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.

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
