Cloud & Email Migration

Cloud and email migration without a weekend outage

We move mail, calendars, files, identities and the devices people sign in on between platforms: Google to Microsoft, Microsoft or Google to Zoho, Zimbra to Microsoft. More than 300 migrations delivered, planned so the old platform stays live until the new one is proven.

The challenge

What actually breaks in a migration

The mail usually arrives; what breaks is everything attached to it, from Outlook profiles and shared mailbox permissions to delivery routing.

Big bang cutover

A single weekend switch leaves mail queued at the old host while DNS propagates, and anything that fails has no path back.

Monday at the helpdesk

Every user rebuilds an Outlook profile by hand, re-adds shared mailboxes, and redownloads years of mail, so the first day back is the outage.

Only the mail moves

Mailboxes land, then delegates, calendar permissions, distribution lists, room resources and archives turn out to have stayed behind on a platform you already canceled.

How we do it

Synchronized first, switched second.

Four stages, built so every mailbox is synchronized before anything changes and the old platform stays live until the new one is proven.

Map the tenant

Mailbox sizes and item counts, shared and resource mailboxes, delegates, distribution lists, public folders, archives and Drive shares, plus the stale accounts worth leaving behind.

Pre-stage and keep syncing

We seed every mailbox into the target platform and keep it in delta sync while the old one stays in use, so cutover copies only the last few hours of mail.

Move identity and devices

Entra ID user profiles and the machines people already own move with the mailbox, and Outlook reconfigures itself on first launch, so no one rebuilds a profile or re-adds a shared mailbox.

Switch routing, then verify

MX, autodiscover, SPF, DKIM and DMARC are published for the new platform and checked after cutover, with the old tenant kept alive until every mailbox, rule and forwarder is confirmed.

Tools we use

Platform-neutral, chosen to fit your estate.

We deploy and operate what suits your environment and licensing, rather than reselling one stack to everybody.
