I have a site that currently has a 2003 SBS with no exchange installed it's only acts as a DC. I'm wanting to setup a trust between both sites and with the SBS 2003 this is not possible as we all know. What I would like to do is build a new server 2008 server DC / run dcpromo transfer the FSMO Roles to the new DC then dcpromo the SBS 2003. Then cleanup DNS .. Will this work?
