Move mail, calendars, contacts, Drive files, and shared drives into Exchange Online, OneDrive, SharePoint, and Teams with a plan for coexistence, cutover, and the parts of Google that do not migrate on their own.
Migration workstreams
Leaving Google Workspace changes how people sign in, share files, schedule meetings, and find documents. We plan each of those, not just the data transfer.
Users, groups, aliases, shared mailboxes, delegated inboxes, resource calendars, shared drives, data volumes, and third-party apps that sign in with Google.
Email, labels, contacts, and calendars moved into Exchange Online in batches, with a routing plan so mail keeps flowing during coexistence.
My Drive content mapped to OneDrive and shared drives mapped to SharePoint or Teams sites, with folder structure and sharing reviewed first.
Accounts, groups, MFA, and apps that used Google as the identity provider re-pointed to Microsoft Entra ID before Google is switched off.
MX, SPF, DKIM, DMARC, and Autodiscover changes, final delta passes, mobile reprofiling, and a clear rollback point.
Short role-based onboarding for Outlook, OneDrive, and Teams so users are productive on the first morning, not the second week.
Most Google-to-Microsoft projects fail on people and edge cases, not on bandwidth. We pilot with real users, fix what they hit, then move everyone else in planned waves.
Plan the Google ExitWhere projects go wrong
These are the issues that most often surprise teams after a do-it-yourself Google Workspace migration.
A message with several Gmail labels can land in several Outlook folders, which inflates mailbox size and confuses users unless the mapping is decided up front.
Google-native files convert to Office formats. Comments, suggestions, and version history do not always come across, so active working files need a plan.
Migrated meetings keep their original Google Meet links. Recurring meetings owned by key people often need to be re-sent as Teams meetings.
SaaS apps that used Google as the identity provider stop working when Google accounts are closed unless they are moved to Entra ID first.
Google Sites, Forms, Apps Script automations, and Keep notes have no direct migration path and need to be rebuilt or retired deliberately.
Links shared with clients and partners from Drive do not carry over. Owners need a list of what to re-share from OneDrive or SharePoint.
