Hi All.
I recently starting work with a company that has gone through multiple sysadmins.  I am in the process of cleaning up their network.   Currently,  I am researching replacing the two AD Controllers (DC1 is a 2003 AD Controller,  DC2 is a 2008 AD controller.  DC1  is also the primary DNS and DCHP server.   I would like to retire these server and replace them with 2012 servers.  I would like to keep the IP addresses the same as the current DC1 and DC2 servers, so I don't have to go to each workstation and change the static IP to reflect new DNS servers.    I would Like to confirm the roles of the existing servers and make sure they are functioning correctly and move the roles to the new servers.   I would also to move DHCP to the new DC2 controller.
Any suggestions, links,  horror stories, etc?

The rough steps will be as follows...

1. Setup the 2012 servers.
2. Join them to the existing domain using unassigned static IP addresses.
3. Install AD support (add/remove features) and promote them to additional DCs.
4. Dcpromo will configure DNS for you. DHCP will have to be added manually to DC2.
5. Transfer FSMO roles to new DC1 (global catalog DC)
6. After hours, enable DHCP scope on DC2. demote old DCs then shut down, taking note of current IP settings. Change IP settings on new DCs to match old DCs.
7. Raise Domain Functional Level to 2012.

I can provide details as you execute each step if you run into issues or have doubts about continuing. Good luck!
