Are you planning to install on a new host/VM?

You have basically two alternatives:
A. backup the DB and restore it on the new engine as described here:
http://www.ovirt.org/Ovirt-engine-backup

B. Start from scratch with a new engine on a new DB and re-import existing storage domains:

Option B involves a lot of manual steps but it could be also used as a disaster recovery flow when the DB is for any reasons lost or corrupted.
