Autonomous Data Warehouse provides cloning where you can choose to clone either the full database or only the database metadata. You can also move an Autonomous Data Warehouse database to a different Oracle Cloud Infrastructure compartment.
When an upcoming release is available for preview with Autonomous Data Warehouse, you can clone your existing database to use the preview version.
Note:A preview version is only available when there is an upcoming major version to release. At times no preview version will be available.
