After you installed a new DC and they are replicating perfect with SBS then you need to do the following:

1. Move the Data, printers and shares
2. Change the port forwarding in the FW.
3. Change the DNS and DHCP to point to the new domain
4. Remove Exchange 2007
5. Remove the CA role.

7. Dcpromo the server and if there is an error to remove the delegation record from the DNS, don't worry this will not stop the dcpromo.
8. After the server restarted, clean the DNS and Site from the SBS.
