Good afternoon. We currently have 3 older Dell floor unit servers running Windows Server 2008 R2. All of them have the exact same server roles (AD, File Server, DHCP and DNS). This year we bought 3 brand new Dell rack mount servers we would like to use to replace these older ones. The new servers are running Windows Server 2012 R2. I want the new servers to have the exact same name and IP address as the old servers when its all said and done. I'm looking for an article or some pointers on how to approach this. Here is what I was thinking:
-Copy files for File Server role from 2008 server to 2012 server using something like robocopy (or any other utility someone may suggest)
-Demote current 2008 AD server and reboot
-Rename demoted 2008 AD server and change the IP address and then reboot
-Rename the new 2012 AD server and change the IP to match the old server and reboot
-Promote new 2012 AD server as new DC
Does anyone see anything wrong with this or have any input on what I should do? Any help is appreciated. Thanks
