Dictionary
Definition: legacy application
An application that was written for an earlier operating system or hardware platform. For example, mainframe applications were legacy apps when the world embraced client/server networks. Windows 3.1 applications were legacy apps when Windows 95 was introduced. Any business software that is not Internet enabled in some form is often considered a legacy application.
They Hang Around
Although many are eager to embrace the newest and latest, there is an investment in older software, which is sometimes substantial. Legacy applications tend to remain in use far longer than anyone predicts. In some cases, they thrive, such as mainframe applications. Even DOS and Windows 3.1 applications are running under Windows Vista and Windows 7. See legacy system.
