Exchange 2003 Public Folders -- Need a script to add replication Server

I currently have Public Folders on an Exchange 2003 Server.  We are migrating to Exchange 2007 server.  I need to add my 2007 server as a replication Server on each Public Folder.  We have over 1700 Public Folders on the network. 

Is there a script i can run to get this to be added to them automatically OR will I have to manually touch each folder?

I know I need to get this replication turned on and going before I copy Replica to the new server.

Any help would be appreciated.
