The problem with "cloning" is that when you make a copy of the database, it still points to the original CMS server. So, when you first bring the new CMS up, it thinks it is in a cluster with the original server and very strange things can happen.
For example, our production staging environment has an exact copy of the production databases that is made every time we do a software release to production. The first time we did this after we BObj running in production, I ran into some major problems when I brought the prod staging CMS up. I changed the CMS properties to point to the correct database, but that database said it was part of the production cluster. So I renamed the "cluster" in the CMS properties to point it back to the prod staging server. At that point, no one could log into production because it had changed the name of the production cluster in the production database even though the prod staging CMS should have been reading the prod staging database! I suspect that if the production cluster had been down, I wouldn't have had the problem. However, we now export the prod staging CMS database prior to the db copy and then truncate the tables to remove the production data and add the correct data back to it before we ever bring prod staging back up.
So, I would be very wary of just cloning the database! If you're moving from one server to another, I've outlined the steps here: thread782-1361382.
