Hi all,

I am running a relatively old version of mailman 3, namely 3.2.0a1 from late september 2017. This is installed using the old mailman-bundler method. I use postfix and postgres.

I really have two questions:

First: What is the normal way to upgrade such a setup? I guess that I just can get the updated versions of all packages through git, set up new venv's to simplify a rollback, back up the database and then just restarting with the new version hoping for the best.

Second: Another way would be to set up a new virtual server and reinstall everything and then just switching IPs on the servers. Then: what is the preferred way to install mailman3 today, docker only? I will also have to move all config and data to the new server, this should be mainly about restoring a database backup and copying relevant config, is there anything I miss here?

cheers // David
