you are righ, there is a tooltip explaining tha I have to shutdown all vms before changing compatibility version (I suppose this is valid only for 3->4 upgrade because minor upgrades were possible without downtime)
1. DC is at 3.6 and you can't have 4.0 clusters in 3.6 DC.
but when I try to change DC version from 3.6 to 4.0 I got"Error while executing action: Cannot update Data Center compatibility version to a value that is greater than its Cluster's version. The following clusters should be upgraded CIT-oVirt."
2. Active host on 3.6 in the cluster. You can put the hosts in maintenance and upgrade the cluster, you will obviously also have to upgrade the hosts after that before you can activate them again.
ok, thanks for help. I have to schedule maintenance window. Cheers, Jiri

Then I upgraded all hosts in cluster and I would like to change cluster compatibility level but it fails in a way there is a red border around "Compatibility Version" dropdown box but no explanation why. There are no entries in logs... What are prerequisities to change cluster compatibility level to 4.0? Do I missing something? Engine (standalone) and hosts are CentOS 7.2 btw. dashboard looks really nice!
