UK Visual Basic 6.0 Migration Case Studies – 800K LOC moved to C#


I have worked on and off with UK company Vertex for 13 years and like many large companies, some of their applications contain code that I first saw 13 years back – Visual Basic 6.0 code. Recently they managed to ensure compliance and business continuity by upgrading not one, but two of their mission-critical applications from Visual Basic 6.0  to .NET using a customized version of the Artinsoft Visual Basic Upgrade Companion (VBUC).

The stories behind both projects can be found at:
