A legacy system is typically an older, outdated, or obsolete software or hardware application that is in use within an organization or company. It is often referred to as “legacy” because it no longer meets current technological standards or is no longer actively developed.The exact definition of a legacy system can vary depending on the context, but in general, a legacy system exhibits some common characteristics:

Age: A legacy system has typically been in use for a significant period of time and may have been developed many years ago. It may be based on outdated technologies or programming languages that are no longer widely used or supported.

Inefficiency: Legacy systems are often inefficient and may have performance issues. They may be unable to keep pace with the demands of a modern business, whether in terms of data processing speed, scalability, or user-friendliness.
