I moved my tank with professional help. Wasn't expensive and well worth the money. Even if you get a bunch members to help you out, it is nice to have an experienced foreman.

When I moved my tank we kept the sand in place barely covered by water. Water and rock was added back carefully to minimize stirring. Didn't cause a cycle, but I did have another diatom bloom as well as some algae problems for a couple of weeks.
+1 My 30 gallon tank won't budge and its on carpet.
