Adding Exchange 2003 PF Replicas to every Exchange 2010 server

Hi,
We had PFDAVadmin tool to set up our public and system folders and Exchange ’10 server prior to upgrade into SP1. At present we got two other servers of mailbox and we need the prior things in our settings. The PFDAVadmin is not giving me access to select the servers by name rather that the group of admin can be selected. Having different store domain names I am only able to select one not more than that as they are under the same name. Is it happening for the SP1? How would it be possible to have the ’03 PF replicate on the ’10 servers? Thank you for your help on this one.
