Upgrade done. In my case, the engine was already updated to the latest
4.x release before the hosts.
Following marks 1 and 2 works fine.
After upgrading the cluster compatibility version, got message to reboot
all the VMs.
Don't know if I really have to do that.

The following process worked for me:
1. ensure all hosts are running el7 or above, and all clusters had
been upgraded to 3.6 level
2. upgrade vdsm to 4.x on all hosts (assuming you are not using
ovirt-node) by switching to maintainance upgrading and activating one
by one to avoid VM downtime.
3. Upgrade engine by following one of the documented procedures (we
just inatalled a new machine for it and switched DNS after
backup/restore).
4. Once satisfied that illing back to 3.6 engine will not be needed -
upgrade cluster level.

Hi,
What is the best way to upgrade a datacenter from ovirt 3.6 to 4.0 ?
Upgrade engine, hosts then cluster ?
If right, how do you upgrade a host running ovirt 3.6.7 ? Simple
upgrade or fresh install ?
During the update process of a cluster, some hosts will be in
3.6.7 and others in 4.0.2, is it a problem for migrating VMs ?
Found docs about engine upgrade but not a lot about host and cluster.
Thanks,
Arnaud
