They are the list configuration and membership (config.pck)
the 'backup' list configuration and membership (config.pck.last)
The list's pending confirmations (pending.pck)
The lists moderator requests (request.pck)
The var/lib/mailman/lists/* tree is what needs to be moved in order to
move lists from one server to another.
Also you need to move the heldmsg*.pck (or heldmsg*.txt if you set
HOLD_MESSAGES_AS_PICKLES = No) that are in mailman's data/ directory
(/var/lib/mailman/data/ ?) and the archives in
These steps or variants thereof are outlined in the list posts

I meant were their timestamps recent or old, but now that we know what
files you're talking about, that question isn't relevant.

It is safe to move them to a more recent Mailman version and mailman
will update them as needed for the new version as they are accessed.
It may be a problem to move them to an older Mailman version, but that
is not the case here.
A different Python version should not be a problem as long as Mailman
runs on the new installation.
