Successful Go-live after Mainframe ADABAS/Natural core banking system conversion to Java

After a full-scale Mainframe ADABAS/Natural conversion project and final UAT our European customer has also completed the go-production phase with its converted core banking system in Java successfully. The conversion project results, and the go-live process has been approved by The Federal Financial Supervisory Authority (BaFin).

The legacy environment is a typical core banking system with various on-line applications for clerks, batch processing for scheduled maintenance of customers’ financial records in a highly secured environment, comprising 6 million LoC Natural sources, 650 ADABAS files, 7.000 JCLs and hundreds of batch schedules that all have been automatically converted to Java and Oracle on open system.

The client selected FreeSoft’s LiberatorWorkbenchTM technology after a comprehensive pilot phase for evaluating and comparing available ADABAS/Natural conversion technologies on the market.

During the project FreeSoft’s AppTesterTM was used for both batch and online tests to save time and costs. It is a must in conversion projects, where legacy results have to be compared to Java results in a “smart way”. Part of the project was also to help legacy developers’ transition to Java stack, IDE, and the open world, because their knowledge in the legacy business application is necessary for the converted system future maintenance and development (as usual) and cannot simply be substituted.
