Hi Didi, thank you very much for the quick response. A small report from my side: After doing your instructions I get some error messages from engine-backup. I have to remove the folders /var/lib/ovirt-engine-reports, /var/lib/ovirt-engine-dwh, /etc/ovirt-engine-reports and /etc/ovirt-engine-dwh manually. Then engine-backup works again. Otherwise nothing has struck me.

Thanks for the report! I'll update the wiki page about migration. Best,

Best Regards, Michael

Hi all, how can I safely remove the DWH extension in ovirt 3.5.1?

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;

...

Is there a howto?

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.
