Training on PHDCCI Migration. Dated 29 Feb 2024 - Tetra Support Staff - Biswajit Banerjee[edit]

Video summary: Walkthrough of the PHDCCI mailbox migration from Google Workspace to Microsoft 365 (~300 users, ~1TB of data), done as a user-to-user IMAP migration rather than admin-to-admin because the client's existing Google Workspace vendor would only provide a restricted admin account, not full rights. Covers: purchasing M365 licenses first, creating an IMAP migration endpoint against Google's IMAP server, building the CSV batch file (Microsoft username / Google Workspace username / Google Workspace password) via the Exchange admin panel's migration wizard, temporarily disabling each account's 2FA "login challenge" (a 10-minute window) so the sync can authenticate, adding the domain and letting Microsoft auto-configure MX/SPF DNS records, and troubleshooting failed batch entries (almost always a changed password) by deleting and re-running just that user. Also covers enabling IMAP access on the Google Workspace side (it wasn't originally enabled, since the client used the Gmail web UI directly) and disabling MFA org-wide post-migration at the client's request.
