Microsoft 365 · Tenant-to-tenant migration

M365 Tenant-to-Tenant Migration. Fixed price. Zero data loss. Done in days, not months.

A done-for-you migration service for small businesses (20–200 users) going through a merger, acquisition, or tenant consolidation. You never touch a migration tool — you talk to the engineer who runs it.

Why DIY migrations fail

The tools exist. The expertise to configure them correctly doesn't come free.

Roughly 12% of self-managed migrations result in data loss. The failure modes are predictable — and expensive.

Lost data

Mailboxes, OneDrive files, and Teams history silently dropped when mappings and throttling aren't handled correctly.

Broken permissions

SharePoint and shared-mailbox permissions don't survive a naive copy — users lose access on day one.

Downtime & mail loops

Botched DNS cutover means bounced mail and a scramble while the business waits.

Most small companies can't justify a $6K–18K/year ShareGate license or dedicate internal experts to a one-time project. That's exactly the gap this service fills.

What's included

One fixed scope. Everything a clean cutover needs.

Pre-migration assessment

Tenant readiness report before any data moves.

Identity mapping & licensing

User identity mapping and license provisioning in the target tenant.

Exchange Online mailboxes

Full mailbox migration, including shared mailboxes.

OneDrive & SharePoint

Document migration with permissions preserved.

Teams

Channels, files, and chat history.

DNS cutover & mail flow

Planned cutover with mail flow configured correctly.

Post-migration validation

Verification pass before you sign off.

30-day monitoring

A support window after cutover, included.

Under the hood we use BitTitan MigrationWiz and Microsoft native tooling — you never touch them.

Identity mapping, license provisioning, and a scheduled cutover window agreed with you.

Migration

Mail, files, SharePoint, and Teams pre-staged with BitTitan and native tooling.

Validation

DNS cutover, verification pass, and 30 days of monitoring after you sign off.

FAQ

Straight answers.

How long does a migration take?

Most 20–200 user migrations complete within days. After the assessment you get a scheduled cutover window; mailboxes, files, and Teams data are pre-staged so the final cutover is fast.

Is my data safe?

Yes. We migrate in stages and validate before cutover. Source data is copied, not moved — nothing is destroyed during the migration.

How much downtime should we expect?

Near-zero for users. Mail flow is cut over during a planned window and data is pre-synced, so users typically resume in the new tenant the same day.

What happens to the source tenant?

It stays intact until you confirm the new tenant is validated. You decommission it on your own timeline; we can advise on license wind-down.

Can you handle compliance holds and eDiscovery?

Yes — as an add-on we preserve compliance holds and eDiscovery content throughout the migration.
