Why email cutovers go wrong
Rushed migrations lose mail, break calendars, strand shared mailboxes, and push your whole domain into recipients' spam folders because SPF, DKIM, and DMARC were not staged. The damage shows up after the switch, when it is hardest to undo.
What's included
Platforms: Microsoft 365, Google Workspace, Zoho, on-prem Exchange, cPanel webmail, in any direction
Full inventory first: mailboxes, aliases, distribution lists, shared mailboxes, calendar resources, mobile devices
License sizing, a pilot migration, and a bulk sync before cutover
A timed cutover window with verification at every step
DNS done right: MX, SPF, DKIM, and a staged DMARC policy so legitimate mail keeps flowing during the transition
Four scheduled end-user communications and Day 1 helpdesk triage
What you receive
A complete cutover runbook with rollback triggers, plus a signed post-cutover sign-off. You keep the documentation.
Where we stop
In scope: the migration project and its cutover. Out of scope: ongoing tenant administration, security incident response, and complex hybrid coexistence. If you need those, we will tell you and point you to the right partner.
Email migration FAQ
Will we lose any email during the move?
No. We run a pilot, a bulk sync, and a final delta sync, and we keep the source mailboxes available as a fallback until delivery is fully stable.
How long does a migration take?
It depends on mailbox count and total size. We scope the timeline in discovery and run the cutover in a planned window, usually outside business hours.
Will our email land in spam after switching?
Not if DNS is staged properly. We publish SPF and DKIM early and move DMARC in stages so legitimate mail is never bounced mid-transition.
