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

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."
