In the face of the ongoing crises hitting the world’s major financial institutions, Citibank was looking for ways to reduce costs. In order to realize the desired savings, the bank chose to remain with their mainframe platform and migrate with Anubex via an automated software language translation from Natural to COBOL and CICS with DB2. 

The migration entails over 8 million lines of Natural code in production at various branches of the bank in 15 countries to Enterprise COBOL. The developers at the bank who maintained the Natural system now maintain the migrated code using leading, modern development tools like Eclipse.


A key parameter of this project was the aggressive timeframe in which the customer needed to go live and the use of migration tools, otherwise the bank would have to produce over 25.000 lines of fully tested, working code per day during a period of twelve months. Even with 150 programmers, such productivity is unheard of and having a tool to automate the conversion was the only way to make these spectacular savings in both time and cost possible.

The entire project took 20 months to complete with no more than 30 IT experts at both Anubex and the bank working together to bring the project to a successful conclusion. Using the tools and methods of Anubex, the bank realized significant cost savings and a ROI within less than 2 years after completing the migration.
