Hi,
thanks to both - downgrading did not work, there is too much that needs to
be removed and the old repos are deprecated and only available via eus. So,
I'll setup the three node first and try to import the old domain there.

Is 4.3 and RHEL hosts also a good option, or is there something specific
in 4.2 that makes 3.6 domains better to import/attach?
In 4.3 we completely removed the support for 3.6 and 4.0 datacenter/cluster
levels as for:

No way using 4.3 stuff (that's why we also removed --upgrade-appliance from
hosted-engine in 4.3).
Your only option now is to use 4.2 only repos with oVirt or RHV-H from 4.2
if on RHV.
