After versioning is enabled for a bucket, you can extend the retention period of a WORM-protected object version, as well as delete, share, and download object versions.
If the version you want to download is in the Cold storage class, restore it first.
In a WORM-enabled bucket, if an object has no retention policy configured or its retention policy has expired, you can delete a desired object version on the object list page. If the object version is within the retention period, it cannot be deleted.
