Re: [ovirt-users] Unable to add Hosts to Cluster

For a proper upgrade there are specific steps that you follow for each host and the engine. I usually upgrade the hosts first then the engine. If you have spare resources so as to put hosts at maintenance then the upgrade should be seamless. Also i think you need to go strp by step: 3.5 -> 3.6 -> 4.0 ... etc In case you have a similar test setup you may try it first there.
