WE have some apps in the environment that are hard coded to use IP of old 2003 Domain Controllers that we are replacing with 2012 Domain Controller. WE need a plan to reuse current IP for 2003 DC for 2012 new DC. I know you cant have the duplicate IP address. WHat are the steps we need to do in order to re-use the old IP of 2003 DC for 2012 Dc?
Please let me know.
