ILM transition feature. This will allow transitioning of older objects to a different cluster or the public cloud by setting up transition rules in the bucket lifecycle configuration. This feature enables applications to optimize storage costs by moving less frequently accessed data to a cheaper storage without compromising accessibility of data.

To transition objects in a bucket to a destination bucket on a different cluster, applications need to specify a transition tier defined on MinIO...
