Migration of archives mailman2 to mailman3: python: can't open file '/opt/mailman/manage.py': [Errno 2] No such file or directory
Your current *) documentation says
Migrate the list archives from Mailman 2 to Mailman 3 by running the following command:
$ python manage.py hyperkitty_import -l foo-list@example.com $var_prefix/archives/private/foo-list.mbox/foo-list.mbox(venv) /opt/mailman $ python manage.py python: can't open file '/opt/mailman/manage.py': [Errno 2] No such file or directory
What did I wrong or what is that part of your documentation missing?

Substitute mailman-web for 'python manage.py':
(venv) /opt/mailman $ mailman-web hyperkitty_import -l foo-list@example.com $var_prefix/archives/private/foo-list.mbox/foo-list.mbox

Thank you very much.
Shall I (or you?) fix that in the documentation, at least as third footnote?

See the note in the first section at https://docs.mailman3.org/en/latest/

The documentation doesn't always say so, but the Django admin command
may be called manage.py or not depending on how you installed Django. If
you installed following
https://docs.mailman3.org/en/latest/install/virtualenv.html, i.e.
installed mailman-web, instead of python manage.py the command is just
django-admin.

Or, as Odhiambo says, mailman-web which is probably better as
django-admin may not find your settings file.

Success!!
Everything - apart from 2 bugs I will report later separately - went smoothly an I could migrate mailinglists and archives of ~30 mailman2 lists to a new server and to mailman3, in total it was ~ 12 GB.
I will later help to improve your documentation in those places, where it is wrong or where information is lacking.
