No. It is perfectly fine to support both Mailman 2.1 and Mailman 3 on the same server with the same domain(s). The process is install and test Mailman 3 on the server with one or more test lists. After you are convinced that Mailman 3 is OK, migrate the Mailman 2.1 lists. I've attached `migrate_list` which is the bash script I used to migrate this list and many other MM 2.1 lists to MM 3 on mail.python.org. It has lots of mail.python.org specific stuff in it, but you should be able to modify it for your environment. The script does one list and it runs fairly quickly, so you can run it without shutting anything down as long as it's at a time when there are no posts to the list, and if you're concerned about arriving posts, you can stop the MTA while running the migration. -- Mark Sapiro <[email protected]> The highway is for gamblers, San Francisco Bay Area, California better use your sense - B.
