Of course, I would be remiss to point out that we DO NOT test this feature _at_all_ and that you should have a good, tested backup on hand, just in case. Personally, I would also (take the performance hit) and make a snapshot just to add a belt to my suspenders. I would remove the snapshot when I was happy enough with the result. b.
