Updates a managed instance group using the information that you specify in the request . This operation is marked as DONE when the group is patched even if the instances in the group are still in the process of being patched . You must separately verify the status of the individual instances with the listmanagedinstances method . This method supports PATCH semantics and uses the JSON merge patch format and processing rules .
