By default, when you upload the file with same name. It will overwrite the existing file. In case you want to have the previous file available, you need to enable versioning in the bucket.
1 Answer. To replace an old file in S3 bucket with a new file, you can just upload your new file on top of your old file. Your new file will overwrite the existing one.
If you send the file to the existing key, it will overwrite that file once the upload is complete.
You can use S3 Versioning to keep multiple versions of an object in one bucket and enable you to restore objects that are accidentally deleted or overwritten. For example, if you delete an object, instead of removing it permanently, Amazon S3 inserts a delete marker, which becomes the current object version.
