Citations: URLs link to specific Oracle pages where possible. Some links (e.g., consulting services) are generalized due to broad applicability but remain authoritative.
Customization: The plan assumes a typical enterprise migration (e.g., 100 GB to 10 TB datasets). Adjust sub-tasks for larger datasets or specific tools as needed.
Duration: Timelines reflect Oracle’s recommended durations for small-to-medium migrations; larger projects may extend phases (e.g., Execution to 6-8 weeks for petabyte-scale data).
