In your case, I'd recommend starting with just the site list on the new
system and then copying the lists/ and archives/ directories.

The new Mailman will automatically translate the old format files in
lists/ as they are used.

There may be a problem with pending requests (held messages, pending
subscriptions, etc.) if any. I'm not sure where these are in 2.0.13.
In 2.1.5, they moved from a global data/pending.pck file to individual
lists/listname/pending.pck files. If you upgraded a 2.0.13
installation to 2.1.6, the upgrade would take care of it, but I don't
know how you can 'move' this information from 2.0.13 to an already
installed 2.1.6. It would be best to deal with as many of these as
possible before the actual move.

And "testing the hell out of everything before" switching is definitely
the way to go.
