I have a new SBS 2008 computer that I am using to replace (2) Server 2003 servers in our small company (neither of them actually has SBS installed on them).
As far as I can tell, both 2003 servers are domain controllers.
One of them is running Exchange which we are using for email.
Shared files and folders span both servers (I think the second one was added to give them more file space).
I need to run the AD migration prep tool on my SBS2008 DVD on one of the 2003 servers.
Do I just run the tool on one of the 2003 servers, or do I need to do it on both? What issues do I need to be aware of here?
