Hi,
i'm running an ovirt cluster in 3.6 (centos 7) no hosted engine.
Is it possible to upgrade directly from 3.6 to 4.1? Or this is not recommended.
Thanks,
Lionel

It's not possible. You need to go through 4.0.
Best,
Thanks,
Lionel

A Few weeks ago I did upgrade from 3.5 to 4.1
The release-by-release (3.5 -> 3.6 -> 4.0 -> 4.1)upgrade we found out as
very time consuming, since we were running CentOS 6 on all HOST and
Engine too. We decided to install new 4.1 and migrate the VM.
The only disadvantage of this upgrade is the VM downtime during the
migration. You need to export and import them again.

Agree, it takes time - but there is the InCluster migration policy which
allows mixing (in a single direction - EL6 -> EL7) hosts, especially to
prevent downtime.
The only disadvantage of this upgrade is the VM downtime during the
migration. You need to export and import them again.
What about detach and attach the storage domain? Wasn't that a viable
option? Or did you prefer export-import one (or several) VMs at a time?
