while within the HostedEngineLocal engine.log:

Why is the playbook trying to migrate HostedEngineLocal from reinstalled 4.4.3 oVirt node to an existing one that is still running oVirt Node 4.3.x ?
How can we manage this issue and proceed with the upgrade ?


Thanks is advance for support.
Best regards
