Billing Schedule

Hi
This is pretty basic and I am sure I know the answer but I am having a paranoid moment - if I inactivate a schedule in TR_BILLING_SCHEDULE, that will have no impact on existing orders with payment plans built using that schedule, right? Outstanding payments will continue to be processed normally using the pledge billing utility but no new orders with payment plans using that schedule will be created.
Thanks
