Training on PAHWA (BRYAIR) BSP Mail Server Magiration. Dated 20 July 2026 - Tetra Support Staff - Takshay[edit]

Video summary: "PAHWA (BRYAIR) BSP Mail Server Migration KT session" -- a Hindi-language internal KT recording walking through a Zimbra migration for client Pahwa (Bry-Air). Covers: the four Zimbra BSP subscription tiers (Business, Business Plus, Standard, Professional) and confirming the client is on Business; provisioning a new Ubuntu 22.04 server with local DNS via dnsmasq and verifying it with host/nslookup; a single-server Zimbra install (10.1.19 at the time) following the official install guide; post-install license activation -- creating a "Business" Class of Service, setting it as the domain default, and manually re-assigning the pre-existing admin account to that COS since new users inherit the domain default but the original admin doesn't; activating the license via the admin UI or the `zmlicense -a` backend command; creating ~900 mailboxes with `zmprov ca`, batched into scripts of 100 users each; migrating user passwords by exporting them from the old server with `zmprov gap` and replaying the output on the new server so credentials transfer unchanged; migrating mailbox data via imapsync (installed either side, run from the destination in this case) using admin-to-admin authentication; going live and installing Zert to monitor per-client license/feature usage against what's actually been purchased (e.g., catching a client using Professional-tier features while paying for Business); and finally describing Pahwa's secondary DR server, which runs the same Zimbra version under a DR license with weekly (not live) imapsync replication, plus the standard Zimbra Network Edition default backup schedule (incremental Monday-Friday, full backup Saturday night, three cron-driven backup scripts, 30-day retention).
