Hi,
maybe a stupid one. Just want to make sure that nothing goes wrong. We plan to make a rolling upgrade of our landscape going to 3.5.1 in december. So we always need some hypervisor nodes up and running during the process.
Looking at older posts I assume that upgrading the engine should be sufficient, while hypervisor nodes with vdsm 4.14.17 (from 3.4 repos) and the active VMs keep on running. The start of the engine after the upgrade should catch up and resync all states.
Afterwards I clean hypervisor hosts one by one and clean/reinstall it into the cluster?
Thanks in advance.
Markus
