Greetings all -
My current build is running Mailman version: 2.1.20, on a long-in-the-tooth Scientific Linux release 7.9 (Nitrogen), with sendmail
I'd like to go RHEL9, and Mailman 3.3.8 (Tom Sawyer), with postfix, on a new parallel VM - plan is to build a parallel server, same hostname, different IP, migrate all data/archives and billing info (we have that scripted), then do a dns change to point to the new IP after testing.
Are there any means of scripted migration from old to new? Can I go from 2.1.20 direct to 3.3.8 - or do I need to go to 2.1.39 as an intermediate first?
It's a service we provide, and we like to keep the our level of interaction to a minimum, so 2.1.20 was the first built "I" did back when RHEL7/SL7 was in it's early days. Going latest would fill that mold for us for a while.
I'm currently looking at the wiki.list.org, but am having troubles locating Mailman3. version Site Admin doc - they seem to be v2.1 - I could be missing them. I'm old.
