Case Study: a major North American food manufacturer modernizes warehouse management with Coherent Solutions’ AI-powered migration pipeline

a major North American food manufacturer migrates 3,100 PL/SQL routines in 3 weeks with Coherent Solutions

The customer, a major North American food manufacturer, faced the challenge of migrating its business-critical Oracle PL/SQL warehouse management system to Python. With 112 screens and approximately 3,100 routines, a manual rewrite was too slow and risky due to a shrinking pool of PL/SQL specialists. They partnered with Coherent Solutions for a legacy modernization and artificial intelligence solution.

Coherent Solutions implemented an AI-native migration pipeline where AI agents handled the initial code analysis and generation, while human engineers governed the process for accuracy. This approach delivered the first migrated screen, a shared technical foundation, and a fixed-price commitment for the remaining 112 screens in roughly three weeks. The solution translated 2,001 routines with 1,865 equivalence tests, ensuring the new system was maintainable, testable, and portable to the cloud.
