Changing IP Addres / Subnet for the AD Servers

Hello Guys,

We are looking to collapse a remote Data Center back into the main and
I wanted to get the recommendations on the best way to go about this. For
ease of explanation I call the remote location , location X , and the main
center we are collapsing into, location A.

Location X currently hosts its own AD/WINS/DNS, Print, App, ISA, and
Exchange Servers. They are running on a 10.5 subnet and connect to location A
via Gig Fiber. Location A is currently running on the 10.20 network.

What would be the recommended route to move the Servers over to
location A ( 10.20.X.X Network ) from location X ( 10.5.X.X Network) ? Is it
as easy as change the IP Settings on the NIC for the AD Servers, host record
in DNS, and pointing the clients to the AD/DNS Server that has the new IP in
the clients DNS Server entry ? Both the AD Servers are the DNS Servers for
the Domain , so I assume if I change the IP Settings( IP Address, Mask,
Gateway) on the Servers Nic, change the DNS Host Entry for that Server on
that server, point all the clients to the new DNS Servers via their DNS
Server IP address for the clients Network Config, the clients should be able
to access the server on the new subnet ? Would changing the IP Address on
the AD Servers mess anything up in AD, DNS, Wins ?

Also, What would be the recommended route for the Exchange 2003 Server ?

Why change the IP addresses at all? What is wrong with having the existing
remote site running in its own subnet?

If you move them so that they are all at the same site, what is wrong
with simply replacing the WAN link with a LAN router?
