I'm new at this company and I've been doing a lot of maintenance and clean-up that hasn't been done in a long time. On their Exchange 2010 server there are two databases, one contains most of the mailboxes and the other "exec data" looks like it contains a lot of the most recently added mailboxes, but I don't see a reason to separate them in another database.
I ran a local move request to move all the mailboxes on to the main database. Once this is done, is it save to dismount and delete the empty database? Any considerations I should be aware of?
