Although 'migrate_set_downtime' has been deprecated and replaced with 'migrate_set_parameter downtime_limit', it has not been completely eliminated, possibly due to compatibility with older versions. I think as long as this old parameter is running, we should report appropriate message when something goes wrong, not be silent.
