Informix 4GL migration to the NEW ERA environment

Dear Informix Developers, We've got lots of question regarding an easy path to migrate an old Informix-4GL application to Informix NewEra. We know that a form may be translated to a window using the Window Painter, but the only stated way to migrate the code is cutting and pasting it into the appropriate handler in the Window Painter. Even doing this, the application will not be capable of using the ODBC interface as it will not be using the connectivity class libraries. The question is: do you happen to know of any tool (developed by Informix or by any third party) that will translate an Informix-4GL application in a NewEra application translating the code to the right NewEra class, rather than using the old Informix-4GL statements ? Do you think this may be a good business area ? Thank you very much for your time and help. Yours sincerely, Roberto Panunzio
