Google Workspace to Microsoft 365 Migration — Planned, Sequenced & Executed Without Business Disruption
Switching platforms is one of the highest-risk moments in a company's IT lifecycle — lost email, broken integrations, disrupted work. We manage the move to minimise that risk and keep your existing dependencies working.

What Moves — and What Requires Reconfiguration
A transparent breakdown of every component in your Google Workspace environment: what transfers automatically, and what is re-engineered for Microsoft 365.
What Moves (Full Migration Scope)
| Component | Source (Google) | Target (Microsoft 365) | Migration Protocol & Verification |
|---|---|---|---|
Emails & Mailbox Folders | Gmail / GWS Mailbox | Exchange Online / Outlook | All inbox emails, sent items, sub-labels mapped to Outlook folders, and archive mailboxes with zero data loss. |
Calendars & Meetings | Google Calendar | Outlook Calendar | Primary calendars, recurring appointments, attendee statuses, meeting notes, and descriptions. |
Personal Contacts & Address Books | Google Contacts (My Contacts) | Outlook People | Personal contacts, company details, phone numbers, notes, and custom distribution contact lists. |
Files & Shared Drives | Google Drive / Shared Drives | OneDrive / SharePoint | Personal Drive files migrate to OneDrive for Business. Shared Drives map directly to SharePoint document libraries with permissions. |
Domain Routing & DNS | Google Workspace DNS | Microsoft 365 Tenant | MX records, SPF, DKIM, DMARC security authentication, email aliases, and domain routing with dual delivery. |
User Identity & Security | Google Cloud Identity | Microsoft Entra ID | User accounts, security group memberships, Multi-Factor Authentication (MFA), and single sign-on (SSO). |
Our Approach to This Migration
A controlled, transparent rollout process tailored for Google to Microsoft transitions — built around zero operational disruption and full technical oversight.
Assessment first.
We map your current Google Workspace setup — data volume, mailbox structures, integrations, permissions, and dependencies — before proposing a plan. This isn't a generic checklist; it's what determines your specific migration sequence, timeline, and fallback approach. Nothing moves until we know exactly what's there.
Phased execution.
If you also need a full Microsoft security rollout (Entra, Purview, Defender), that happens as a sequenced next phase, not bundled into the same cutover window. Combining a platform switch with a full stack implementation in one go carries more risk than we're willing to take with your operations — so we sequence it deliberately, with validation checkpoints between phases.
On your systems, in view.
The migration runs where you can see it happen, not behind closed doors. Your data stays in your environment throughout — we're not routing it through a third-party pipeline you can't see into. You know what's happening at every step, with no surprises mid-migration.
Who This Is For
Whether you need a fully handled transition or a specialist migration partner working alongside your internal team.
Switching because of cost, features, or team preference?
We map your mailboxes, files, and integrations before cutover, so the switch doesn't cost you data or break what's already connected.
Have an internal IT team overseeing the switch?
We work as the specialist executing the migration, reporting into your process.
Frequently Asked Questions
