Training on ISONBPO & SYSNET GLOBAL BSP KT Session. Dated 20 July 2026 - Tetra Support Staff - Takshay[edit]

Video summary: Detailed 37-minute KT session covering the combined Zimbra Business Edition setup for two separate clients, ISON BPO and SysNet Global, consolidated onto shared infrastructure fronted by a single HAProxy server. Topics: migrating both from Zimbra open-source to Network/Business Edition (critically, always creating and assigning the Class of Service *before* activating licenses or creating users, to avoid accounts defaulting to the far more expensive Professional tier); password migration from the old servers via a generated zmprov batch of "SetPassword" commands; data migration via imapsync run with multiple parallel threads and a persistent local cache directory (avoiding a full re-sync if the process is interrupted/restarted); and the HAProxy configuration itself -- a single shared URL/IP with custom, non-standard ports (1000 for ISON, 2000 for SysNet) used specifically to let a subset of users without smartphones or the technical ability to set up an authenticator app bypass the otherwise-mandatory two-factor login. Also covers the custom Flask-based single-sign-on-style login landing page (backend on port 5000, proxied through HAProxy on 443) that fronts both clients' mailboxes, an LDAP-driven script that keeps that login page's user list in sync automatically, and Let's Encrypt SSL certificate generation/renewal for the setup.
