##
# @migrate_set_downtime:
#
# Set maximum tolerated downtime for migration.
#
# @value: maximum downtime in seconds
#
# Returns: nothing on success
#
# Notes: This command is deprecated in favor of 'migrate-set-parameters'
#
# Since: 0.14.0
#
# Example:
#
# -> { "execute": "migrate_set_downtime", "arguments": { "value": 0.1 } }
# <- { "return": {} }
#
##
{ 'command': 'migrate_set_downtime', 'data': {'value': 'number'} }
