When is it best to switch IP addresses during/following a Migration to a Windows 2008 Domain?
I'm preparing for a migration of my windows 2000 domain (native mode) to Windows 2008 R2. The current 2000 domain contains two windows 2000 DCs and two 2003 DCs. I'm planning on using the new 2008 DCs as DNS servers too. In addition, I would like to reuse the IP addresses from the old DCs on the new ones so that I won't have to reconfigure every device and client on the domain. At what time or stage is it best to switch the IP addresses from the old DCs (old DNS servers) to new DCs (new DNS servers)?

I would switch the IP addresses to the new DCs after you have finished all setup, configuration, and patching of the new DCs. That is the least disruptive.

Hi Kevinhsieh, thanks for your prompt reply. So you are implying that the DNS on the new DCs shouldn't be setup until very late in the process since they are also going be DNS server and will be using the same IP address as the old ones?

So what both of you are essentially saying is that I can setup DNS and DHCP on the new DCs but not activate until the IP addresses are swapped from the old DCs to the new DCs and viceversa, correct?
However, for DHCP I'm planning on using the same DHCP scope does the IP swap rule out importing the DHCP scope from the old DC.
