Jiri
The label that has the dotted line under it should have a tooltip expla=
ining
the issue. But some of the most likely issues are:
you are righ, there is a tooltip explaining tha I have to shutdown all=20
vms before changing compatibility version (I suppose this is valid only=20
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=20
version to a value that is greater than its Cluster's version. The=20
following clusters should be upgraded CIT-oVirt."
...
2. Active host on 3.6 in the cluster. You can put the hosts in maintena=
nce 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

custom certificate problem which is described and solved here
https://bugzilla.redhat.com/show_bug.cgi?id=3D1336838).
Then I upgraded all hosts in cluster and I would like to change clust=

compatibility level but it fails in a way there is a red border aroun=

"Compatibility Version" dropdown box but no explanation why. There ar=

What are prerequisities to change cluster compatibility level to 4.0?=
 Do
