We're looking for information on large sites that have migrated to mailman3. Preferably academic institutions. As we start to look at a migration project we're hoping to hear any 'lessons learned' from those who have gone before us.
The largest site I know of that has begun migration to Mailman 3, and has a non-trivial (dozens, maybe?) number of lists in operation is python.org. You can try searching the archives for this list and in mailman-developers@python.org for python.org and mailman3.org postmaster Mark Sapiro's opinions on the matter. I think the EMWD hosting site is also in process of migrating. I know there are several others (specifically a couple of academic institutions) basically at the very beginning of their migrations, but I don't know any in the later stages.
