When migrating to MySQL HeatWave on Oracle Cloud Infrastructure (OCI), what is the recommended method...

Secure Transfer with OCI Data Transfer Service:

TheOCI Data Transfer Serviceis designed to securely transfer large datasets, including database backups, to the cloud. It involves:

Using physical storage appliancesto copy data locally and then shipping these devices to OCI data centers.

Data isencrypted and securely transported, minimizing the risks associated with online transfers.

This method is cost-effective and practical forterabytes or petabytes of data, avoiding bandwidth limitations and reducing transfer time.

Why the other options are incorrect:

A:FTP over the public internet is insecure and slow.

B:Physical hard drives without encryption and secure handling increase data breach risks.

D:SCP over VPN is secure but impractical for extremely large datasets.

E:Data Pump is useful for database-to-database transfers, not large file migrations.
