Legacy System Modernization

Summary: A major insurance company rearchitected its entire system that was written in legacy code.

The client decided to re-architect its major IT system that was written in legacy codes such as VB6 and COM+ technologies with a modern Service-oriented Architecture (SOA).  The customer decided to begin SOA adoption by developing reusable business services and making them available across the company over the Enterprise Service Bus (ESB). The client had already decided on the technology that they wanted to use for building the ESB and had already started an initiative to move all the existing services.

The results ended in increased productivity and cost savings and a Happy Client!

VLink was chosen as the consulting company to select a technology platform for SOA realization of legacy application modernization initiative


We reverse engineered all the COM+ services as there was no documentation available for the system. New services were developed in WCF .Net service based on the reverse engineered logic.


The client was enabled to make the correct decision and implement cost-effective solutions for the SOA infrastructure. • Developer productivity was enhanced and cost savings were realized due to the methodology we implemented.
