What's inefficient about it? Computers are millions of times faster than they were, you're not worried about CPU cycles are you?

Is there a business need that the software can't meet? Or, is it just the general hassle of dealing with legacy code?

Not cpu cycles, I mean real system architecture inefficiencies + adding modern processes to improve performance. see my comment below on what I had in mind, but basically airline systems
