[MM3-users] Mailman - delete or backup old archived messages

Hello Mailman team!

I have been using Mailman-Suite (Hyperkitty + Postorius) quite a long time now and now i was wondering if there is any way to erase or export old archived messages and back them up elsewhere (for example messages, that are older then 1 year). Didnt find any suitable option under "python3 manage.py" command and also didnt find any up to date post which related to mailman3 and python3.

Additional info: *Database: Postgresql13 *Mailman version: 3.3.4 *Python version: 3.6
