I'm building a new BackOffice Small Business Server 4.5 to replace my current one. I have the SBS software on the new machine but It cannot be promoted to the PDC (Primary Domain Controller) and the Exchange Server portion will not install due to the existance of the existing SBS (I believe).

Do I just need to down the existing SBS to promote the new one to the PDC? And then never bring the existing one up?

What is the best course of action to migrate my Exchange Server Data to the new SBS???

The two SBS PDCs cannot coexist. I recommend you follow the instructions found in Q228980 "Upgrading from SBS 4.0 to SBS 4.5 When Migrating from One Computer to Another". Obviously you're not upgrading, but the data transfer concepts remain the same. You can access this document by visiting www.microsoft.com/technet and searching for Q228980.
