It’s tempting to dismiss legacy applications as dinosaurs–outdated and doomed to extinction, but don’t be too quick to write them off. Being a dinosaur is not bad at all.
Dinosaurs first appeared more than 230 million years ago and they dominated the earth for 135 million years. Not a bad run. Modern humans, on the other hand, have been around for less than 200,000 years. So don’t diss the dinosaurs. It’s the same with application software. Being old does not necessarily mean it’s outdated; it could just be that it’s working.
