Lifecycle transition functionality provided in [bucket lifecycle guide](https://github.com/minio/minio/master/docs/bucket/lifecycle/README.md) allows tiering of content from MinIO object store to public clouds or other MinIO clusters.

Transition tiers can be added to MinIO using `mc admin tier add` command to associate a `gcs`, `s3` or `azure` bucket or prefix path on a bucket to the tier name.
