legacy data

Legacy data refers to information stored in older systems or formats that are still in use but may no longer be current or efficient. It often exists because organizations haven't yet migrated to newer platforms or because the data is critical and must be preserved. Despite its age, legacy data can be valuable for historical reference or ongoing operations. However, managing it can pose challenges due to compatibility issues and limited support for older technologies. In essence, legacy data is past information that continues to play a role in an organization's current activities.
