Hello All,My Exchange 2003 Standard store is on a disk which is now too small for the store, and so I want to put it on a larger disk. The way I intend to do this is as follows: Stop the Exchange services, Backup the entire disk to tape using NTBACKUP, Delete the existing volume on my RAID array Recreate the volume, but with a much larger capacity (retaining the same volume letter), Restore the backupto the bigger disk, Restart ExchangeAm I being incredibly naive here, or should this just work? Have I missed anything? Do I need to run any processes after restarting Exchange?Any help (or even just reassurance) that anyone could give me would be greatly appreciated.My thanks in advance,Paul

Hi Paul,I think it is a good idea to add couple of below steps.~ Before stopping Exchange services make sure that you have selected"Don't mount this store at start-up" in the properties of Mailbox and Public folder database. So by mistake if services are come up, Exchange databases don't mount.~ After stopping Exchange services and before taking backup run eseutil /mhDatabase_File_Name to make sure that databases are in Clean Shutdown state.Untick the option don't mount this store at start-up after finishing the full operation.Amit Tank | MVP - Exchange | MCITP:EMA MCSA:M | http://ExchangeShare.WordPress.com
