Case Study: Activus

Situation

Founded in 1992 and headquartered in the UK, Activus is a leading worldwide supplier of application software and implementation services to the medical insurance, protection insurance and assistance markets. Their flagship product, Act-isureis a comprehensive processing platform for protection insurers, with installations in the UK, Ireland, USA, Middle East, Far East, China and Africa.

Used by insurers, managing agents, third party administrators and business process outsourcers in several countries, this software package integrates product, client, policy, claims, accounting and reporting modules, providing a lifetime view of all client information, transactions and correspondence, with full multi-country and multi-currency capabilities for both domestic and international operations.

Activus’ Act-isure is a client-server application. Technically it comprises 59 VB6 projects (885 total files and in excess of 550,000 code and design lines), It has a database layer, supporting both Oracle and SQL Server versions 7, 2000, 2005 and 2008.

A clean interface, sophisticated functionality and the possibility to create independent rules for each customer without programmer involvement are some of the most important features of this application, which make it very flexible and adaptable. However, Activus and its many customers determined that the application’s strategic direction required it to run on the .NET platform.

Solution

Due to time constraints and the value of the complex business logic embedded in the application, Activus didn’t favor a manual rewrite. After extensive market research they chose to engage with Mobilize.Net to assess the best option to move forward to migrate Act-isure.

After a thorough assessment performed by Mobilize.Net upon the application and Activus’ specific needs, it was decided to maintain the current application’s architecture and move the visual controls to .NET native controls. Additionally, coding patterns were consolidated, for example, by standardizing on Structured Error Handling (“Try..Catch”). An ADO to ADO.NET upgrade and the conversion of Modules to Static Classes were also contemplated as part of the solution.

Activus chose to migrate the system to VB.NET in-house, using Mobilize.Net’s Visual Basic Upgrade Companion and one Mobilize.Net migration architect to support the internal team. The target language was chosen mostly because the developers responsible for the maintenance and enhancement of the VB6 application were already familiar with VB.NET.

Benefits 

Using Mobilize.Net's tool considerably reduced the number of Errors Warnings and Issues; it was estimated that the Visual Basic Upgrade Companion produces 45% less EWIs than the Visual Studio Upgrade Wizard while migrating Act-Isure from VB6.0 to VB.NET. Translated in time to fix those issues, Activus will be able to cut down the migration time substantially from the original internal estimates

Functional Equivalence preserving all the business logic is the main goal of the migration project, but by moving Act-isure to the .NET platform Activus expects to ensure the future evolution of its business critical application, through a faster development environment.
