The route can include Gmail to Exchange Online, Google Drive to OneDrive, Google Contacts to Outlook Contacts and supported Google Calendar content. Google Photos complete-library migration uses a separate Takeout-based project because Google requires a user-created export.
Google authorization
A Workspace administrator supplies an authorized service account with domain-wide delegation for the selected organizational data. ElephantsData verifies the live APIs instead of assuming that a pasted scope is usable. Google Photos Takeout remains a user action and cannot be replaced by domain-wide delegation.
Cutover and incremental synchronization
Use a pre-stage migration for older content, review exceptions, then run the supported latest-changes operation near cutover. Provider quotas, source changes and Microsoft destination capacity can affect throughput, so large programs should be divided into monitored user batches.
