Infosys discusses how generative AI (GenAI) is transforming application modernization by automating tasks like requirement gathering, code generation, and template creation, thereby reducing effort and accelerating timelines. For example, one migration effort saw a ~15 % reduction in manual input; another achieved up to 50 % less manual effort and ~30 % faster delivery with ~85 % accuracy in code generation. GenAI is used to reverse-engineer legacy systems, extract business logic, generate microservices, migrate databases, and enable cloud-native platforms. The paper emphasizes that human review remains essential and that data silos and unsupported legacy languages still pose barriers to full automation.
