I have done this myself in the past. I try to keep everything from the original tank. When breaking down, leave the sand along with an inch or so of water covering the sand. Remove everything else to buckets, bins, etc. with lids for the move. After setting up the stand and tank in the new location (good advice about making sure you have everything needed for leveling the stand), remove whatever water is still in the tank. It will, or should be, pretty dirty from stirring up stuff during the move. I would leave all the original sand unless it's really nasty. Replace some of it with new aragonite sand if you think it's really necessary, add extra if you like, but I would keep at least 50% of the original sand. I would also add some rock since it doesn't appear that there is much in the existing system, and since you already have an established biosystem, I would probably add dry rock. No need to scrub, wash, or do anything beyond a simple rinse.
Then, definitely, scape it the way you want it and let it settle in. You may well have a low-grade cycle, but it should be short-lived and mild. Just monitor your ammonia and nitrites for a couple weeks or more. Be ready for water changes with new, good-quality saltwater. And definitely, be sure to have plenty of new water mixed and ready to go at the new location. You may not need it right away, but if you do, well, you get the idea, I'm sure.
Good luck with the move! Let us know how it goes.
