Quick summary
You can replace a document in a SharePoint Document Library without breaking existing links by uploading a new file with the identical filename and clicking Replace. This method preserves the original SharePoint file URL so all shared links continue to work after the swap.
Steps
- In your SharePoint Document Library dashboard, go to the top menu bar and click Upload.
- Select Files from the dropdown, then choose the new document you want to upload — ensure its filename exactly matches the existing document you wish to replace.
- When prompted, tap Replace to confirm and proceed with overwriting the existing file.
- The document is now replaced and the original SharePoint file link remains intact and unbroken.
