Legacy applications contain the time-tested business knowledge, distilled over a long period of time. How best to evolve or reuse these legacy IT Assets, under changing business, economic and IT environments, is a challenge that every mainframe enterprise has to address. Many have tried solving the aging legacy applications by rewriting it in new technology, most have failed to eliminate the legacy. Not because of the technical feasibility of such rewrite, but due to the time, effort and risk associated with these approaches.
Legacy Modernization enables you to preserve these proven legacy IT assets and still evolve and effectively transform them to address the changing business needs “economically”.
While many legacy modernization solutions are available in market, mainframe enterprises adopt a screen-based modernization approach because it’s relatively inexpensive and time-to-market is typically short.
One such simple yet powerful screen-based legacy modernization solution for rapid transformation is Host Access Transformation Services (HATS).
HATS, a proven offering with a wide range of capabilities and deployment options, help you realize new value from your feature-rich, mission-critical legacy applications.
Without making any changes to your existing legacy application, or even requiring access to source code or screen maps, HATS can transform and extend your green screen System z and IBM i application to intuitive web, portlet, rich client or mobile device user interfaces.
