When upgrading FDI to the latest application update, how are customizations affected?

• A. All customizations are fully preserved with no review.
• B. Updates are upward-compatible unless otherwise documented; you should review customizations after each update.
• C. Customizations are automatically removed during the upgrade.
• D. Only non-critical customizations are retained.

Answer: (B)

Upgrades are designed to be upward-compatible with existing customizations, but you still must verify them after applying an update. When a new application update is released, Oracle documents any changes, deprecations, or potential impact on customization points such as APIs, data structures, or UI behavior. Because those changes can alter how a customization runs or interacts with the system, a post-upgrade review and testing step is essential to catch any issues and adjust accordingly. This approach ensures you preserve functionality while adapting to new features or revised behavior in the latest version. It’s not safe to assume all customizations survive without review, nor to expect automatic removal or selective retention of only non-critical ones.
