<div dir="ltr"><div>All,</div><div><br></div><div>Over the past years (as early as
2014, I think), there have been many times we've seen the need to move
off Mailman2: it's implemented in python2.7 which has long seen the end
of its life.</div><div><br></div><div>The alternative has always been
Mailman3, which is the technological successor of Mailman3, but a
complete rewrite. As early as its initial release in 2015, I've been
eyeballing moving to it.</div><div>Back then, there was no migration
path from 2 to 3, but it was on the roadmap, which made the choice to
move or stay easy: wait for the release which makes it possible.</div><div><br></div><div>A
lot of time has gone by since. The situation gradually worsened,
because the migration to Mailman3 became a blocker to upgrade the
operating system on <a href="http://common-lisp.net" target="_blank">common-lisp.net</a>:
python2.7 was phased out, which means the mailman2 list software
wouldn't run on it anymore (that is, without significant maintenance
burden to maintain our own python2.7 install).<br></div><div><br></div><div>Long
story short: Yesterday, I installed the containers which allow us to
run mailman3 in an isolated environment. There's a lot of tweaking to be
done, but I've been able to configure mailman3 to run alongside of
mailman2, which is a good start.</div><div><br></div><div>As of right now, I've started migrating to mailman3, which I'm doing in steps:</div><div><br></div><div>- basic validations<br></div><div>- archives of defunct lists</div><div>- active mailman2 lists with configuration and archives</div><div><br></div><div>Before
going the route of migrating active lists, I may do an assessment of
the activity of mailing lists, asking owners of mailing lists which have
gone without activity for 5 years, whether there's still an active
interest.</div><div><br></div><div>Regards,<font color="#888888"><font color="#888888"><br></font></font></div><font color="#888888"><br clear="all"></font><br clear="all"><br><span class="gmail_signature_prefix">-- </span><br><div dir="ltr" class="gmail_signature" data-smartmail="gmail_signature"><div dir="ltr">Bye,<div><br></div><div>Erik.</div><div><br></div><div><a href="http://efficito.com/" target="_blank">http://efficito.com</a> -- Hosted accounting and ERP.</div><div>Robust and Flexible.
