[MM3-users] OS upgrade - anything to take care of?

Dear MM3 users,

today I upgraded one of two servers from Ubuntu 18.04 to 20.04 and - besides some minor config updates - postfix & dovecot worked well afterwards.

So I am very optimistic that the upgrade of the second server from 18.04 to 20.04 will also work fine. But the second server is running MM3 (installed in venv) and I saw that on upgrade Python 3.8 is installed.

Is there anything I have to take care of? Anything to do / change in venv?

Kind regards Torge
