Google Workspace to Microsoft 365 Migration

Moving from Google Workspace to Microsoft 365 changes how people store files, share documents and run meetings. RHC migrates Gmail, Drive, Calendar and Contacts, and prepares your team to work in Outlook, OneDrive, SharePoint and Teams from the first day.

The challenges

  • Gmail labels have to become Outlook folders without duplicating messages.
  • My Drive and Shared Drives map to different places: OneDrive for personal files, SharePoint or Teams for shared ones.
  • Docs, Sheets and Slides have to be converted to Word, Excel and PowerPoint.
  • Internal and external sharing has to be recreated so people keep access to what they use.
  • Users used to Google need training, or the first weeks fill up with frustration and support tickets.

How we do it

  1. 1Assessment: users, mailbox sizes, Drive and Shared Drive volume, third-party apps and integrations.
  2. 2Design: Drive-to-OneDrive and Shared Drive-to-SharePoint/Teams mapping, cutover plan and identity setup.
  3. 3Microsoft 365 preparation: tenant, domains, licenses, security baseline and Entra ID.
  4. 4Pilot: a small group migrates first to validate conversions and user experience.
  5. 5Pre-staging: historic email and files are copied while users keep working in Google.
  6. 6Cutover: MX change, final delta sync, Outlook and OneDrive setup on devices.
  7. 7Adoption and hypercare: training sessions, quick guides and support in the first weeks.
