The Code Conversion Utility removed events from the specified event case because this version of LabVIEW NXG does not support handling multiple events per event case.
Consider creating additional event cases for the events that were removed.
If the previous suggestions don't restore the functionality of the affected code and the code isn't essential to the core functionality of your application, you can remove the portion of code. If the code is part of the core functionality of the application, you can use the VI Interop node to call your existing code, provided that the new code organization meets the architectural goals of your application. If neither solution meets the requirements of your application, do not migrate to LabVIEW NXG at this time.
