Email Migration Services
Email migration services from any platform to Microsoft 365 — Exchange, Google Workspace, GoDaddy, Zimbra, Zoho, cPanel, hosted Exchange, or any IMAP server. One flat rate, one team, one verified outcome: $15/user with pre-staged sync, off-hours cutover, and 30 days of hypercare. 500+ migrations, 1.4 million users, zero data loss.

Every mailbox. Every folder. Verified.
What staying actually costs.
A "free" 50-mailbox migration costs 30-50 admin hours of batch babysitting and Monday-morning tickets. At any real hourly value, DIY is the expensive option.
A third of our projects start as stalled DIY attempts — stuck batches, broken Autodiscover, half-moved tenants. Starting managed is cheaper than being rescued.
The classic DIY failure: mail arriving at both old and new systems for weeks because cutover sequencing was improvised. We sequence DNS, delta, and decommission properly.
Done right, downtime is the 2-4 hour off-hours MX flip — data pre-stages invisibly for days or weeks beforehand.
Everything handled. Nothing assumed.
Any source platform
Exchange Server 2003-2019, Google Workspace, GoDaddy, Rackspace, Zimbra, Zoho, Kerio, SmarterMail, GroupWise, Lotus Notes, cPanel, and any IMAP host. If it holds mail, we migrate it.
Server-side, zero user action
Mail, folders, calendars, and contacts move server-side. Users keep working on the old system until cutover night — no client-side exports, no laptop collection.
Pre-stage + delta sync
Historical data copies in the background with nightly deltas. Cutover carries only the final few hours of mail — which is why weekends stay boring.
DNS + deliverability
MX, SPF, DKIM, DMARC configured properly on Microsoft 365 — many clients leave shared-host IPs and get a deliverability upgrade in passing.
Per-mailbox verification
Item counts verified per mailbox against source before the old system is decommissioned. Zero data loss across 1.4 million users, and we keep it that way.
30-day hypercare
Outlook profiles, mobile re-sync, the stragglers, and the "where did my folder go" tickets — covered for 30 days after cutover.
Assess. Plan. Migrate. Cutover.
Assess
1-2 days · Source audit, mailbox inventory, domain list. Fixed per-user quote in 24-48 hours.
Plan
1-2 days · Microsoft 365 tenant provisioned, domains verified, MFA + security baseline deployed.
Migrate
Background · Server-side pre-stage sync runs invisibly. Users keep working on the old system until cutover.
Cutover
2-4 hrs off-hours · MX/SPF/DKIM flip, final delta sync, Autodiscover repoint. 30 days hypercare.
The engineers on your project.
No outsourced ticket triage. The same three engineers handle source assessment, tenant provisioning, cutover night, and post-migration support on every Any Platform engagement.

MX/SPF/DKIM/DMARC cutover and Autodiscover repoint. Owns the 2-4 hour cutover window plus post-cutover Outlook profile and mobile device resync.
The Any Platform-specific realities.
Generic migration guides skip these. They are the operational details that decide whether your cutover weekend is boring — which is the goal.
Every source platform throttles differently — Google exports, hosted-Exchange EWS caps, shared-host IMAP limits — batch pacing strategy is chosen per source, not per tool brochure
Calendars and contacts are the fidelity risk, not mail — each source gets its verified export/import path rather than a mail-only migration that surprises users later
Cutover sequencing (MX, delta, Autodiscover, decommission) is where DIY migrations fail — ours is a written runbook executed off-hours, every time
