Hi,
So we tried to the migration following the steps:
- stop mailman in the old machine (v3.1.1 from ubuntu packages)
- dump DB mailman3 and mailman3web
- backup /var/lib/mailman3 content
On the new machine:
- checkout from git the version 3.1.1 to match production and install the
services
- stop mailman3 and mailman3-web on the new machine
- load DBs into new machine
- copy content from /var/lib/mailman3 into /local/mailman/var (which
means: archives/ cache/ data/ ext/ lists/ locks/ messages/
public_suffix_list.dat queue/ templates/ web/)
- start mailman3 and mailman-3web
- run mailman3-web migrate
And I stopped here. Because it crashed.
(venv) mailman@new-mailman3-server ~ (v3.1.1) [0|SIGINT]> mailman-web
migrate
System check identified some issues:

django.db.utils.OperationalError: (1050, "Table
'hyperkitty_mailinglist_moderators' already exists")
I tried to drop the table, but then it complained about another one. I
dropped all the complained tables and as result hypperkitty never
started. So I went back to see why the first error happened.
Any clue what to do next?
