Yes, those are it.
Use the tool I mentioned to update that to the correct addresses on
the network, and re-try.
vdsm-tool ovn-config <engine_ip_on_net> <name of the management network>

We have a HA ovirt cluster (around 10 nodes) currently configure on the 10.8.256.x. So my question is is it possible to relocate the ovirt cluster to the 10.16.248.x. We have tried to move everything to the new network without success. All the node seem to boot up properly, our gluster storage also work properly.
