The upgrade command lets you upgrade earlier lists to your current

You need to backup your current install of Mailman 2.0.13 then install
the latest version of 2.1. If you install over your current install (as
opposed to installing in some other root location), your lists will be
upgraded automagically, and some of the default settings will not be
especially to your liking.  

Most folks do not read the upgrade document that comes with 2.1 and
consequently have many problems - all of which are avoided by reading
the upgrade doc.

You will need flush your queues before upgrading.  Also, you will need
to kill the cron commands so that qrunner is stopped from launching
every minute.

After the upgrade, you will need to make sure that you are using the new
crontab settings for mailman (which no longer have a qrunner being
kicked off via cron). You should edit the mm_cfg.py file after reviewing
the Defaults.py file, and setup your new defaults. There are some very
different things in 2.1 so this is a very important step!

Next create a group called "mailman" which you should subscribe to
(become a list member, and restrict membership to this list), as all the
errors, warnings, and bounces go here. Then you will have to start the
Mailman service (mailmanctl). If you haven't created the "mailman" list,
mailmanctl will NOT start.

If you did a parallel install, you can now simply copy the old lists
subdirectories over to the new ~mailman/lists/ directory (and don't
forget about the archives!).  On the fist access of each list, Mailman
will automagically upgrade them.

That covers the highlights. If you do the upgrade by the numbers, then
all will go well and you will be done very fast!

Good Luck - Jon Carnes
