+## Limitations
+
+- SKUs aren't mutable. You can't change the SKU of an existing resource.
+- A standalone virtual machine resource, availability set resource, or virtual machine scale set resource can reference one SKU, never both.
+- [Move subscription operations](../azure-resource-manager/management/move-resource-group-and-subscription.md) aren't supported for Standard Load Balancer and Standard Public IP resources.

 ## Next steps
 
 - See [Create a public Standard Load Balancer](quickstart-load-balancer-standard-public-portal.md) to get started with using a Load Balancer.
