+# Upgrade from Azure Front Door Standard to Premium tier (Preview)
+
+Azure Front Door supports upgrading from Standard to Premium tier for more advanced capabilities and an increase in quota limits. The upgrade won't cause any downtime to your services or applications. For more information about the differences between Standard and Premium tier, see [Tier comparison](standard-premium/tier-comparison.md).
+
+This article will walk you through how to perform the tier upgrade on the configuration page of a Front Door Standard profile. Once upgraded, you'll be charge for the Azure Front Door Premium monthly base fee at an hourly rate.
+
+> [!IMPORTANT]
+> Downgrading from Premium to Standard tier is not supported.
+
+## Prerequisite
+
+Confirm you have an Azure Front Door Standard profile available in your subscription to upgrade.

+
+1. If you have WAF policies associated to the Front Door Standard profile, then you'll be taken to the *Upgrade WAF policies* page.

+
+    :::image type="content" source="./media/tier-upgrade/upgrade-in-progress.png" alt-text="Screenshot of the configuration page with upgrade in progress status.":::
