MPonline

Training about MPonline project. Dated 10 March 2022 - Tetra Support Staff - Pappu

Video summary: General training session (not client-support-call style like most others) walking a newer team member through the standard end-to-end process of standing up and migrating a Zimbra Network Edition mail server, using the MPonline project as the working example. Covers: pre-checks (disk space, setting a proper static hostname via hostnamectl/hosts file/DNS entries), disabling SELinux and firewall rules that would block Zimbra, removing conflicting pre-installed services like Postfix (since Zimbra ships its own MTA), downloading the correct Zimbra tarball version via wget, running the installer and setting the admin password, backing up and restoring Zimbra's mailbox index/store data between an old and new server (via rsync, followed by fixing ownership to the zimbra user and reindexing), migrating user passwords across via zmprov, activating the Zimbra license (zmlicense), and general tips: using `screen` to keep long-running migration commands alive across a dropped SSH/RDP session, and referencing separate recorded sessions (by other team members) that cover the DNS/BIND configuration and live-cutover/downtime process in more depth.
