I looked into this. The manual seems to provide the needed steps:

http://docs.mailman3.org/en/latest/migration.html#upgrade-strategy

What is suspicious is that they could not package this into a script,
and could not keep themselves from breaking the archive URLs.

This footnote is disconcerting:

http://docs.mailman3.org/en/latest/migration.html#id1

What I would like to do is get the archives and configuration files,
and write a script (probably a makefile) that does the import and
updates to the old HTML pages, and see if any of the potential
problems come up in any of the lists, and if there is an automated
way to deal with them. The script can then be used for the upgrade.
