Interview: Is there an easier way to refactor applications? | Computer Weekly
Briefly

Java migration often relies on outdated strategies that are unsustainable for organizations. For instance, a bank struggling to upgrade from Java 8 due to constraints from WebSphere highlights the challenges faced. Modernizing applications without breaking them is tough, especially when dealing with thousands of legacy systems. A report from Forrester emphasizes that maintaining this technical debt raises costs and risks, urging companies to consider outsourcing to experts. This can improve operational reliability and facilitate the transition towards modern AI-driven architectures while alleviating resource strain.
