moving plr mailing lists

Howdy folks,

Joe is hoping to regenerate the archives from his old mailing list 
http://gborg.postgresql.org/mailman/listinfo/plr-general
into his new mailing list at 
http://pgfoundry.org/mailman/listinfo/plr-general.  One potential issue is 
that he has had traffic on both lists, and some of it overlaps (date wise).  
Can we still regenerate his archives, or will that wipe out the new posts on 
the new list?
