, redid the HCI from scratch and then imported the VMs from the export domain. And I kept the 4.3 disks around so I could to back if things failed. The described (non-HCI) upgrade procedures had you up the creek without a paddle if things failed half-way... oVirt was never really enterprise grade.
