Modernizing UK bank’s legacy systems from IBM COBOL to Microfocus COBOL
Overview.
In the fast-evolving landscape of finance, adaptability is key. Recently, a prominent UK bank recognized the need to evolve. A company that serves a diverse customer base with an extensive range of products and services and their commitment to innovation led them to embark on this transformative journey. Their mission? To migrate their core banking platform from the traditional mainframe setup to the expansive realm of cloud computing. That is when the bank collaborated with Coforge to implement this migration seamlessly. This shift promised scalability, agility, and cost-effectiveness, but it also posed significant challenges.
