What is AS400 modernization?

AS400 modernization refers to the process of updating and enhancing legacy IBM AS400 (now IBM i) systems to meet modern business needs. This can include migrating applications to newer platforms, integrating with cloud technologies, updating user interfaces, and improving overall system performance and security. The goal is to preserve valuable business logic while enabling the system to support current and future technology requirements. Modernization helps organizations reduce operational costs, increase agility, and leverage new digital opportunities without a complete system overhaul.
