Customer

One of the U.S.-based global leaders and innovators that provides integrated technology and services solutions for financial industry.

Challenge

The Customer decided to modernize its payment system by moving Informix 4GL reports to a .NET environment. It has become difficult to support and develop it, the low speed did not allow to work seamlessly. That’s why the management of the Customer initiated system’s consolidation to C# .NET desktop application. Ispirer was asked to handle this task.

Solution

After detailed analysis of the client’s requirements Ispirer team offered to start the migration project from the Extension Stage. The module which contained about 10 thousand lines of code was chosen for the conversion. While migrating it to C#.NET Ispirer technical team extended Ispirer MnMTK in accordance with conversion specifications.

The new conversion rules added into the Toolkit allowed to transfer dynamically forming Informix queries into stored procedures and SQL queries. Also Ispirer experts added the correct migration of several expressions and statements contained in the module. The accurate conversion of Informix 4gl reports into C# reports was significantly developed during the Extension Stage.

Results & Advantages

At the end of the Extension Stage due to the extended capacities the Toolkit could convert the module’s code with a high level of automation (~95-98%) and the need of manual efforts has almost disappeared. After such extension the Client focused on the migration of the remaining 200 000 lines of Informix 4GL code to C#.NET using the customized Toolkit.

Thus, the possibility to extend Ispirer MnMTK permits to reduce the number of post-migration interventions to zero. This approach provides substantial advantages in conversion quality, saving customer’s time and money.
