samba - May 2006 - 2 PDC's on same Network

Hi,

I'm looking to replace our existing Samba 2.X.X PDC with version  3.0.20.  I
would like to configure and test the new PDC with our existing ldap server on
our network.  Is it possible to have two working PDC's running on the same
network at the same time.  Will the new PDC cause any problems with the existing
PDC and user logins?
