Mail, calendars, and contacts
Historical Gmail, calendar entries, and contacts move into Exchange Online with folder structure and labels mapped sensibly, so nobody has to go hunting for last quarter's thread.
Google Workspace to Microsoft 365 migration
A Google Workspace migration to Microsoft 365, without losing a day of email
A Google Workspace to Microsoft 365 migration handled end to end by senior US-based engineers: Gmail and calendars, Drive and shared drives into SharePoint and OneDrive, and a Teams rollout your staff can actually use. Priced as one fixed fee for the whole project rather than a per-user meter, typically delivered in 2–4 weeks, with 30 days of hypercare after cutover.
Representative dashboard — sample data
What you get
Everything your team touches daily, moved deliberately
Mail is the visible half of the job. The rest is files, permissions, and the habits people have built around them.
Drive and shared drives
My Drive content lands in each person's OneDrive; shared drives become SharePoint document libraries with an owner, a purpose, and permissions that match how the team really works.
Teams instead of Chat and Meet
Teams and channels are set up around the groups you already have, with meeting habits, file locations, and guest access configured before the first all-hands lands in Outlook.
Identity, domains, and DNS
Accounts, licenses, groups, and domain verification are prepared in advance, and MX, SPF, DKIM, and DMARC records are changed on a schedule you approve rather than discovered at 9am.
Cutover-day communication
Staff get plain-English notice of what changes, when, and what to do on the first morning — plus a named engineer to ask, so the help desk is not the only line of defense.
Documentation and 30-day hypercare
You keep a written record of the tenant, the mapping, and the DNS changes, and we stay on for 30 days to clear the permission and mobile-mail issues every migration produces.
How it works
Three steps from two platforms back down to one
- 1
Inventory and scope
A free consultation covers headcount, mailbox sizes, shared drives, domains, and any apps hanging off Google sign-in. You get a written scope, one fixed fee, and a cutover date before anything moves.
- 2
Pilot with a small group
A handful of volunteers move first. We check mail fidelity, file permissions, mobile devices, and Teams behavior against real work, then correct the plan while the stakes are still low.
- 3
Cutover and stay on
The bulk move runs, MX flips at an agreed quiet hour, a delta pass catches in-flight mail, and we remain available for 30 days of included hypercare while habits settle.
What the move actually involves
Two questions decide whether this project is worth starting: what it costs and how long it takes. We answer both in scope terms rather than a per-seat meter — the fee is fixed in writing after your free consultation and reflects how many mailboxes and shared drives are in play, how many domains you hold, and whether Drive content needs restructuring on the way in. Delivery is typically 2–4 weeks from kickoff, and the cutover itself is measured in hours, not days.
Under the hood, the content move uses Microsoft's own tooling. Migration Manager's Google Workspace migration path (opens in new tab) connects to your Google tenant, scans My Drive and shared drives, and copies content into OneDrive and SharePoint at scale with reporting on every item; Microsoft's admin guidance for switching from Google Workspace (opens in new tab) covers the mail and identity side. The tooling is not the hard part. Deciding where forty shared drives should land, who owns each one, and which of them should quietly retire — that is the work, and it is why a scoped project beats a weekend attempt.
What happens to shared drives, Sites, and mail on the day
Shared drives do not have a one-to-one twin in Microsoft 365, so each one is mapped to a destination on purpose: a SharePoint site with document libraries where a team genuinely collaborates, a library inside an existing site where the content is a subset of something bigger, or an archive where the drive is really just history. Google Sites content is reviewed the same way — usually rebuilt as SharePoint pages rather than copied, because the two platforms structure pages differently. Teams that want that destination designed properly, with navigation, metadata, and permissions rather than a flat dump of folders, usually fold this into our SharePoint intranet and document management work. Teams whose files live in Dropbox rather than Drive face the same mapping exercise, which we handle in our Dropbox to SharePoint migration service.
Mail is sequenced so nothing bounces. Historical mail and calendars are copied while Google is still the live mail host, users are briefed on what changes, MX records switch at an agreed low-traffic hour, and a delta pass sweeps up anything that arrived mid-switch. Larger organizations move department by department instead of all at once. Every fee for this work is fixed and stated in writing before you commit — our fixed-fee pricing and process page explains how the scoping conversation turns into that number.
The three phases of the project
Most migrations follow the same three phases. The table shows scope and typical timeline, not prices, because an honest number requires seeing your mailbox and Drive inventory first.
| Phase | Scope | Typical timeline | Fee |
|---|---|---|---|
| Phase 1 — Planning and mailbox mapping | Inventory of mailboxes, shared drives, domains, and Google-linked apps; tenant and license setup; a mailbox-by-mailbox mapping and a destination plan for every shared drive; the DNS change plan | About 1 week | Fixed fee — scoped after your free consultation |
| Phase 2 — Pilot migration | A small volunteer group moved end to end: mail, calendar, files, mobile devices, and Teams; fidelity and permission checks against real work; the plan and the user instructions corrected before anyone else is affected | About 1 week | Fixed fee — scoped after your free consultation |
| Phase 3 — Cutover, Teams rollout, hypercare | Bulk mail and content migration, MX cutover at an agreed hour, delta pass, Teams and channel rollout, staff guidance, admin handover, then 30 days of included post-cutover hypercare | 1–2 weeks, plus 30 days of hypercare | Fixed fee — scoped after your free consultation |
Everything lands in the tenant you own. Mailboxes, files, sites, Teams, and admin credentials are yours throughout, so you can carry on in-house the moment hypercare ends.

FAQ
Migration questions, answered
Scope covers discovery and mailbox mapping, tenant and domain setup, mail and calendar migration, Drive and shared drive content moved into SharePoint and OneDrive, Teams rollout, end-user guidance, and cutover support. The fee is fixed in writing after your free consultation and does not move unless the scope does.
Most migrations run two to four weeks from kickoff. A single-domain move with a handful of mailboxes lands at the short end; multiple domains, large Drive estates, or heavy shared drive restructuring take longer. Your written scope states the delivery window before you commit, and 30 days of hypercare follow.
Mail keeps flowing. We pre-migrate historical mail and calendars while Google still receives, then switch your MX records at an agreed low-traffic hour and run a delta pass to collect anything that arrived during the switch. Users get written instructions and a time window in advance.
You need one cutover moment for mail routing, not a lost day. MX changes happen at a scheduled quiet hour, often an evening or weekend, and most staff simply sign into Outlook the next morning. Larger organizations can move in batches by department so the risk stays small.
Yes. Mailboxes, files, sites, and Teams all land in the tenant your organization owns and administers. We work inside it with the access you grant, hand back full admin control at close, and hold nothing in our own environment, so you can continue in-house at any time.
For 30 days after cutover we handle the follow-on issues a migration creates: missing permissions, calendar quirks, mobile mail setup, shared drive links people still use, and questions from staff learning Outlook and Teams. It is included in the fixed fee, not billed as a separate support retainer.
