+# Upgrading Projects
+
+This article demonstrates how to use the [Telerik Visual Studio Extension]({% slug getting-started-vs-integration-overview %}) to upgrade a project that is pre-configured for the Progress® Telerik® UI for Blazor components.
+
+## Basics
+
+The **Upgrade Project Wizard** upgrades the version of existing Telerik UI for Blazor applications. To open the wizard, right-click on the **Project in the Solution Explorer -> Telerik UI for Blazor -> Upgrade Wizard**.
+

+
+## Files for Upgrade
+
+The **Upgrade Information** step of the Upgrade Project Wizard describes the files and assemblies that will be upgraded.
+
+![Upgrade Wizard Information Page](images/upgrade-wizard-information.png)
+
+The Telerik Blazor Upgrade Wizard will do the following: 
+
+* Update the version of the referenced Blazor NuGet package. It will also update the package source in the solution-based NuGet config file.
+* It will update the version of the theme references (If CDN is used, it will be also updated).
+* It will update all local script and style and NuGet package references in case client upgrades from Trial to Dev version.
+* It will add the new keys in the default (English) localization file.
+
+## Projects for Upgrade
+
+The next page of the Upgrade Wizard lists all projects from the solution that use Telerik UI for Blazor. Choose the projects that you want to upgrade and the version to which they will be upgraded.
+
+>tip We recommend selecting all projects that reference UI for Blazor and upgrading them to the same product version.
+

+
+## Upgrade Localization File
+
+If localization is enabled in the application, you can select the **Upgrade the localization file** option. The Upgrade Wizard will add new localization keys from the default (English) localization file that UI for Blazor distributes.
+
+The option is selected by default if there is a **Resources\TelerikMessages.resx** file in the current project. In this case, **Resources\TelerikMessages.resx** file is selected in the file browser.

+
+## Create Backup
+
+You can create a backup before running the upgrade wizard by selecting the **Create a backup before upgrading** option.
+
+>When the project and solution are placed in the same directory, the default backup location is set to the **%USERPROFILE%\Documents** folder.
+

+
+
+## Upgrade Log
+
+In case one of the options ([Create a backup before upgrading](#create-backup) or [Upgrade the localization file](#upgrade-localization-file)) is selected, an **Upgrade Log** will be opened in your default browser at the end of the upgrade. The log can show the backup location, an entry for each localization key added or a localization upgrade error. Each upgrade log file is in HTML format. The file name contains the date and time of the upgrade.
+

+
+## Troubleshooting
+
+The following common problems might occur when upgrading a project:
+
+* The [localization file is read-only or does not exists](#missing-localization-file).
+* The [**Finish** button is disabled](#finish-button-is-disabled).
+
+### Missing Localization file
+
+If the selected localization file in the pointed directory is missing or read-only, the page state is not valid. In this case, the **Finish** button will display a tooltip when clicked, indicating a page error.
+

+
+### Finish Button is Disabled
+
+If **Create a backup before upgrading** option is selected, and the **Backup location** is empty, the **Finish** button is disabled.
