Pitney Bowes - VB6 to C# .NET Core on AWS

TSRI adapted its industry-leading modernization capabilities to the unique Pitney Bowes Visual Basic 6 (VB6) code constructs for a successful automatic modernization of over 443,000 lines of VB6 code and over 450,000 lines of XML meta-data to modern C# .NET Core coming in well within budget and completing the transformation earlier than scheduled.

Additionally, TSRI’s partner, Accenture, had the opportunity to manually rewrite the user interfaces for the application, to achieve a modern and user-friendly experience, while TSRI simultaneously completed the automated transformation of the application code and database written in VB6. As a result, the application achieved total functional equivalence while the look and feel of the front end was greatly improved.

Educational Testing Service (ETS) is the world's largest private educational testing and measurement organization. Each year, they develop, administer,  and score more than 50 million tests, including the TOEFL®, TOEIC®, GRE®, and Praxis® tests, in more than 180 countries. This requires an enormous data management capability. ETS turned to TSRI to transform their ECT and Praxis applications and databases from IBM job control language (JCL) and COBOL Batch to modern Java SE 17 in a cloud-native optimized AWS environment. To do this, they used a spring boot-type application to implement web services invoked by Python. TSRI also converted the IBM DB2 database and VSAM sequential database files to a relational PostgreSQL database on AWS Aurora.
