[ovirt-users] Re: oVirt 4.2 cluster upgrade
The upgrade selection would only upgrade you to the last version of 4.2 if
that is even out there for it to download.
4.2 has been end of life for a long time now.
You need to upgrade the engine itself to at least 4.3.10 to upgrade to 4.4,.
So much has changed internally with 4.2 to 4.3 to 4.4, (4.4 is based on
CentOS8, etc.) that a simple yum
update won't do it. For that big of a jump you might want to save off the
VM images somewhere external
and redeploy as a new 4.4 cluster and import the images into the new
cluster.

I have a 3 node oVirt 4.2.1 cluster,
i'm using a self-hosted engine architecture and
storage-engine is on a glusterfs replica 3
of the cluster.
The oldest CPU is SandyBridge family (E5-2609)
and incidentally I have connectivity problems with IPMI NIC of one node,
but Hosted Engine HA is enabled and working.
Is it safe to upgrade to the last oVirt 4.4 without a down of vm running
on the cluster?
May I just click on the button
Upgrade
that appears on the host page?
