If disk_size parameter is set the disk size will be fixed for this VPS. That means that consequent upgrade/downgrade function call without this parameter will not change disk size of the VPS. The disk size of VPS cannot be lowered. To downgrade VPS plan the VPS disk size must be lower or equal to the disk size of target VPS plan.
