[Mailman-Users] Changing servers and upgrading at the same time

I looked through the archives and didn't find anyone posing the same or similar question, so....

I'm currently running Mailman v1.1 on a Redhat 5.2 system.

I'm building a replacement server with RedHat 7.0, and am curious what is the easiest and reliable way to switch the mailing list(s) to the new server, while upgrading to Mailman 2.0.1.

Do I:

(1) Install Mailman 2.0.1 on the new server and somehow copy the subscription info and archives to the new server?

(2) Copy the existing Mailman 1.1 installation to the new server and then upgrade it to 2.0.1?

(3) Some other alternative?

Suggestions are welcome.
