About Migrating ASP.NET-based Commerce Server 2002 Applications to Commerce Server 2007
If your Commerce Server site is based on the Commerce Server 2002 SDK sample, or if you created your own ASP.NET-based site by using Commerce Server 2002, your site migration plan must include upgrading to Microsoft Visual Studio 2005 or Visual Studio 2008, running the Upgrade Wizard to migrate the site data, and making API changes to your site code to account for changes that were made to Commerce Server.
If your site is based on the Retail2002 Solution Site, we recommend that you re-develop your site based on the Starter Site.
The Commerce Server developer platform integrated into Visual Studio 2003 has been improved and is now integrated into Visual Studio 2005 and Visual Studio 2008. Visual Studio 2005 and 2008 use the Microsoft .NET Framework.
