TRANSITIONING LEGACY BANKING APPLICATIONS TO MODERN JAVA FRAMEWORKS

As financial institutions strive to remain competitive in an increasingly digital world, 
transitioning legacy banking applications to modern Java frameworks is no longer optional 
but essential. This paper explores the architectural strategies, tools, and methodologies 
involved in transforming legacy banking systems into cloud-native, scalable microservices
based applications. Drawing on real-world case studies, this paper examines the challenges 
faced during such transitions and the technical solutions implemented to modernize aging 
infrastructures, improve scalability, performance, and maintain security, compliance, and 
operational efficiency.
