You could read the UPGRADING document in the source distribution.

To upgrade any 2.1.5+ release to  the latest release is very
straightforward except 2.1.18+ requires that you have the Python
dnspython package. This is discussed in the "UPGRADING FROM 2.1.5+ to
2.1.18+" section of the UPGRADING document.

When 'make install' detects a version change, it runs
Mailman/versions.py which does any necessary conversions.

Just do it. Unpack the current Mailman 2.1.26 release (or wait for
2.1.27 which is coming soon, or grab the branch from
<https://code.launchpad.net/~mailman-coders/mailman/2.1> which is what's
running on the @python.org lists), run 'configure' with the same options
as you used on the current install and then 'make install'.

Also note that every time a list is instantiated, its data_version is
checked against that of the installation and if it is older, it is
automatically upgraded.
