Hello.
Have 4 Debian servers running Mailman3 v3.2.1 and sharing the same external MySql databases for Mailman3 and Mailman3-web. I am in the process of migrating to v3.3.3. It would be easiest to perform this upgrade one server at a time, but this would mean that for a short time I would have v3.2.1 and v3.3.3 using the same databases.
You could {dup|trip|quadrup|-locate the databases and point each server to a different one temporarily.
