Originally developed by Denmark-based KMD in 2001 as a mainframe software application, the e-Boks system became more difficult and costly to maintain over time. The original platform also lacked the agility to expand to additional countries at scale and was not agile enough to expeditiously react to business changes. TSRI and KMD were able to modernize the e-Boks application from its original IBM PL/1 legacy code in a monolithic architecture to a modern, multi-tier application in a modern computing environment, running .NET, with no impact on the business and end-user experience. As a result, e-Boks has the potential to save more than 50-60 percent per year in operations and maintenance costs.

Deutsche Bank's relatively reliable mainframe infrastructure utilized COBOL and JCL languages running DB2 and VSAM flat-file databases for a variety of their key financial applications. The company’s leadership knew they would need to be cloud-enabled with a modern architecture to stay relevant for its customers and ongoing market needs. Following a successful proof of concept against other well-known industry soluitons, TSRI emerged as the best solution (highest quality output and most advanced architecture) for the full modernization effort of Deutsche Bank’s internal KreditManager application. An application which gives the company’s employees all of the tools they need to handle all of the company’s loan, credit and mortgage applications.

This case study documents technologies, processes, and methods of the timely and 100% automated conversion of a portion of the VHA (Veterans Health Administration) Information Systems and Technology Architecture (VistA) system, written in 2.1 million lines of MUMPS. The modernized module resulted in object-oriented and highly maintainable Java compatible with the J2EE framework. VistA is the core Electronic Healthcare Recordkeeping (EHR) system for the VHA hospital system, which provides EHR record keeping for more than 4.5 million veterans.

Using money from the Technology Modernization Fund (TMF) under the Modernizing Government Technology Act disbursed by the General Services Administration (GSA) of the U.S. government, the Department of Housing and Urban Development (HUD) sought to modernize several of its remaining critical systems on a legacy Unisys mainframe written in COBOL with a flat-file DMS-II database.

One huge benefit to an automated modernization is the migration from a monolithic architecture to a multi-tier architecture. The multi-tier, or layered, architecture separates the data layer from the logic layer, and also makes the presentation layer—what the end user sees and interacts with—independent of the other two. In this video segment, Scott Pickett discusses how this modern-day style of architecture allows developers to extend the functionality of an application without affecting the data or behavior of an application. Even more important, however, he explains how a modernized application can continue to refer back to legacy databases when organizations migrate to their target environment in smaller steps rather than committing all at once.
