I have a two site single SBS domain network I want to break into two separate networks. Here is a brief description of the current setup.
Site A (Primary Site)
SBS2003 (FSMO holder, GC)
AD, DNS, DHCP, GC
Connected by site-to-site VPN
My goal is to get both sites operating independently and remove the VPN. I'm already aware of all the licensing I need to achieve this. I'm looking for some advice on the separation. Here is my initial plan.
perform swing migration from SBS 2003 to Win 2012 R2.
This is where I'm unsure on how to proceed. Can I run a swing to 2012 R2 then use the domain rename tool to rename my internal domain at site B to something more appropriate to the organization and different than site A? Or does that even matter? I do have several users that work primarily at Site A but occasionally travel to Site B to work. What ramifications, if any, exist by just renaming the domain for these users?
Of course I can always start from scratch and build a new internal domain and migrate existing users to it but that is much more labor intensive and disruptive.
I look forward to the feedback. Thanks in advance.
