You can do a "search" on moving tanks...theres a bunch of info on moving 10', 10 miles, and 10 hrs...
But basically if you get a couple of 30 gal Rubber Maid "trash cans" (new/clean) and put 20 gals water your fish a heater and a powerhead in one...then the rest of the water, and rock in the other..and the sand in a couple 5 gal buckets....
Then move to your new location plug in the heater and powerhead...set up the tank add sand...put a plastic garbage bag over the sand, add water slowly to not disturb the sand too much... remove the bag, add rock and let settle for a bit then add rest of water and the fish...
