Legacy Systems

Legacy systems are software applications or IT systems that are outdated or obsolete but are still in use for various reasons, such as business criticality, regulatory requirements, or lack of resources to replace them. These systems often pose challenges for organizations due to their limited functionality, security vulnerabilities, and high maintenance costs. Understanding legacy systems is crucial for professionals in IT, software development, and business analysis.
