I have 2 win2003 domain controllers (let's call them DC1 and DC2). Both of them are our DNS and DHCP servers. Since both of them are very old (more than 8 years old), I want to replace them with win2008 (call them DC3 and DC4). More than 50% of our workstations are using static IP with static DNS servers info. I want to keep administrative tasks to the minimum. So by the end of this project, I want DC3 and DC4 to have IP of DC1 and DC2.

Here's my plan: promote DC3 to domain controller > demote DC2 and take it offline> assign DC2's IP to DC3 > promote DC4 to domain controller > demote DC1 and take it offline > assign DC1's IP to DC4

It sounds simple but you'll never know what you get yourself into when it comes to domain controller.

couple questions:
- Is it a good plan?
- or is there a better way to handle it?
- or should I keep it simple like this: give DC3 and DC4 new IP > change DNS servers on all workstations that use static IP?
- anything I should be aware of when new domain controllers use same IP as old domain controllers?
- should I go with win2008 or win2008 R2? we have about 300 clients (workstations + servers)

Thanks in advance!!
