 > [!NOTE]
 > If you're planning to upgrade your Windows operating system, Azure Migrate and Modernize might download the Windows SetupDiag utility for error details in case upgrade fails. Ensure that the VM created in Azure after the migration has access to [SetupDiag](https://go.microsoft.com/fwlink/?linkid=870142). If there's no access to SetupDiag, you might not be able to get detailed OS upgrade failure error codes but the upgrade can still proceed.
