public to private IP migration question

I have an Windows 2003 network spread over 2 public IP subnets. I need to
move to a private (DHCP) IP network. If I add Private IP (192.168.0.x) to
the network cards on the domain controllers and other servers in ADDITION to
the current public address currently used, and create a DHCP server to
handout private 192.168.0.x address will I be able to run both public and
private networks concurrently while I migrate?
Or do I need to reconfigure each server and client at the same time (over a
weekend) to make this work?

If I were you, I'd definitely do this in one fell swoop over a weekend. You
also need to change DNS, WINS, in addition to DHCP...as well as statics/DHCP
reservations, etc.

Yes

No. Systems will reach other systems in the same logical network.
You need a router if you have some only in the new IP range and others
only in the old one for the two to see each other.

Just do it over the week end and be done with it. There's no point in
fighting with a multi-net. You'll end up spending more time wrestling with
that then you would to just convert it in one shot over the weekend.
