An existing system, usually a computer system, that must be accommodated in building new systems
When a new computer-based information system is developed, it may be necessary to retain hardware but more often software from the earlier system In these cases, the software that has been retained is referred to as a legacy system
An existing or inherited system used to run significant business functions that will be used as the base for conversion to or integration with a new system Legacy systems are typically replaced due to technical or functional obsolescence, or because the organization owning the system has been acquired
