[ovirt-users] Changing CPU type from Opteron G3 to Epyc with hosted engine in 4.3

Hi! Now that I have engine and nodes on 4.3 level I'm stuck on upgrading the CPU type. I have 2 node cluster with Epyc processors. It was originally installed with 4.2 so it chose CPU type as Opteron G3 (no Epyc support back then). In Engine 4.3 Epyc is available as CPU type when I choose Compatibility Version: 4.3. Big problem is that it doesn't allow to upgrade CPU because all hosts are not in maintenance: "Error while executing action: Cannot change Cluster CPU type unless all Hosts attached to this Cluster are in Maintenance". Putting all hosts to maintenance is impossible because Engine is hosted in the cluster. I tried with Global HA maintenance, but that didn't help. What is the correct way to solve this problem?
