[Mailman-Users] How to move lists/subscribers to new machine?

[Peter]

I have an old installation (2.1.5) that I want to move to a new machine 
(running 2.1.8).  I was wondering how to go about moving the lists and 
subscribers over.  After that I will worry about the archives.

The first machine is running Mandrake Linux and the new machine is running 
OpenBSD 4.0.

Thanks to any responders,

Pedro
