Currently running Exchange 2003 SP2 Ent. The edb file is 200gigs and the stm file is 150gigs and am about to run out of space on the E: drive that is holding the database store. I’ve recently added another logical drive and would like to separate the edb and stm files. Is there anything to concerned about in unmounting the store, moving the stm file to the newly created drive, change where Exchange is pointing to the stm file in System Manager, and then remounting the store. This seems like it should work but any advice/insight/concerns would be appreciated.
