 ### Run a migration job
 
+### [Azure portal](#tab/portal)
+
 1. Go to the **Migration Jobs** tab. The **Migration Jobs** tab shows all migration jobs you created in your Storage Mover resource, including the one you just created. It might take a moment for the new migration job to show up in the list. Refresh the page if needed.
