Misconceptions regarding liposuction techniques

All liposuction techniques require moving a metal cannula under the skin with vacuum aspiration. At a minimum, this is called Traditional Liposuction. All of the other techniques you mentioned add the delivery of some type of energy below the skin surface (ultrasound - VASER or light SmartLipo & CoolLipo). Since these have something "more" added than traditional liposuction, they are actually more invasive. It is a marketing ruse that they are considered less invasive. As these techniques damage the fat cells (lasers burn the fat, ultrasound breaks the cells open), they cannot be used for harvesting fat that you plan to transfer to another location. If you did try to do this, you would be injecting oil that will certainly get resorbed.
