----- Original Message ----- This depends on how "safely" you want this... Just stopping the services and removing the packages should be enough. I didn't verify what happens if you e.g. later try to run 'engine-cleanup' (How will it react when trying to remove them?) or re-install (will they behave as if already setup?) etc. You can/might then also remove the databases from postgres, e.g. # su - postgres psql drop database ovirt_engine_history; drop database ovirt_engine_reports; Not for this per-se, but [1] shows how to migrate them to another machine. We also have open bugs [2][3] to do this more cleanly, but they'll require some more work, and it currently does not seem they'll make it to 3.6.
