Intelligent, Custom and Highly Automated Cross Platform Database and Application Migration

COBOL to .NET Conversion, United States

Customer

Our client was a major player in market-driven innovation and science. For more than two hundred years, it has been presenting world-class science and engineering to the global marketplace through innovative products, materials, and services. We worked with the client’s two biggest consulting divisions.

Challenge

Our client’s technical team was facing a challenging task of migrating one of their critical applications from COBOL to a modern and scalable .NET platform. C# was chosen as the target language. Comprehensive usage of a custom framework with a fast micro ORM PetaPoco and unique settings was an additional challenge.

Solution

After detailed testing and analysis of major migration vendors, Ispirer’s SQLWays was approved as the preferred tool for migration. The overall application modernization project was divided into two phases. The first one included an individual SQLWays tool customization based on our own code samples. Unique settings were specified by the Ispirer team during the product configuration period.

Results & Advantages

All customer requirements pertaining to the target code were successfully implemented by our developers. The team successfully accomplished this task within a short period of time and delivered the custom version of the migration product required for the second phase. The entire source code conversion was then performed by utilizing SQLWays and through continuous technical support from the Ispirer team. The core conversion phase continued for six months, during which more than a million lines of code were successfully migrated to .NET.

One of the major advantages of the proposed solution was the possibility of automating the migration process in order to minimize manual interventions as well as product customization efforts with each following database. Special customization was performed and the product showed 95–97% conversion rate after the initial run.

The client has recently contacted us again for an SQLWays license to execute a new project that involves migration of several hundred thousand lines of code.
