ING Bank

ING Bank Migrates IBM COBOL to Java for Cloud Deployment

ING Bank, a top European bank, used SoftwareMining for COBOL code refactoring and migration to Java. They initially considered outsourcing their mainframe modernization but chose to use SoftwareMining's COBOL to Java Refactoring Tool after thorough analysis. The project lasted 18 months, mainly for intensive testing. Over 2 billion transactions were compared between the original Mainframe and the new Java system.

Decommissioning the ING mainframe was challenging. With SoftwareMining's assistance, the project was successful. We've been running smoothly on Linux since Feb 2022.

Whirlpool Migrates COBOL Application to Java/Private Cloud

World-renowned household appliance manufacturer, Whirlpool, partnered with SoftwareMining as a part of a cost-cutting exercise. This move saw Whirlpool's batch COBOL application being translated to Java.

The main benefits included the ability to use the existing shared Unix servers to run the translated Java application. This move allowed for the decommissioning of the mainframe, thus reducing dependency on legacy languages and skill sets.

In total, SoftwareMining translated around 50,000 lines of JCL as part of the process.

Texas Department of Family and Protective Services

Texas DFPS Successfully Migrates Microfocus COBOL Application to Java

The Texas Department of Family and Protective Services collaborated with SoftwareMining for the translation of their COBOL application. This application interfaced with a regional database using Embedded SQL. Leveraging SoftwareMining's COBOL to Java Converter, the application was transitioned to Java. Testing and deployment were expertly managed by MCorp, a seasoned systems integrator with a niche in legacy modernization.

One notable challenge was the presence of intricate SQL statements in the system, which required conversion from COBOL to Java Dialect. Despite this complexity, the challenge was adeptly navigated, resulting in the system being translated and operational in a short span of six months.


CGI Seamlessly Migrates Financial COBOL Applications to Java with SoftwareMining's Translator

CGI, a leading IT firm, utilized SoftwareMining's Translator to successfully migrate three financial COBOL applications to Java. Post-migration, these applications were licensed and offered to CGI's extensive international clientele.

With this transition, CGI was empowered to offer their clients applications without any additional runtime costs. Additionally, they could easily integrate these applications with other systems and shift from indexed files to relational databases as needed. Moreover, the transition to Java unlocked access to a broader talent pool for application management and development.
