One thing I wish all the manufacturers of those type of cabinets would do is put pockets in the bottom for 2x4s all the way through where the levelers are, that would not interfere with the levelers bolts. then it would be easy enough to stick a 2x4 on both ends to prevent the unit from tipping over while moving, and thus avoiding the heartache. Not doable on the old cast iron, but certainly doable on those sheet metal cabinets. Just make the pocket some tubing and everyone can benefit by having their machines safe during a move.
