Training session on MP Police Zimba and OS upgradation and integration 15 Dec 2023 - Tetra Support Staff - Manish Singh[edit]

Video summary: Detailed 32-minute walkthrough of the MP Police Zimbra project: a combined OS + mail server upgrade (CentOS 6.10 to 7.9, Zimbra 8.0.5 to 8.8.1, via intermediate hops) plus a set of new integrations delivered as part of the tender -- ActiveSync (mobile mail sync), RocketChat (client-requested open-source chat, replacing paid alternatives like Zoom/Webex for that need), an archival server (every inbound/outbound mail archived and retrievable, unlike Zimbra's own 4-day log retention), a Jitsi video-conferencing server (open-source alternative per tender requirements), NextCloud for file storage/sharing, an ELK server for centralized mail-server log monitoring/retention, a DR setup in a separate environment kept in sync via lsyncd, and a Barracuda spam filter in front of Zimbra. Also covers the scale (~96,000 users, ~140TB of data across incremental/full backups on dedicated large disks) and the recurring support pattern for this account -- routine Zimbra tickets plus periodic questions about accessing the archive, chat, or video-conferencing tools, all backed by documentation the presenter had written and was uploading to the wiki.
