Do not manully create the old lists on the new server. This is
Copy/backup the lists/<listname>/config.db files from the old machine
and copy/restore them to the new server. There must not be an existing
lists/<listname>/config.pck on the new server at this step. If there
is because you created the list on the new server, remove the
config.pck leaving only the config.db.
Archives can be moved by either moving the entire archives/private/
tree or by moving just the
archives/private/<listname>.mbox/<listname>.mbox file and running
'bin/arch --wipe <listname>' for each list. If you do the latter, it
is a good idea to first check the .mbox files with bin/cleanarch.
Mailman will automatically update the config.db info (list config,
membership, options, etc.) and save a current format config.pck as
each list is accessed. You can force this for all lists by just
running bin/list_lists. Once the lists are converted and there are
config.pck and config.pck.last files, remove the old config.db or you
run the risk at some future time of falling back to the config.db if
the config.pck* files become corrupted.
