Translating OneDrive Folder Permissions to Google Drive

Permission Mapping

Microsoft OneDrive allows for incredibly granular, item-level permissions that can be broken at any folder depth. Google Drive prefers a more simplified, top-down inheritance model via Shared Drives.

When migrating, it is crucial to audit OneDrive accounts for 'broken inheritance'. If a user shared a sub-folder with an external vendor, that sharing link must be accurately recreated in Google Drive. Migration engines handle this by reading the Access Control Lists (ACLs) in Microsoft Graph and writing corresponding permissions via the Google Drive API.
