Legacy System Definition & Why do we need to archive legacy systems?

Jim Bob04 Jun, 2022Technology

A legacy system means an outdated computer software/application, equipment/hardware, or technology still used in daily operations. The system still fulfils the requirements for which it was initially designed for, but that system has no longer support and maintenance and is also restricted in terms of development. However, they can not conveniently be replaced. For example, Windows XP, Windows Vista & Windows 7 are legacy operating systems after Microsoft has stopped security & other updates and assistance for it. More than 2 million devices are still running on this operating system.
