I am preparing to change my two site network which is currently set up as a parent and child domain to one domain (the parent). Currently the DCs are set up as Domain1.local and Domain2.Domain1.local. The parent domain is running Server 2008 R2 and the child domain is running Server 2003. I only have 25 users on the child domain and had thought about just setting up the new Server 2008 R2 server and recreating the users as opposed to collapsing the child on the older server. I was hoping to install the new server at the remote location and bring the users over one at a time as to avoid downtime. I have staged the new server at the parent site and am creating the new remote users. The scope at the main domain is 192.168.1.X and 192.168.5.x at the remote location. Do I need to create a new scope at the remote location to add this new server? Am I approaching this project correctly? Advice anyone? Thank you.
