One of sites which I admin lived on hosting providers server which was powered with CPanel and I moved it on VPS few days ago. I had tar file which was CPanel’s full backup of host. Emails and website was easy to migrate from that backup because tar contained all emails on Maildir format and whole website was on one folder. Mailing list migration was more trickier because of CPanels patched version of Mailman.
I found this helpful Mailman migration article, but it was for normal Mailman setup and steps are little bit different if you are moving away from CPanel. I didn’t find too much information of CPanel’s Mailman so I wrote this small tutorial for other admins who are moving away from CPanel and have to migrate their mailing lists to standard Mailman setup.
