When you PUT an object in a versioning-enabled bucket, the noncurrent version is not overwritten. The following figure shows that when a new version of `spark.csv` is PUT into a bucket that already contains an object with the same name, the original object (ID = `ede336f2`) remains in the bucket, MinIO generates a new version (ID = `fae684da`), and adds the newer version to the bucket.

		# Get the presigned URL to fetch the requested
		# original object from MinIO
		s3_url = object_context["inputS3Url"]

		# Extract the route and request token from the input context
		request_route = object_context["outputRoute"]
		request_token = object_context["outputToken"]

		# Get the original S3 object using the presigned URL
		r = requests.get(s3_url)
		original_object = r.content.decode('utf-8')

> **NOTE:** **Each pool you add must have the same erasure coding parity configuration as the original pool, so the same data redundancy SLA is maintained.**

## 3. Test your setup

To test this setup, access the MinIO server via browser or [`mc`](https://min.io/docs/minio/linux/reference/minio-mc.html#quickstart).
