For more information, see [ Aborting Incomplete Multipart Uploads Using a Bucket Lifecycle Configuration](https://docs.aws.amazon.com/AmazonS3/latest/dev/mpuoverview.html#mpu-abort-incomplete-mpu-lifecycle-config) in the *Amazon S3 User Guide*.

 ** NoncurrentVersionExpiration **   <a name="AmazonS3-Type-Rule-NoncurrentVersionExpiration"></a>
Specifies when noncurrent object versions expire. Upon expiration, Amazon S3 permanently deletes the noncurrent object versions.

Container for the transition rule that describes when noncurrent objects transition to the `STANDARD_IA`, `ONEZONE_IA`, `INTELLIGENT_TIERING`, `GLACIER_IR`, `GLACIER`, or `DEEP_ARCHIVE` storage class. If your bucket is versioning-enabled (or versioning is suspended), you can set this action to request that Amazon S3 transition noncurrent object versions to the `STANDARD_IA`, `ONEZONE_IA`, `INTELLIGENT_TIERING`, `GLACIER_IR`, `GLACIER`, or `DEEP_ARCHIVE` storage class at a specific period in the object's lifetime.  
Type: [NoncurrentVersionTransition](API_NoncurrentVersionTransition.md) data type
