Legacy System | Legacy
Legacy system is a term that refers to an old or obsolete computer system, software program, or technology that is still in use because it is still necessary for some essential business or administrative function, but which is difficult to maintain, or update, because of its age or lack of compatibility with newer systems.

These systems are often characterized by their complexity, inflexibility, and lack of support or documentation. In many cases, legacy systems have been in use for many years and may have been developed using outdated technologies and programming languages, making them difficult to maintain or modify.

Despite these challenges, many organizations continue to rely on legacy systems as they provide critical data and functionality, and may need to invest in dedicated resources and expertise to keep them running smoothly.

BITS experts have worked with legacy systems in a variety of projects. A selection of case studies and references can be found below.
