What are the steps for migrating a half dozen lists with subscribers from an old server (Debian 10) to a new server (running Debian 13) please?
It's a lot easier if you used the virtualenv install method <https://docs.mailman3.org/en/latest/install/virtualenv.html> on the old server. Dump the DB on the old server and import into the new server. Install everything in the new server as you installed on the old server and carry over the folders from the old to the new server. Then you need to run database migrations - https://docs.mailman3.org/en/latest/install/virtualenv.html#run-database-mig... and those other commands below it. If you installed using Debian packages, then, err, it's another ball game.
