Which statement accurately describes upgrade behavior for FDI customizations?

• A. Updates always preserve all customizations without review.
• B. Updates are upward-compatible unless otherwise documented; you should review your customizations after each update.
• C. Customizations are reset to defaults after an update.
• D. Only new features are preserved; existing customizations are discarded.

Answer: (B)

Upgrades aim to be upward-compatible, so existing customizations should continue to work in a newer release. But this isn’t a guarantee that everything stays perfectly intact without checking. Release notes and documentation may call out changes that affect customization points—such as updated APIs, configuration options, or UI behavior. Because of that, after applying an update you should review and test your customizations in a staging or test environment, verify they still behave as intended, and adjust scripts, configurations, or styling as needed. This approach lets you take advantage of new features while catching any issues early. The other statements aren’t accurate because updates aren’t guaranteed to preserve all customizations without any review, they don’t reset all settings to defaults, and they don’t discard existing customizations unless explicitly stated.
