Turnkey Microsoft 365 Mailbox & Identity MigrationArwaz Khan
Most tenant migrations fail because engineers rush the DNS cutover or rely on manual web portal clicks. My migration methodology is built on pre-flight automated discovery, background staged synchronization, strict DNS SPF/DKIM/DMARC alignment, and dry-run validation.
Phase-by-Phase Deliverables:
Phase 1: Pre-Flight Audit & Identity Mapping
Automated source audit (Google Workspace, IMAP, or Tenant-to-Tenant), mailbox mapping, alias reconstruction, and TTL reduction to 300s 48 hours prior to cutover.
Phase 2: Staged Background Synchronization
Initial sync of 90%+ historical mail, calendar appointments, shared contacts, and folder structures over 3-5 days with zero user impact.
Phase 3: Domain Cutover & Mailflow Authentication
Weekend delta synchronization pass, MX record update, 2048-bit DKIM key publication, and DMARC p=reject policy enforcement.
Phase 4: Post-Migration Runbook & 7-Day Hypercare
Delivery of technical runbooks and 7 days of dedicated hypercare support.
Technical FAQs:
Q: Will my team experience email downtime during the cutover?
A: No. By pre-staging 90%+ of data in the background and lowering DNS TTLs 48 hours in advance, the final delta cutover happens seamlessly over a weekend with zero bounced mail.
Q: How do you handle shared mailboxes, distribution lists, and delegates?
A: I run custom PowerShell discovery scripts to extract shared mailbox permissions, delegate access, and distribution memberships, reconstructing them identically in M365.
Q: Do I need to give you permanent Global Admin credentials?
A: No. I operate under strict least-privilege principles using scoped Exchange Administrator roles or temporary MFA-protected administrative access revoked immediately upon completion.
