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?
