legacy systems

Legacy systems refer to outdated computer systems or software that are still in use because they continue to perform essential functions for an organization. While these systems may have been cutting-edge in their time, they often lack modern features, can be difficult to maintain, and may not integrate well with newer technologies. Organizations face challenges when managing legacy systems, including increased costs, security vulnerabilities, and compatibility issues. Despite their drawbacks, replacing them can be complex and risky, as they often support critical operations, making the transition to newer systems a careful consideration.
