Why is legacy decommissioning so important? Because keeping legacy systems alive means high costs for IT to cover maintenance of hardware and software. With aging hardware and software, the 'know-how' for using the systems diminishes quickly and often only a few people within an organization retain specific knowledge around the systems.
As regulated industry implements updated, more compliant solutions for their enterprise needs - legacy systems must be retired or removed from service. Many of these legacy systems contain critical data to meet regulatory requirements. What happens to the data stored in those legacy systems? Decisions must be made as to what data to migrate into the new system. What happens to the remaining data? Where is it stored or archived? How long should the data be stored?
