[Mailman-Developers] Transferring lists

I'm in the process of transferring lists to a new server. The old server runs mailman 2.1.4, and the new one runs 2.1.5. I copied over the lists directory and the archives directory, and I ran update -f to update the lists. It seems to be working except for the fact that now the lists don't show up on the main listinfo page. Before they were listed publicly. How can I get this back? And is there anything else I'm missing in this process of moving lists?

Thanks, Joel Ebel
