Case Study: ista International achieves 100% automated legacy migration with PASS Consulting Group

ista International achieves 100% automated COBOL-to-Java migration with PASS Consulting Group

ista International, a global service provider for energy efficiency in buildings, faced challenges with its legacy COBOL-based accounting system, which was difficult to maintain and limited operational flexibility. To ensure future viability, they partnered with PASS Consulting Group to explore an automated migration of the system to a modern Java and web architecture using the vendor's Migration Factory service.

In a successful Proof of Concept, PASS Consulting Group implemented a 100% automated migration process, using robots to analyze and transform the code without manual intervention. The resulting Java-based prototype was functional, maintainable, and met all performance expectations, proving the feasibility of the approach and paving the way for reduced operating costs and increased development flexibility.
