SharePoint or Google shared drives when migrating a team library

If every member of a destination team should see the same working library, a Google shared drive’s default member access is a useful starting design. If the migration needs separate external-facing and confidential spaces, plan SharePoint sites with different sharing settings and test membership at each site. Google can also share folders with non-members and use limited-access folders, so the final choice depends on the actual access map. For a SharePoint-to-SharePoint move where older versions must remain available, Microsoft’s in-service Move to command has a documented version-preservation advantage over copying through File Explorer.

Decision point	SharePoint team site	Google shared drive
Default team boundary	A SharePoint team site holds shared team files; a separate site can keep confidential content closed to external sharing. Microsoft Microsoft external sharing	Shared-drive members normally see the drive’s files; limited-access folders require deliberate configuration. Google
External access after a move	Test site and file sharing with an actual guest account. Organization-level permission alone does not mean every new site permits the same sharing. Microsoft	Drive restrictions can override a file’s existing external share when it moves into the drive. Google
Revision history	Move to within SharePoint preserves versions; File Explorer copying does not. Microsoft	Test what the selected cross-platform migration method actually imports; these sources make no preservation promise.
Existing links and metadata	Inventory live links and fields before the move, then compare destination files.	Perform the same inventory and readback; neither destination repairs old URLs by assumption.

Draw the access map before choosing a migration tool. Mark files for all team members, only the project group, and outside reviewers. A shared drive’s broad default member visibility can simplify a uniform team library but needs a deliberate exception for restricted material. In SharePoint, an external-facing site can be separated from a site whose external sharing is off. Microsoft’s guidance recommends separate sites for confidential information that should not be shared outside. This is an architecture choice; ask a second account to confirm the effective access in the candidate setup.

Permissions deserve a test with actual accounts. Google notes that moving files into a shared drive can change external access because of drive restrictions. Google A realistic failure is an outside reviewer opening a familiar file link after the move and finding that access has changed. Include an external collaborator in the pilot if the team relies on one, and have the destination administrator check restrictions before treating the result as a migration error. For either destination, record who could open a sample file before the move and have those same people try the destination file afterward.

Keep version history separate from file content in the migration plan. Microsoft says copying or moving SharePoint files through File Explorer does not preserve SharePoint versioning, while using Move to within SharePoint does. Microsoft That guidance does not establish what a cross-platform migration transfers. If earlier revisions matter, select a file with a known revision history and inspect the destination result. Do the same for source metadata your team depends on, such as dates or attribution, without assuming a migration tool preserves it.

Before the pilot, decide how long the source remains available for comparison and whether any retention requirement applies to the files. Confirm the destination’s applicable rules with its administrator; these sources do not establish equivalent retention settings or a cross-platform transfer of past versions.

Pilot one small, representative folder containing a shared link, a restricted file, an externally used file if applicable, and a file with prior revisions. Record its owner, access, links, metadata, and versions before migration. Afterward, ask the intended users to open the files and links, compare the recorded fields, and list every difference. Choose the destination and migration method only after the team accepts those results or has a specific remedy for each gap.
