I'm attempting to move a 110GB Exchange database off of a old machine (see below for specs) to a newer machine ( see below for specs). I've successfully linked the new machine to the old machine's domain, promoted it to a domain controller, and have Active Directory synced perfectly.

What is the proper way to go about this? I followed Microsoft documentation on it to no success.


Old: Windows Server 2008 R2 Standard SP1 Intel Core 2 Quad Q8400 (yuck) 8GB RAM 1 1TB HDD

New: Windowss Servers 2008 R2 Standard SP1 Intel Xeon E3-1240 V2 16 GB 2 1TB HDDs

    woah woah woah what? You've promoted the new server to a domain controller before installing exchange on it? – tombull89 Jun 24 '14 at 8:39
  • Should of included that. I installed Exchange BEFORE promoting it. I can access all the mailboxes from the new machine and users can send/receive mail from the new machine as long as the old one is kept on, which is correct I'm assuming since they are on the same domain. – Jordan Jun 24 '14 at 8:40

    Professional version: Get real and do not run exchange on a domain controller. Seriously. – TomTom Jun 24 '14 at 8:46
  • That's the end goal is to get the exchange server off the Domain Controller. – Jordan Jun 24 '14 at 8:50

    There is pretty much never a good reason to do something like that. DCs should only be DCs, and have only directory things on them. You might want to start over, assuming that won't result in data loss - your question is terribly vague. – Falcon Momot Jun 24 '14 at 9:11

You create a new Database and then Move the mailboxes over. In EMC, right click mailboxes and choose "New Local Move Request", then work the wizard.

Or use EMS and use e.g.:

Get-Recipient | where {$_.ServerName -eq "<servername>"} | New-MoveRequest -TargetDatabase <targetdbname>

after moving all mailboxes, you can start decommissioning the old server.
