Legacy Migration - VB Migration or VB Conversion

A VB Migration process especially for migrating to .NET Framework platform is normally very slow & expensive. And that kind of VB Conversion process requires a deep knowledge in all the subtleties of both VB6 and VB.NET languages. But presently many custom software development companies provides an innovative state of the art tools and services which assists in efficiently transforming any of your legacy applications which are coded in Visual Basic to a Web enabled application. Coz of this, you will be efficiently and cost-effectively adapting your IT systems to a changing business environment.

Legacy Migration of any Visual Basic 6.0 application to Visual Basic .NET requires the following major steps: Perform an application assessment based on project selection guidelines, Perform changes based on pre-migration recommendations, With the help of the upgrade wizard, upgrade the Visual Basic 6.0 application to Visual Basic .NET, Perform changes based on post-migration recommendations.

By converting your applications from
Visual Basic 6.0 to .NET framework, saves you money and lets you leverage the many new capabilities of .NET framework, such as XML and Web Services. There are many automated tools that are specially designed to optimize the visual basic to .net migration process. It will significantly reduce your VB migration costs, time, and risks by using powerful VB to .NET upgrade tools and established best practices.

There are two strategies called Migration Wizard and Fresh Design through which you can
migrate from VB to VB.NET. In .NET Framework IDE, Visual Studio.NET, you can find a Visual Basic Upgrade Wizard that helps migrate your Visual Basic application to VB.NET. But through this wizard you cannot upgrade all the VB to VB.NET. You have to manually make some modifications. This wizard produces a report in HTML format suggesting the places where it failed to modify the VB to VB.NET. You have to redesign certain core blocks or modules of the application or redesign the entire application to shift to VB.NET. Though you can reuse existing components, because managed code run in tandem with unmanaged code, you have to rework on design, code, and deployment of the application before migrating to VB.NET.
