Is there a way to change the Engine History from Advanced to Basic ?
Yes, run 'engine-setup --reconfigure-dwh-scale'.
You can also manually change  to whatever specific values you want.
I don't see this documented on the ovirt site, you can use RHV docs.
If so I also would like to know how to empty the DB for older data
when it's on Basic again, manually.
I don't think we have this documented. It's similar to  though.
We have  open to do this properly one day.
You can try something like this:
1. Stop dwhd
2. rm /etc/ovirt-engine-dwh/ovirt-engine-dwhd.conf.d/10-setup*.conf
3. Connect with psql as user postgres and then:
drop database ovirt_engine_history
drop user ovirt_engine_history
I didn't try this myself.
