You know what I think about legacy computer systems? Legacy systems are always on the chopping block because there is a seemingly never-ending cascade of new technology designed to make business more profitable and our lives easier. Moore’s Law would suggest that IT used to build systems today is superior to yesterday’s technology. However, new is not always better. Certainly, today’s IT is smaller and faster, but that doesn’t necessarily make it superior to the technology used in legacy systems. In fact, implementing new IT systems carry inherent risks that may outweigh the drawbacks of modifying or converting existing systems.
