Moving from Exchange 2003 directly to Exchange 2013!
Posted on 2013-01-30
I know there is no direct migration path between Exchange 2003 to 2013, and I just bit the bullet and purchased a new 2012 server and Exchange server 2013 with CALS. I was planning on simply exporting all 15 user's mailboxes via Outlook 2010 to pst files. Also exporting several public folders (not many 4 mail and calendar folders in total).
I understand I will first need to remove Exchange 2003 from the 2003 Active Directory domain. Once Exchange 2003 is removed from AD I can then go ahead and install Exchange 2013.
I forgot to mention I also purchased another server as well that will be our new 2012 DC. I was planning on joining this server to the existing domain and having it replicate.
Anyway, I am just wondering if all that is needed is to remove Exchange 2003 is going thru add/remove programs on the server. I am hoping it will allow me to remove it as well. Also I know I need to disconnected each user to their respective mailbox beforehand. I am hoping doing so will completely remove Exchange 2003 from AD.
I was thinking of saving the Outlook client steaming file for each user so their autocomplete entries will remain intact. Am I looking at any other complications that I am not aware of? What I mean are problems installing Exchange 2013 and also once I get it installed and everyone's mail in their mailbox will they have problems responding to previous emails, etc?
