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:

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.

Do I understand you correctly that you're suggesting I install the OS onto a new VM, and try to do a restore of the oVirt settings onto the new VM (after I put the cluster into Global maintenance mode and shutdown the old oVirt)?

Hello David,
                      I don't think there's a documentated method to go from a Hosted Engine to standalone just the other way standalone to HE.

I would suggest doing a full backup of the engine prepare the new VM and restore to that rather than trying to export it.
This way you can shut down the original engine and run the new engine VM to test it works as you will be able to restart the original engine if it doesn't work.

In other words, I want to migrate the Engine from a hyperconverged environment into a stand-alone setup.

Hello,
I have just purchased a Synology SA3400 which I plan to use for my oVirt storage domain(s) going forward. I'm currently using Gluster storage in a hyperconverged environment.

My goal now is to:
  • Use the Synology Virtual Machine manager to host the oVirt Engine on the Synology
  • Setup NFS storage on the Synology as the storage domain for all VMs in our environment
  • Migrate all VM storage onto the new NFS domain
  • Get rid of Gluster

My first step is to migrate the oVirt Engine off of Gluster storage / off the Hyperconverged hosts into the Synology Virtual Machine manager. 

Is it possible to migrate the existing oVirt Engine (put the cluster into Global Maintenance Mode, shutdown oVirt, export to VDI or something, and then import into Synology's virtualization)? Or would it be better for me to install a completely new Engine, and then somehow migrate all of the VMs from the old engine into the new engine?

Thanks,
David
