Hi there,

I'm a bit puzzled about an possible upgrade paths from a 4.3 cluster to version 4.4 in a self-hosted engine environment.

My idea was:

Set up a new host with a clean ovirt node 4.4 installation, then deploy the hosted engine on this with a restored backup from the production cluster and go from there.

This however fails with the following error:

2020-05-27 00:17:08,886+0200 DEBUG otopi.ovirt_hosted_engine_setup.ansible_utils ansible_utils._process_output:103 {'msg': 'non-zero return code', 'cmd': ['engine-setup', '--accept-defaults', '--config-append=/root/ovirt-engine-answers'], 'stdout': "[ INFO  ] Stage: Initializing\n[ INFO  ] Stage: Environment setup\n          C

Is this approach (restoring from 4.3) generally supposed to work? If not, what is the appropriate upgrade path?

Thank you!
