I have two windows 2003 domain controllers that I am decommissioning. Last week I brought up two 2008 R2 domain controllers and transferred all the FSMO roles. Right now the DNS settings on all workstations and Servers on the network is pointed to the 2003 Domain Controllers that I am going to decommission. So of course when I shut down the 2003 DC's things are not going to work properly because everyones DNS is still pointed to these Servers. Is it possible to give my Windows 2008 Servers a secondary IP address of the 2003 DC's that I am shutting down? This way everyone won't have to change DNS Settings. Thanks.
