These parameters help optimize the migration for performance, compatibility, and diagnostics.

Data Pump can move data to the cloud by importing from a dump file stored in Oracle Cloud Infrastructure (OCI) Object Storage or directly from an Oracle Database using a database link. These methods allow for efficient data transfer to the cloud, with the dump file method providing a way to stage data in OCI Object Storage and the database link method enabling direct data transfer between databases.

When using the RMAN DUPLICATE command for database migration, the auxiliary instance must be started in NOMOUNT mode. This mode allows the auxiliary instance to be prepared for duplication without opening the database, ensuring that the data files are accessible and can be replicated to create a duplicate database.
