+# Running the script using Cloud Shell
+
+Use the following steps to migrate your existing SQL Server - Azure Arc resources from Microsoft.AzureData namespace to Microsoft.AzureArcData namespace.
+
+1. Launch the [Cloud Shell](https://shell.azure.com/). For details, [read more about PowerShell in Cloud Shell](https://aka.ms/pscloudshell/docs).
+
+2. Upload the script to the shell using the following command:
+
+    ```console
+    curl https://raw.githubusercontent.com/microsoft/sql-server-samples/master/samples/manage/azure-arc-enabled-sql-server/migrate-to-azure-arc-data.ps1 -o migrate-to-azure-arc-data.ps1
+    ```
+3. Run the script.  
+
+    ```console
+   ./migrate-to-azure-arc-data.ps1
+    ```
+
+> [!NOTE]
+> - To paste the commands into the shell, use `Ctrl-Shift-V` on Windows or `Cmd-v` on MacOS.
+> - The script will be uploaded directly to the home folder associated with your Cloud Shell session.
+> - The script will prompt for the resource group name and print a message when migration is completed.
