Heres how I've moved large tanks.
Live Rock into tubs. Throwing newspaper soaked, over top. Saving some water from the tank in 5g buckets, throwing it on the rock from time to time, to keep it from drying out. Next bes thing would be to put it all in totes, on wheels with saltwater in it.
Sand has got to come out. Throw it in 5g buckets, to be rinsed out really well before adding it back to the tank. This is crucial, as this is the stuff that can ruin your day when setting it all back up, throwing your tank into a cycle, and the nasty crap it will release.
Have the appropriate amount of water already made ahead of time, and to temp
Fish in totes.
Corals in totes.
Set tank in new spot
Throw in your cleaned out sand bed.
Throw your hose in, and pump in the new water, only half way.
Get your LR in place, if you need more water, then by all means add a bit more.
Get the LR set in place, set up powereads, throw in the fish. Place corals. Set up lighting, and skimmer.
