A few mails are lost in the migration from 2.1
So just to be sure I purged the old import, and also launched the command manually instead of import-mm2.py to be sure I got all potential warnings and error messages:
# sudo -u mailman mailman3 remove firstname.lastname@example.org Removed list: email@example.com # sudo django-admin hyperkitty_import --pythonpath /var/www/mailman/config --settings settings -l firstname.lastname@example.org --no-sync-mailman /var/lib/mailman/archives/private/users.mbox/users.mbox |tee ~/20170621-01_mailman_migration__users.log Importing from mbox file /var/lib/mailman/archives/private/users.mbox/users.mbox to email@example.com Computing thread structure Warming up cache The full-text search index will be updated every minute.

So everything seem to be fine except 61 mails are missing for this specific ML.
Over all the oVirt MLs, 102 messages were lacking a Message-Id in the Mailman 2.1 mbox files, so it caused an error during import and I made a script to add a fake one, so at least it is imported even if the thread cannot be reconstituted. There is a total of 321 messages missing in this installation, so more than the updated posts, and, after checking, I honestly don't think my script is at stake here.
An example is this mail: https://mail.phx.ovirt.org/archives/list/users%40lists.ovirt.org/message/BU2QU4UIIQAPCVZCWABF63K7LEWU2FNN/ It is a reply to a mail which is in the 2.1 mbox but silently not imported. Using the UI search function I could not find it. I looked into the message table of the mailman database and also in the hyperkitty_email table of the hyperkitty database and found no trace of it using its Message-Id.
Attached is the missing mail; I could not find why it would be skipped. mm3_migration_skip_eg.txt
Would you please give me a hand? _o<
