I answer for the upgrade of DC/Cluster level. You can upgrade DC level when you have upgraded level of all its Clusters You can upgrade Cluster level when you have upgraded all its hosts More info here: [ https://www.ovirt.org/documentation/upgrade-guide/chap-Post-Upgrade_Tasks/ | https://www.ovirt.org/documentation/upgrade-guide/chap-Post-Upgrade_Tasks/ ]
