If you go to use Arm Navigation in your project, you need to configure the arm menu in the Model Editor.
See the documentation Alternative Navigation Items
If you want to copy Navigation Items from DevExpress navigation to arm navigation, copying the navigation in the controller is not suitable for you (when you use arm navigation, the DevExpress NavigationController is not activated).
Perhaps you can copy the navigation using the model updater. See Extend and Customize the Application Model in Code
