Working with objects in a versioning-enabled bucket

Objects that are stored in an Amazon S3 bucket before you set the versioning state have a version ID of null. When you enable versioning, existing objects in your bucket do not change. What changes is how Amazon S3 handles the objects in future requests.

Transitioning object versions

You can define lifecycle configuration rules for objects that have a well-defined lifecycle to transition object versions to the S3 Glacier Flexible Retrieval storage class at a specific time in the object's lifetime. For more information, see Managing the lifecycle of objects.

The topics in this section explain various object operations in a versioning-enabled bucket. For more information about versioning, see Retaining multiple versions of objects with S3 Versioning.
