It is /var/mailman/lists/<listname>/config.pck if the old version is
2.1.x or /var/mailman/lists/<listname>/config.db if older.

If it is config.pck, just replace the config.pck for the newly created
list with the one from the backup. This should restore subscribers,
list configuration, subscriber options, etc. from the old list

If the old file is a config.db, you would need to restore the old
config.db to the new lists/<listname>/ directory and also remove any
existing config.pck and config.pck.last files from that directory.
Mailman should then be able to update the list configuration and store
it as a pickle in config.pck, but there may be problems with this due
to (as I understand it) the format of a Python marshal (the config.db
file) not being constant across Python versions. I.e. Mailman will be
able to convert it iff the Python on the new system can read it.
