Can I do this to Exchange?

Is there anything wrong with this? Lets say I wanted to move an exchange database to a new computer. The computer has exchange setup on it, but it’s not doing anything.

Can I unmount the mailbox store under the first storage group, and remove the default EBD and STM files- and then copy the ones I want to use there and re-mount the store?

I tried this on my text box. It seemed to work fine.

I am thinking of ways to perform the fastest recovery possible (in case I ever have to) as my production environment is not fancy: no redundant server, no backup server- just a SBS server with a tape backup.
