Cloud email migrations without the disruption

Mac Support London moves organisations between Google Workspace, Microsoft 365, and hosted Exchange—off shared reseller tenants and into secure environments you control.

Plan a migration

When businesses call us

  • Moving from Google Workspace to Microsoft 365 (or vice versa) with zero mail loss.
  • Escaping shared reseller tenants (GoDaddy, 1&1, Fasthosts) into dedicated, admin-controlled tenants.
  • Merging multiple domains into one platform after a merger or restructure.
  • Retiring legacy on-premises Exchange or IMAP services.
  • Splitting a company into separate tenants with clean licensing and security boundaries.

Platforms we migrate between

  • Google Workspace ↔ Microsoft 365
  • Hosted Exchange / POP / IMAP → Microsoft 365 or Google Workspace
  • Shared Office 365 tenants → dedicated Microsoft Cloud tenants
  • Microsoft 365 GCC / UK sovereign regions
  • Dropbox, Box, and other cloud storage into SharePoint / Google Drive / Synology C2

How our migrations run

  • Discovery & readiness – inventory mailboxes, storage, apps, and identity, then produce a migration runbook.
  • Pilot – move a handful of users, validate devices (Mac, iOS, Windows), and tune settings.
  • Data copy – staged or cutover moves using BitTitan, CloudM, or native tools with throttling controls.
  • Cutover – DNS, MX, and SPF/DKIM/DMARC changes scheduled for low-traffic windows.
  • Hypercare – floor-walking, remote support, and documentation for admins.

Protecting your data throughout

  • Immutable backups of source mailboxes and shared drives before we touch DNS.
  • Conditional Access, MFA, and secure defaults applied to the new tenant.
  • Audit logging, export of mail flow rules, and documentation of every change.
  • GDPR-compliant handling of PST/mbox archives, litigation holds, and shared mailboxes.

What you get

  • Project plan with owners, timelines, and rollback criteria.
  • Communication pack for end users (FAQs, training links, login instructions).
  • Post-migration health report, licensing tidy-up, and admin handover session.
  • Optional managed support agreement for ongoing care.
