    An overview of what you will find throughout this guide.


    • An Umbraco 9 Cloud project running the latest version of Umbraco 9

    • At least 2 environments on your Cloud project.

    Step 2: Clone down your environment

    1. Clone down the Development environment.
    2. Build and run the project locally.
    3. Log in to the backoffice.
    4. Restore content from your Cloud enviroment.

    Step 3: Upgrade the project locally using Visual Studio

    1. Open your project in Visual Studio - use the csproj file in the /src/UmbracoProject folder.

    2. Right-click your project solution in the Solution Explorer.

    3. Select Properties.

      Solution Explorer

    4. Select .Net 6.0 from the Target Framework drop-down in the General section of the Application tab.

      Target Framework

    5. Go to Tools > NuGet Package Manager > Manage NuGet Packages for Solution....

    6. Navigate to the Browse tab.

    7. Install the latest stable version of the "Microsoft.Extensions.DependencyInjection.Abstractions".

    8. Navigate to the Installed tab.

    9. Choose Umbraco.Cms.

    10. Select your project.

    11. Choose 10.0.0 from the Version drop-down.

    12. Click Install to upgrade your project to version 10.

      Nuget Version Install

    Follow the steps 9-12 to update the following packages as well:

    Product Version
    Umbraco Deploy Cloud 10.0.0
    Umbraco Deploy Contrib 10.0.0
    Umbraco Forms 10.0.0
    Umbraco Deploy Forms 10.0.0
    Umbraco Cloud Identity 10.0.2
    Umbraco Cloud StorageProviders AzureBlob 10.0.0

    If you have more projects in your solution or other packages, make sure that these are also updated to support .NET 6 framework.

    With the packages and projects updated, it is time to make some changes to some of the default files.

    1. Update the Program class in the Program.cs file to the following:

      using Umbraco.Cms.Web.Common.Hosting;
      public class Program
              public static void Main(string[] args)
                  => CreateHostBuilder(args)
              public static IHostBuilder CreateHostBuilder(string[] args) =>
                      .ConfigureWebHostDefaults(webBuilder =>
    2. Re-enable the appsettings IntelliSense by updating your schema reference in the appsettings.json file from:

      "$schema": "./umbraco/config/appsettings-schema.json",


      "$schema": "./appsettings-schema.json",
    3. Follow step 2 for the following files as well:

    • appsettings.Development.json
    • appsettings.Production.json
    • appsettings.Staging.json

    The final thing you need to do before testing the upgrade locally, is to remove a series of files no longer needed in your project.

    Remove the following files and folders manually from your local project:

    • /wwwroot/umbraco
    • /umbraco/PartialViewMacros
    • /umbraco/UmbracoBackOffice
    • /umbraco/UmbracoInstall
    • /umbraco/UmbracoWebsite
    • /umbraco/config/lang
    • /App_Plugins/UmbracoForms

    Build and run your project locally to verify the Umbraco 10 upgrade.

    Step 4: Deploy and Test on Umbraco Cloud

    Once the Umbraco 10 project runs locally without any errors, the next step is to deploy and test on the Cloud Development environment.

    1. Remove the folders mentioned above on the Development environment using KUDU from the repository and wwwroot folders.
    2. Push the changes to the Development environment. See the Deploying from local to your environments article.
    3. Test everything on the Development environment.

    We highly recommend that you go through everything on your Development environment. This can help you identify any potential errors after the upgrade, and ensure that you are not deploying any issues on to your Live environment.

    Step 5: Going live

    Before deploying the upgrade to your Live environment, you will need to remove the folders you also removed from both your local instance and your Development environment.

    The files are:

    • /wwwroot/umbraco
    • /umbraco/PartialViewMacros
    • /umbraco/UmbracoBackOffice
    • /umbraco/UmbracoInstall
    • /umbraco/UmbracoWebsite
    • /umbraco/config/lang
    • /App_Plugins/UmbracoForms

    They need to be removed through KUDU from both the repository and wwwroot folders.
