What are the attributes of a legacy system?

Legacy systems typically exhibit several key attributes, including outdated technology, which can make them difficult to maintain and integrate with modern systems. They often rely on older programming languages and hardware, leading to challenges in finding skilled personnel for support. Additionally, legacy systems may have limited functionality and flexibility, resulting in inefficiencies and hindering innovation within an organization. Despite these drawbacks, they often contain critical business data and processes that are essential for operations.
