We just got a new Dell server with 2008r2 to replace our old HP Sever 2000. Our network has about 40 users. I am ready to start the migration process. The HP is our only server and runs active directory as well as file, print, dchp, and dns server. I will be transferring all of those roles to the new server. We use MDaemon email server which is on a workstation that will eventually be transferred to the new server, but there is no Exchange. I've read a few things on the migration, but have a few questions.
I am hoping to be able to perform the DHCP, Active directory, DNS and promoting the new server to a DC steps during the day while users are accessing the network. Is this OK to do? I will be doing the file transfers during off hours.
Are there any special considerations or recommended walk through for the steps I'm about to take?
I've been administering the 2000 server for about 5 years, but this will be my 1st migration so any help would be very appreciated.
