Changing subnet on site in Active Directory

A new building is being built were I work. I have one Domain and several Sites within MyDomain. At the site (A) where the new building is being built a 10MB fiber connection to our ISP has been installed and the subnet of this new building will be 10.228.X.X. What I am trying to figure out is the best way to role everything over from the old building, which is site (A) and has a subnet of 10.223.X.X to the new building which has a subnet of 10.228.X.X. Is it as simple as changing the subnet mask for the site (A) in Active Directory Sites and Services, and changing the ip on the Windows Server 2003 Domain Controller to match the new subnet. Or is this not a good idea. What is the best thing for me to do?

Hi
And remember to decrease the lease from your DHCP scope. That will increase a little the trafic on DHCP but when the wsk will be decrease the time needed for wks to change the DHCP server.

Can I add the 10.228.X.X subnet to site (A), and still keep the 10.223.X.X. I want to add another domain controller to the site, but the server is installed in the 10.228.X.X subnet. Can site (A) have 2 subnet's defined to it, 10.223.X.X and 10.228.X.X. I want to keep the old building up and running until everyone is moved out of it, and then I will pull my first domain controller for the site into the new building and change it's ip and etc. Will that work?

You can have 2 subnets for one site. but be carefoull what servers is in that subnet, or else you will have some sloww network access.

Can I have a Domain Controller providing DNS and DHCP to the 10.228 subnet, and another Domain Controller providing DHCP and DNS for the 10.223 subnet?

Yes but the clients will be in unprecised site. You cant say what DHCP server will provide first the service to one client. Except for the clients that have an lease already. This one will stay on old DHCP until is removed.
