I don't have experience moving a tank that size, but I did recently move my 65g from Austin to Houston with no casualties. I individually bagged the fish and corals or used tupperware plastic containers to keep the SPS corals protected. I kept fish and corals in styrofoam boxes during transport. All of my rock was kept in rubbermaid totes or 5g buckets submerged in tank water as well as the sand.
I had fresh water on hand to make up a batch of new salt water to add to the tank when I arrived. I put all the sand, rock, and old water back into the tank, while I put the 4 fish into a 10g tank for a few hours while the dust storm settled in the main tank.
I didn't experience a cycle as everything and all corals and fish are doing very well 2 weeks after the move.
Of course, my scenario is scaled down from what you will have to do, but I feel the concepts are the same. And certainly get as many hands as you can to help move things.
Good luck with the move.
