Case Study: Large Financial Service Company achieves faster, lower-cost zSeries migration with OpenLegacy

Credit card provider cuts costs and development time with OpenLegacy

Large Financial Service Company, a credit card provider with a complex zSeries back office, needed to modernize a legacy Visual Basic front end that was no longer supported and could not meet new regulatory and security requirements. The company had repeatedly struggled to launch the migration because other vendors proposed solutions that were too expensive and would take years to deliver, so it turned to OpenLegacy and its zSuite platform.

OpenLegacy implemented an automated conversion path from the zSeries application to a responsive web application using Angular JS and REST APIs. A two-day proof of concept and a one-week pilot showed that roughly 70% of the migration could be automated, enabling a much faster, lower-cost, non-invasive transformation. The result is a full modernization program now underway, with the company expecting major cost savings, faster time to market, easier integration with internal systems, and improved compliance with security and regulatory standards.
