Microsoft is offering a promotional migration path for Microsoft® Visual Studio® .NET 2002 or Microsoft Visual Studio .NET 2003 licensed customers to migrate from Microsoft Visual Studio .NET to MSDN® Subscriptions.
The MSDN promotion will run April 5, 2004 until June 30, 2004 and will allow Visual Studio .NET customers to obtain the benefits of MSDN Subscriptions and Software Assurance at Software Assurance–only prices. During this promotional period, Visual Studio .NET customers may purchase MSDN Software Assurance–only SKUs in lieu of License & Software Assurance (L&SA) SKUs. If a customer purchases MSDN Software Assurance under this promotion, the customer will be granted with an underlying MSDN License and will be required to forfeit their corresponding licenses for Visual Studio .NET.
