I have a single Exchange server environment.The server I had Exchange 2003 installed (ofm7) on began to fail, so I installed Exchange 2010 on a regular workstation (called it OFM8) and migrated all of my mailboxes and public folder over to it, then rebuilt the faulty server (OFM7). I have the OFM7 up and running now with Exchange 2010 and Server 2008 R2 all the mailboxes and public folders installed on it. I can reconfigure my mobile devices to point to OFM7 and everything works. Now I need to have the MX record point to my OFM7 server remove the server OFM8.
My question is what is the step by step procedure from this point forward? Do I just repoint the MX record and remove OFM8 from AD? I suspect there is more to it than that.
