Microsoft 365 Migration Services
At Lanter, our Microsoft 365 migration services are built around careful planning, practical execution and a smooth cutover experience for your team.
Whether you are moving from another email platform, consolidating tenants, or changing domains and email addresses, we work through the moving parts carefully so the transition runs as expected.
Key Benefits of Our Microsoft 365 Migration Services
The Right Approach
Every Microsoft 365 migration is different. We assess your users, systems and risk profile before recommending how the move should be handled. Not every business suits the same model.
Cutover or Staged?
Some environments suit a planned weekend switch. Others are better moved in stages to reduce risk. We explain the trade-offs clearly and recommend what fits your timing and complexity.
Preparation That Prevents Problems
Most migration issues stem from missed setup details. We review accounts, permissions, DNS, licensing and dependencies before the move so day one runs as expected.
Domain and Email Changes Managed Properly
If your migration involves changing domains or email addresses, it needs careful planning. We manage verification, routing and timing so email continues flowing correctly.
Third-Party Access Considered Early
Many platforms rely on Microsoft sign-in. We identify these dependencies in advance to avoid login or access issues after migration.
Email History Protected
Users expect their past emails, contacts and calendars to work immediately. We migrate mailbox data carefully and address common issues like saved addresses and replies to older emails.

Why Businesses Trust Lanter for Microsoft 365 Migration Services
A Pragmatic, Business-First Approach
We don’t treat Microsoft 365 migrations as purely technical projects. We look at how your business operates, what systems are critical and when your teams are busiest before planning the move.
That means timing the migration properly, communicating clearly with stakeholders, and making decisions that prioritise continuity.
Experienced Specialists With Real-World Perspective
Microsoft 365 migrations often involve more than moving mailboxes. Shared accounts, authentication methods, domain settings and application integrations can all introduce risk if not handled properly.
Our team has delivered migrations across a range of business environments and understands where issues typically arise. That experience allows us to anticipate complications and resolve them before they affect your users.
Honest Advice Focused on the Right Outcome
Not every organisation needs a staged migration. Not every environment is suited to a fast cutover.
We explain the practical differences clearly and recommend what makes sense for your user numbers, complexity and risk tolerance. Our advice is based on experience, not on adding unnecessary layers to the project.
Microsoft 365 Migration Services for all Business Sizes
Microsoft 365 Migration Services for Small Businesses
For smaller teams, a migration is often about moving off legacy email, tidying up years of inconsistent setup and getting everything working properly in one go. A well-planned weekend migration is usually the right fit. With the preparation done properly, your team logs in on Monday and gets straight back to work – without juggling two systems or managing a prolonged changeover.
Microsoft 365 Migration Services for Medium Businesses
Growing organisations typically have shared mailboxes, third-party apps, multiple device types and more internal dependencies. That’s where migrations become less straightforward.
In these environments, a staged move often makes more sense. It allows us to test with a smaller group first, resolve issues early, and then confidently roll out to the wider business.
Microsoft 365 Migration Services for Large & Multi-site Organisations
Multi-site or more complex environments often involve multiple teams, legacy configurations and application integrations that need to remain stable throughout the migration.
These moves require careful coordination and clear communication. We structure the rollout in phases and manage the transition methodically, so operations continue running while the change happens in the background.
Frequently Asked Questions
What does a Microsoft 365 migration include?
A Microsoft 365 migration typically includes mailbox, calendar and contact migration, domain configuration, user account setup and cutover execution. We also assess third-party app sign-ins and security settings.
Should we use a cutover or staged migration?
Cutover migrations suit smaller, lower-risk environments. Staged migrations reduce risk in more complex environments and allow controlled testing before full transition.
How long does a Microsoft 365 migration take?
Timeframes depend on user numbers, data volume and complexity. Small cutovers may be completed over a weekend. Staged migrations may run over several weeks.
Can you migrate us if our email address or domain is changing?
Yes. We manage domain verification, DNS updates and alias configuration to ensure a smooth transition when email addresses change.
Will our email history, calendars and contacts be migrated?
Yes. We migrate mailbox data carefully to ensure continuity and minimise disruption.
What happens to Outlook autocomplete and old email replies after migration?
We address common issues such as autocomplete not transferring and reply behaviour failing due to address changes, ensuring these are planned for in advance.
Will our users be able to sign in to third-party apps after the move?
We assess single sign-on and third-party dependencies before migration to reduce login disruptions.
Can you help with Microsoft 365 setup, security and licensing after migration?
Yes. We provide ongoing Microsoft 365 setup, security configuration and licensing advice after migration.
