In general there is no real reason why a software running on Windows 3.11 could not contain 100 years of development time. What seems less likely is that the majority of that code would be highly hardware or system specific and would require porting to a modern platform. But as we do not really have any idea what kind of system we are talking about, it is hard to speculate.
