I have an organization with 130 users, 1 server 2003 that function as DC And files server and 1 server 2003 with Exchange 2003.
I intend to buy 2 new servers . one 2008 server for DC and Files and the other one for Exchange 2010. after the migration i want to use one of my old servers as second DC . (to rebuild him with server 2008 OS).
What is the best way for this migration process ?
