For business accounts, Google’s data import tool copies OneDrive files, folders and sharing permissions into each person’s My Drive, up to 500 users per import. Personal OneDrive accounts move by download and upload.
More than most expect: Google's data import copies files, folders and sharing permissions, but previous versions, Personal Vault files, Favorites and files created or last modified by external users stay behind.
Check storage before anything else, because Workspace Business Starter pools 30 GB per person against 1 TB per user on Microsoft 365 Business Basic, and Business Standard ($14) pools 2 TB per person. The detail I'd plan around is where files land: in each person's My Drive, not shared drives. Team files sitting in individual drives belong to individuals, so the day someone leaves, the company's work goes into offboarding limbo. Move shared work into shared drives right after the import and give each one an owner. Run a delta import to catch late changes, then cancel Microsoft at the end of its term.

Most buyers only budget for the new subscription. This estimates the hidden labor, data-cleanup, and retraining cost of actually making the switch.
Estimate assumes: 1 hour of data-mapping/cleaning labor per 2,000 records, a blended $75/hr ops rate, tiered migration & cleaning tooling fees, and 4 hours of retraining per seat at a $45/hr fully-loaded rate.
15 GB free against OneDrive’s 5 GB, shared with Gmail and Photos.
Google One Standard is $2.99 a month and can be shared with 5 others.
Docs, Sheets and Slides built in, and they open Office files.
For a business, check storage first: Workspace Business Starter pools 30 GB per person, against 1 TB per user on Microsoft 365 Business Basic; Business Standard ($14) pools 2 TB per person.
| Step | What you do |
|---|---|
| 1Set up Google Workspace (business) or Google One (personal) | Business: create a Workspace licence for each person you will import and turn on Google Drive for them. Personal: pick a Google One plan large enough for your OneDrive. |
| 2Connect OneDrive | Business: in the Admin console go to Data, Data import & export, Data import, choose Microsoft OneDrive and sign in as a Microsoft Global Administrator. |
| 3Upload the user list and identity map | Business: a CSV of OneDrive users to import, and a second CSV mapping each OneDrive email to its Workspace email. Optional filters exclude file types, large files or older files. |
| 4Start the import | Business: files and folders copy into each person’s My Drive in their original format; nothing is deleted from OneDrive. Run a delta import to catch late changes before you exit the import. |
| 5Personal accounts: download and upload | Sync or download your OneDrive folders to a computer, then upload them to Google Drive. |
| 6Re-share and cancel | Check that shared links work, then cancel the Microsoft plan at the end of its term. |
What this path doesn’t do for you:
Previous file versions, Personal Vault files, Favorites, folder colours and expiration dates do not import, nor do files created or last modified by external users. OneDrive files go to My Drive, not shared drives.

For business accounts, yes: the data import tool in the Google Admin console. It needs a Google super administrator and a Microsoft Global Administrator, and handles up to 500 users per default import.
Writer becomes Editor; Reader, Reviewer and Can’t download become Viewer. “Anyone” links become anyone-with-the-link sharing, and when an item has several links the most restrictive wins.
Not at the entry tier: 100 GB is $1.99 a month on both. For a business, both start at $7 a user, but Google pools 30 GB per person against Microsoft’s 1 TB.
Plan for the latest version only. Google’s OneDrive import copies only the latest version of each file; download-and-upload moves only current files too.
