Mainframe COBOL App Modernization & Migration – NxTran

The evolution of web technologies in the recent years makes a compulsive reason for companies to consider migrating legacy mainframe COBOL applications to modern technologies like Java or .NET.

Kumaran Systems has developed an effective and comprehensive Mainframe Legacy -to-JEE/.NET modernization practice. The modernization is powered by an internally developed re-engineering workbench NxTran. The Workbench is a collection of tools, each focus on specific source technology (BMS, COBOL and JCL) and convert them to JEE or .NET. It is an effective and comprehensive workbench, which helps to highly automate entire migration process.

Here are some of the salient features of NxTran:

  • Perform Mainframe Code Analysis and generates inventory of the application
  • Convert BMS User Interface to HTML5, CSS3, Angular JS.
  • Convert COBOL Business Logic to Java.
  • Convert Batch Logic to Spring Batch.
  • Convert COBOL Stored Procedure to DB2 Native SQL.


Business challenge
  • Mobile ready Rich responsive web user interface.
  • Cross browser support
  • Eliminates dependency of legacy technologies & components
  • Eliminate legacy skill set dependency
  • Open standards
  • Enhanced support for the application
  • Rich user experience (UX)
  • Easy integration with other systems
  • High scalability even using commodity servers


Business Benefits
  • Lower Total Cost of Ownership (TCO) - The cost of a migration is much less when compared to redevelopment.
  • Overall reduction in Mainframe Modernization Schedule.
  • Workbench-based automatic migration, as opposed to rewriting, reduces development time because it involves moving to a new system based on business logic, requirements, and functionality that is already well defined.
  • Functional testing efforts are reduced to a great extent as the code is generated automatically based on the original source code.
  • Automatic migration makes for a relatively low-risk development project because of the reduction in time.
  • Rich & Responsive user interface which is an additional business value.
  • Increased level of customization and code maintainability in JEE or .Net development standards.

Kumaran’s Mainframe Legacy-To-JEE Migration Practices

Beyond the automation, our consultants optimize the code as well. This helps create an application exactly as per the client requirements the first time over, reducing iterative development, risk of bugs is also mitigated and the application remains light and highly portable, robust and scalable across the application servers.
