I thought I'd report back to the list and mention that I was successful in migrating
off of the hyperconverged environment onto a stand-alone engine environment, and Gluster
has been removed from the oVirt configuration.
I ran into a few minor hiccups, all of which were resolved fairly easily, and I took
notes. I intend to submit a PR to the github documentation, since none currently exist for
migrating the engine off of a hyperconverged environment.
My only remaining questions at this point is:
- Are there things on the hosts themselves that I should cleanup? I noticed that the
"hosted-engine" command still exists. I went to run a `yum remove` on that, and
it tried to remove basically everything... so I figured that wasn't actually a good
idea.
- Do I need to do anything in the oVirt config (maybe something in the Postgres
database) to basically tell it that it is no longer self-hosted, but is instead
stand-alone?

Hi Paul,
Thanks for the response.
I think you're suggesting that I take a hybrid approach, and do a
restore of the current Engine onto the new VM. I hadn't thought about this option.
Essentially what I was considering was either:
- Export to OVA or something
OR
- Build a completely new oVirt engine with a completely new domain, etc... and try to
live migrate the VMs from the old engine to the new engine.

into Global maintenance mode and shutdown the old oVirt)?
