I am afraid that you cannot change the address of the management
network while the host is attached to Engine. The reason is that
Engine always uses this address to communicate with the host.
You could change it only if you remove the host from Engine, modify
the address manually, and re-add the host using the new address.

AFAIK if you use a DNS name of the host when you add it to an engine, then
its IP could be changed as long as that name continue be resolved to the
host new address.

Yes, but then that DNS becomes a very bad SPOF for your system, so not
a good idea for a production systems...

Hello,
I was able to get this sorted out by editing the IP=92s in the database. Af=
ter I edited them so the engine could reconnect to the servers, I simply re=
moved them one by one and re-added them to the engine dashboard. So far, th=
ey are working as expected.
psql engine -c "update vds_static update host_name =3D 'newIP' where gatewa=
y =3D 'oldIP';"
After, it complains about the networks being out of sync which is OK. Simpl=
y reinstall the host =96 I had to remove them one by one first, add them ba=
ck, then I was able to resync the networks without issue.
Should this be used, always make a backup of the engine first.
