Google Workspace to Microsoft 365 Migration

Moving from Google Workspace to Microsoft 365 is more than mailbox and file migration. We map users, groups, shared drives, calendars, permissions, collaboration habits, and identity settings into a Microsoft 365 operating model.

What this solves

  • Discovery for Gmail, calendars, Google Drive, shared drives, groups, permissions, ownership, and retention needs.
  • Target design across Exchange Online, Outlook, SharePoint, Teams, OneDrive, Entra ID, and governance.
  • Migration wave planning, user communications, validation, and post-cutover support for collaboration changes.

Why this matters

Migration risk usually hides in ownership, permissions, identity, workflows, integrations, and business validation. Our role is to surface those risks early, design the Microsoft target state, and guide the move with clear controls.

Map collaboration patterns

Translate Google Drive and shared drive usage into SharePoint, Teams, and OneDrive destinations.

Reduce user disruption

Plan mail, calendar, files, mobile access, desktop clients, and training around realistic cutover timing.

Establish governance

Set policies for sharing, retention, identity, Teams creation, and administration before users arrive.

Proof of fit

Representative scenarios we support

Buyers need to see that you understand their exact migration environment. These examples make the service tangible without relying on unverifiable metrics.

Tenant, SharePoint, Teams, OneDrive, Exchange, and Power Platform moves with real business validation requirements.
Migration programs where permissions, ownership, workflows, forms, integrations, or compliance constraints create risk.
Organizations that need senior Microsoft migration judgment, not only tool operation.

Before

What creates drag

  • Unclear scope, unknown owners, hidden dependencies, and migration waves based on incomplete inventory.
  • Technical migration success measured mostly by item counts, while business validation is left until late.
  • Legacy patterns copied into Microsoft 365 without improving governance, support, or ownership.

After

What good looks like

  • An inventory-backed plan with owners, dependencies, target architecture, validation gates, and remediation priorities.
  • Migration waves aligned to business processes, support readiness, communications, and go/no-go decisions.
  • A cleaner Microsoft operating model with governance, documentation, and post-migration support paths.
