Are you starting a new sandbed for the 120? IF so, I think the safest option is to have the 120 up and running beforehand, using some of the water from the 55, as you would take out in a large water change. Do that a couple of times, and make the rest of the SW fresh as Steve says. If it takes several days to get the new tank topped right up, no biggie.

The beauty of having the new system up and running is you have room for error. If one tank goes south somehow during the move, then you have a safe haven - if the move goes sour and only one tank is viable, then where do you go?

Move over some of your rock, add some of the new rock you'll need - - and let the 120 get on its feet for a couple/few weeks before moving your babies. This is the method I've had best success with the lst 2 tanks. They cycled quickly and became surprisingly stable faster than any other moves.

Just check your levels diligently and keep in mind it might take a month before you are safe to go over. Not a problem for a conscientous marine aquarist.
