Migrations that keep your team working
Mail, files and sign-in all have to move together. We plan the order, run the moves and support users afterward.
Exchange Online and email
Mailboxes, calendars and contacts moved from on premises Exchange, hosted email or other platforms.
SharePoint and OneDrive
File servers and shared drives moved with structure and permissions planned first.
Tenant to tenant moves
Consolidate or separate Microsoft 365 tenants after a merger, sale or reorganization.
Google Workspace to Microsoft 365
Mail, calendars, contacts and files moved from Google with a staged plan.
Domain and DNS cutovers
Mail flow and DNS records changed on a schedule that limits disruption.
Identity migration
Users, groups and sign-in moved to Entra ID with MFA set up as part of the project.

How the work runs
A predictable process with written scope and a plan before any change.
Discover
We review users, mailboxes, data volumes, domains, licensing and any integrations or applications.
Plan
You get a migration plan, cutover schedule and written quote, with a communication plan for staff.
Pilot and migrate
We start with a pilot group, then move the rest in planned batches.
Cut over
Mail flow and DNS are switched on a planned date, with testing before and after.
Support
We help users after the move and clean up anything left behind.
Merger and acquisition moves
For tenant moves after an acquisition, see how we handled one in our customer story. Every tenant to tenant project is different, so we scope it after reviewing both environments.

Common questions
How long does a Microsoft 365 migration take?
It depends on the number of users and the amount of data. We give you a timeline in the plan after discovery.
Will our email be down during migration?
We plan to keep mail flowing throughout. Cutovers are scheduled and tested to keep any interruption short.
Can you migrate from Google Workspace?
Yes. We move mail, calendars, contacts and files in a staged plan.
Can you move our file server to SharePoint or OneDrive?
Yes, where it fits your workflows. We design structure and permissions first, then migrate in stages.
Can you merge two Microsoft 365 tenants?
Yes. Tenant to tenant migrations are planned in phases covering mail, files, Teams, users and devices.
Do you help users after the move?
Yes. We provide support and answer questions during and after the cutover.
