ShareGate Migrate relies on available Google and Microsoft APIs to move your Google Drive content to SharePoint, and there are a few limitations to consider.
General limitations
When migrating folders from shared drives, the Created by metadata value is replaced by the last Modified by value at the destination.
Migrate does not copy files shared with a guest or shareable link with the link. Users will have to re-share these files at the destination.
To learn how to share your files in SharePoint, see the Microsoft article Share SharePoint files or folders.
Google Docs files are exported and updated by Google to work in Microsoft Office and might appear different at the destination.
Your users will not find files shared with them in a Shared with me view unless your migration destination is a OneDrive for Business environment that does not use the modern experience.
Migrate replicates your Google Drive access through a set of permissions. Your users will have access to the files even though they won't find them in a view.
Note: Limitations from your SharePoint destination could apply.
