Case Study: a BFSI client achieves 400% faster legacy application refactoring and testing with Sun Technologies’ IntelliSWAUT

BFSI Client cuts legacy testing time by 400% with Sun Technologies

A BFSI client sought to migrate components of a critical mainframe application to the cloud, requiring the refactoring of COBOL and PowerBuilder code into modern languages like Java. This mainframe modernization effort was challenged by intricate legacy architectures that made manual testing labor-intensive, error-prone, and unable to keep pace with frequent updates. Sun Technologies addressed this using their AI-powered testing tool, IntelliSWAUT, alongside AWS Blu Age.

The solution from Sun Technologies automated the conversion of legacy applications and integrated testing directly into the development cycle. This approach drastically reduced scripting time, automated complex migration processes, and ensured application integrity. The impact included refactoring and testing applications millions of lines of code long in just hours, cutting scripting time from six to two hours per test case, and successfully upgrading over 50 applications with minimal turnaround time and no errors.
