The action to perform. Valid value:


RegionId String Yes

The available specification varies by regions. For more information, see Guaranteed-performance instances.

Note: When you change a shared-performance instance to a guaranteed-performance instance, a brief disconnection of service may occur for 10 to 30 seconds. We recommend that you perform this operation when the service is not busy or after the service migrates to another SLB instance.
