+## Description
+
+This tutorial explains in detail how to upgrade your Telerik [Trial]({%slug telerikreporting/licensing%}) to a Licensed version of [Telerik Reporting](https://www.telerik.com/account/product-download?product=REPORTING).
+
+Let's start with having a trial version installed on your machine and a project that uses the trial version. Access to the Trial version of product files in the Downloads section of your Telerik account: 
+
+![Downloads Trial](images/downloads-section-trial-license.png)  
+
+The difference between the developer and trial versions of the assemblies/ NuGet packages is that the trial version adds a copyright message to the produced reports:

 ## Solution
 
-After purchasing the Developer license, you need to download the Telerik Reporting DEV installer from your [Telerik account -> Downloads](https://www.telerik.com/account/product-download?product=REPORTING). Refer to the Documentation article - [How to download Telerik Reporting installer]({%slug telerikreporting/installation%}#msi-installation) for instructions. Select `Purchase` from the `Licence` dropdown menu and you will be able to download the developers `.msi` file.
+Once you purchase a Telerik license, you will have access to the **Purchase License** Type in your Telerik account:
 
-The installer will replace the trial version with the developer's one.

+
+## Upgrade the Trial Assemblies
+
+1. Download the DEV .msi file for the Purchase version: [How to download Telerik Reporting installer]({%slug telerikreporting/installation%}#msi-installation).
+1. Uninstall the already installed Trial version, e.g. from the Windows Control Panel >> Programs and Features.
+1. Install the downloaded .msi file in step 1.
+1. Update the references in your project with the assemblies from the licensed installation. It is necessary to delete the old trial assemblies first:
+
+	![Remove Assembly](images/remove-assembly.png)   
+
+1. Then, add the licensed ones:
+
+	![Add Assembly](images/add-assembly.png)    
+
+	Right-clicking on the assembly to show its Properties allows you to check if it is a **TRIAL** assembly:

+	![Trial Assembly](images/trial-assembly.png)    
+
+1. Rebuild your project, close Visual Studio, and open it again to make sure that no references are kept in the memory by Visual Studio.

+
+## Upgrade the Trial NuGet packages
+
+1. Open the **NuGet Package Manager**, e.g. select the Manage NuGet Packages... option
+
+	![Open NuGet Package Manager](images/open-nuget-package-manager.png) 
+
+1. Uninstall any Trial Telerik NuGet packages:
+
+	![Uninstall Trial Package](images/uninstall-trial-package.png) 
+
+1. Install the respective Purchase version of the NuGet packages, without the word "Trial" in its name:
