[Mailman-Users] Migrate from Lyris to Mailman

[Stephen Cook]

Hi,
I've been asked to migrate the mailing lists from Lyris Listmanager running on Windows 2003 to Mailman on Red Hat Enterprise.  My director would like the migration to go in such a way that none of the mailing list users would be required to change the entries in their address books.  To complicate matters further, the old server hosts web pages as well.  So requests to "http://oldserver.mydomain.com" should go the the old Windows server, and "mylist at oldserver.mydomain.com" should go to the new server.  I've been banging my head on this problem for the last couple of days.  My questions to the mailman community are 1) is this possible/feasible and 2) If so, what's the best way to do this.

I've figured out how to pull a test file conting the lists & list members from Lyris.  I've also figured out how to forward email address to whatever at oldserver.mydomain.com to the new server.  

Thanks,
SC
