Since the FQDN is not changing you should not have issues just updating
your DNS then changing manually the engine IP from the ifcfg-ethx files
then restart networking.
What i find difficult and perhaps impossible is to change engine FQDN, as
one will need to regenerate all certs from scratch (otherwise you will have
issues with several services: imageio proxy, OVN, etc) and there is no such
procedure documented/or supported.
I might be able to soon test this engine IP change in a virtual
environment and let you know.
I followed the following steps to change engine IP and had no issues:
1. enable global maintenance
2. update your DNS or /etc/hosts settings to reflect new engine IP
3. change engine network configuration to reflect new IP. restart
networking. (not need to reboot engine)
4. at engine: systemctl restart ovirt-engine, systemctl restart
ovirt-imageio-proxy.service (might not be needed)
5. disable global maintenance
6. login at GUI using the same engine fqdn.
Afterwards I confirmed that imageIO proxy and OVN was ok by testing their
connection through GUI, confirming that there is no certificate or other
issue. Also observed for a while engine logs about any error and found
none.
Hope this helps.
