First attempt at Replacing a DC

We are getting a new server Windows 2003 Enterprise(r2)that is going to replace our old server. Currently we have a Single Forest Single Domain running Windows 2000 Small Business Server. I am just hoping to get a confirmation/insight on the promote and demoting process of the DC. I am going to add the new server to the forrest and using that new server to replace the old server, NOTE **this is all happening on the same network**
I think the process is,
– Run dcpromo on the new server, for the controller type additional domain conroller for an existing domain.
– Then I have to assign static ip addresses to both servers.
– then i dcpromo the new server and dcdemote the other server
– mission accomplished?
