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

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

Thank you!

Regards
Oli
