What Changes to Permissions When Migrating from Google Drive to SharePoint?

Posted at 23:05h in Blog by Prashanth M 0 Comments

When moving from Google Workspace to Microsoft 365, most people focus on transferring files. But the real friction usually happens after “Go-Live.” You will hear things like, “I can’t access that folder anymore,” or “The link I sent yesterday is broken.”

This happens because permissions work differently in Google and Microsoft. Although none is “better,” their underlying presumptions differ. This guide explains what changes, what usually breaks, and how your IT team can prevent chaos.

Why Permissions Change After Migration

Google Drive is built for speed. A user can share a single file with anyone in seconds, often ignoring folder structures. Links are the primary way people get work done.

SharePoint is built for structure. Access is based on sites, groups, and libraries. While you can share links, long-term security depends on a consistent “waterfall” structure.

The result of these different styles:

Permissions are rarely a “one-to-one” match.
Link behavior changes for external partners.
Unstructured sharing in Google often turns into a messy “broken inheritance” in SharePoint.

1. The Inheritance Waterfall

In Google Drive, you can share a file sitting inside a folder that nobody else can open. The share still works perfectly.

In SharePoint, the cleanest approach is inherited access. If you migrate a Drive environment full of “one-off” shares, you end up with “broken inheritance” everywhere. This makes SharePoint feel slow and hard to manage.

The Fix: Whenever possible, group your files by who needs to see them. It is much easier to manage access for a “Finance Site” than to manage 500 individual file permissions.

2. Shared Drives vs. My Drive

Shared Drives: These map well to SharePoint Sites because they are already owned by a team rather than a person.
My Drive: This content is user-owned. Many organizations migrate “My Drive” content to OneDrive first, then move team-related files into SharePoint later.

3. The Link Reality Check

Many organizations disable “Anonymous” links in Microsoft 365 for security. In Google, a link that worked for “anyone” might suddenly require a login or a 7-day expiration date in SharePoint.

The Fix: Communicate early. Tell your users that old Google links will not automatically redirect. They will need to generate new SharePoint links for high-use files.

4. External Sharing is More Formal

SharePoint external sharing is tied to guest identities. This is a massive security strength, but it requires a few more steps for the user. A common mistake is migrating first and discovering later that your security policies block essential workflows with contractors.

Real-World Scenarios

Scenario: Embedded Links. Links to Google files might be hidden in old emails or internal wikis. These will break.
Scenario: Messy Memberships. If a shared drive has people who shouldn’t have access anymore, migrating them creates a “security debt” in SharePoint. Copilot or Search will surface those old files to the wrong people very quickly.

Best Practices for IT Teams

Audit Before Moving: Identify folders with “unusual” sharing or external links that should be timed out.
Design the Target First: Don’t just dump files. Decide how many sites you need, who the owners are, and what the naming rules will be.
Set Sharing Policies Early: Decide now: Who can share externally? Do links expire in 30 days?
Run a Pilot: Migrate one small department first. Ask them what broke. It is usually links and expectations about “owning” a folder.

Frequently Asked Questions

Will my Google sharing links still work?

No. SharePoint generates entirely new links. You should plan a “Link Remediation” day to update important shared documents.

What is the best way to move Shared Drives?

Map them directly to a SharePoint Site or Document Library. Ensure the “Manager” in Google becomes the “Owner” in SharePoint.

Why do users lose access during the move?

Usually, it’s because the external sharing policies in your new Microsoft 365 tenant are more strict than your old Google settings.

Final Thoughts

Google Drive makes sharing quick. SharePoint makes security sustainable. The friction during a migration isn’t about the files—it’s about how people access them. If you plan your structure first, SharePoint becomes much easier to secure and manage over time.
