I believe I've done this already in the past but doesn't hurt to run it by the experts.
Want to make sure changing the IP scheme on a network (including the DC) doesn't hurt the DC.
we're changing from a 192.168.1.xxx  to a 10.7.1.xxx    
anything in particular to watch out for on the DC prior to changing the IPs?

1) Update/change your DHCP scope to meet the IP schema.
2) Update all static devices to match
3) Update/change DNS Pointer records
4) Update router and port forwards

Make sure your DNS and DHCP servers are ok

Have a RRAS server check those ip address also.

How many DC's you have

More than one change them first.

Where is DHCP handled?

Where is DNS?

Currently, DHCP is disabled.  DNS is on the windows 2003 server (2 DC's onsite).

Slight change of plans since we didn't want to go around and update everyone's Static IP.  During the migration, I'm going to create new DHCP scopes with the various VLAN's and their IP's.   on the day of the migration, i'll turn the scopes on so the pc's can pick up on the ip (after changing the static properties to DYnamic).   Then go back and reserve the IP's once they obtain one.
