# Fix Fiori Elements Extensions

> | Handle Fiori Elements V2 controller extensions during UI5 modernization. Use this skill when: - Extension controllers use sap.ui.controller() AND the manifest has a matching controllerName entry (Case B → report only, do not modernize) - Extension controllers use Controller.extend() with manifest controllerName registration (Case B → report only, do not modernize) - Code contains registerControllerExtensions calls (Case A → ControllerExtension.extend + override) - Manifest.json has sap.ui5/extends/extensions/sap.ui.controllerExtensions with controllerName entries Case B (plain object) is by far the most common. For Case B, do NOT modify controller files — report them and move on. Case A requires actual code modernization. For plain controller definitions in custom (non-Fiori-Elements) apps where sap.ui.controller() is just defining a standalone controller, use fix-js-globals (Case 9) instead.
