Digital transformation has made it imperative for application leaders to find effective ways to modernize legacy systems. business fit, business value and agility. If the legacy application is not meeting the new requirements imposed by digital business, it needs to be modernized to fit properly, and should be upgraded to provide greater business value. Applications that lack the agility to keep pace with the demands of digital business may be a cost or risk liability.  

The process of legacy modernization is initiated when organizations find themselves stuck between maintaining older, expensive hardware that is unable to interoperate with new technologies, and undertaking the monumental task of revamping infrastructure to take advantage of a best-fit platform to support its business goals. This leads CIOs and IT leaders to balance a variety of factors to determine the time to modernization, where modernization delivers the most impact and how to properly plan the project to reduce business disruptions. The minimum goal of legacy system modernization is to achieve a like-to-like system parity with operational enhancements. The ideal goal is to achieve significant leaps in performance, agility and innovation.    Legacy modernization can range widely on the spectrum. One option may be to refactor code using migration tools to run the same system with minimal code changes on more modern infrastructure. In some cases, emulators are available that let you avoid code changes altogether. On the other end is completely re-architecting the system, replacing the legacy system with one built using cloud native development tools.
