-The Visual Studio extension [.NET Upgrade Assistant](https://marketplace.visualstudio.com/items?itemName=ms-dotnettools.upgradeassistant) can help upgrade ASP.NET Framework web apps to ASP.NET Core. For more information see the blog post [Upgrading your .NET projects with Visual Studio](https://devblogs.microsoft.com/dotnet/upgrade-assistant-now-in-visual-studio/).
+## Next Steps
 
-## System.Web Adapters
-
-The `Microsoft.AspNetCore.SystemWebAdapters` namespace is a collection of runtime helpers that facilitate using code written against `System.Web` while moving to ASP.NET Core. There are a few packages that may be used to use features from these adapters:
-
-* `Microsoft.AspNetCore.SystemWebAdapters`: This package is used in supporting libraries and provide the System.Web APIs you may have taken a dependency on, such as `HttpContext` and others. This package targets .NET Standard 2.0, .NET Framework 4.5+, and .NET 5+.
-* `Microsoft.AspNetCore.SystemWebAdapters.FrameworkServices`: This package only targets .NET Framework and is intended to provide services to ASP.NET Framework applications that may need to provide incremental migrations. This is generally not expected to be referenced from libraries, but rather from the applications themselves.
-* `Microsoft.AspNetCore.SystemWebAdapters.CoreServices`: This package only targets .NET 6+ and is intended to provide services to ASP.NET Core applications to configure behavior of `System.Web` APIs as well as opting into any behaviors for incremental migration. This is generally not expected to be referenced from libraries, but rather from the applications themselves.
-* `Microsoft.AspNetCore.SystemWebAdapters.Abstractions`: This package is a supporting package that provides abstractions for services used by both the ASP.NET Core and ASP.NET Framework application such as session state serialization.
-
-For examples of scenarios where this is useful, see [the adapters article](xref:migration/fx-to-core/systemweb-adapters).
+See the [Getting Started](~/migration/fx-to-core/inc/start.md) guide for how to update an existing application to take advantage of this pattern.
