IBM has maintained compatibility between mainframe generations. I have not looked into this but assume the application is running on modern systems.
If that is the case and it works and there's sufficient performance, why not? Why reinvent the wheel? The biggest issue might be the language used to program it. There are still uses for FORTRAN and COBOL. It's not all Java, C#, etc.
