What is the Oracle recommended way to upgrade databases?

Answer options

• A. Command Line Upgrade
• B. Database Upgrade Assistant (DBUA)
• C. Data Pump Export/Import
• D. AutoUpgrade

Correct answer: D

Explanation

The correct answer is D, AutoUpgrade, which is Oracle's preferred tool for database upgrades due to its automation and ease of use. Options A and B are valid methods but are not recommended as the primary approach by Oracle. Option C, while useful for data migration, does not directly upgrade the database itself.
