Upgrade from Sitefinity CMS 9.1 to 9.2

If your project is running on Sitefinity CMS 9.1 and above, to upgrade it, perform the following:

1. Backup your project and its database.
2. Set the target framework version of your project to .NET Framework 4.8.
   Perform the following:
   1. Open your project in Visual Studio.
   2. In the context menu of SitefinityWebApp, click Properties.
   3. On Application tab, in Target framework dropdown box, select .NET Framework 4.8.
   4. Save the changes to your project
3. Reinstall all packages:
   1. In Visual Studio, navigate to Tools » NuGet Package Manager » Package Manager Console.
   2. Execute the following command: Update-Package -Reinstall

      NOTE: You do this, because changing the target framework requires re-installation of all packages.

4. In the Package Manager Console, install the latest Telerik.Sitefinity.All package using the following command:  Install-Package Telerik.Sitefinity.All
   

   NOTE: With this command you install the latest patch build, if you want to install a specific version you must use the command above followed by -Version and the version number.
   For example, enter Install-Package Telerik.Sitefinity.All -Version 13.0.7322.

   NOTE: The BCL dependency used by Sitefinity CMS to integrate Azure search in previous versions is also removed. As a result, you can safely remove the Tools folder under the root of your SitefinityWebApp project. 

5. In the Package Manager Console, uninstall the following packages and delete the respective assemblies from the project's bin folder:
   • Telerik.Sitefinity.Thunder
   • Telerik.Sitefinity.DropboxLibraries
   • Telerik.Sitefinity.MobileAppBuilder
   • Telerik.Sitefinity.DAM
   • Telerik.Sitefinity.EverliveConnector
   • Telerik.Sitefinity.OpenAccess

6. Build your solution.
