Migration to Microsoft 365
A seamless migration from Google Workspace to Microsoft 365 for an aerospace supplier. Complete data transfer, user profile migration, and security hardening—with zero downtime and no lost productivity.
Platform Lock-In and Security Gaps
This aerospace supplier had been using Google Workspace since their early days. As they grew and began working with larger defence contractors, they faced pressure to move to Microsoft 365—both for compatibility with client systems and to leverage the security features in Business Premium.
The migration presented several challenges:
- Years of accumulated data in Gmail, Drive, and Google Docs
- Complex folder structures and sharing permissions
- Staff comfortable with Google and resistant to change
- Critical business operations that couldn't tolerate downtime
- Need for proper security controls post-migration
- Compliance requirements for aerospace supply chain
They needed a partner who could execute the migration flawlessly while also establishing proper security foundations for their new environment.
Phased Migration with Parallel Running
We designed a migration strategy that allowed both platforms to run simultaneously during the transition, ensuring zero disruption to operations.
| Google Workspace | Microsoft 365 |
|---|---|
| Gmail | Outlook + Exchange Online |
| Google Drive | OneDrive + SharePoint |
| Google Docs/Sheets | Word/Excel Online + Desktop |
| Google Meet | Microsoft Teams |
| Google Calendar | Outlook Calendar |
Migration Process:
- Full audit of existing Google Workspace environment
- M365 tenant setup with security baseline configuration
- Batch migration of email archives (nights and weekends)
- Drive to OneDrive migration preserving folder structures
- Shared Drives to SharePoint team sites with permission mapping
- Calendar and contact synchronisation
- Parallel running period with mail forwarding
- DNS cutover with monitoring
- Staff training on new platform
Seamless Transition, Enhanced Security
