What is legacy software?
A legacy application is software where maintenance have not kept pace with the evolving needs of the business
Over time, business requirements, data volumes, and security demands grow, pushing existing systems to their limits as they strive to handle all business scenarios efficiently and securely. Business owners often face a critical decision: should they continuously improve their existing systems or replace outdated technologies with modern solutions?
Sometimes, this decision is made unconsciously due to a lack of understanding of the IT product lifecycle. By the time the need for replacement becomes clear, the system in question has likely become what is commonly referred to as legacy software.
