Case Study: a leading freight operations company in North America modernizes a black-box mainframe with CAST Imaging

a leading freight operations company accelerates mainframe modernization in under a month with CAST

The customer, a leading freight operations company in North America, faced the challenge of modernizing a critical but monolithic mainframe application that had become a 'black-box' after three decades of development. This complex system, built with 11 million lines of code in Natural, Adabas, Cobol, and other languages, was difficult to decipher and modify. They enlisted a consultancy firm, which used CAST and its product CAST Imaging to reverse-engineer the application and build a business case for its digital transformation.

CAST Imaging was central to the solution, automatically reverse-engineering the core system to reveal its intricate interdependencies and schemas. This provided a comprehensive understanding of the application, which was essential for creating a secure multi-year modernization roadmap in under a month. The results included enhanced budget optimization, solid design rationales for the transformation program, and increased client confidence. The success led the client to adopt CAST Imaging for their wider modernization journey.
