Transferring 55 gallon to 100 Gallon

Hi, I am moving over my current basic reef system to a new Aqua Medic Percula Bow front, it's roughly 4x2x2. The old oner is 48"x15"x". My question is, can I fill the new tank half way with newly made water, then add all the water from the old tank, along with the rock and sand etc? Would this just be like doing a large water change or will I run into problems? I wont be moving any corals, just a few mushrooms and Zoa. There are also currently only 3 fish in there, a small Boxfish, small Procupine Puffer and a very small Regal Tang. This is not their tank in the long run dont worry, I am setting up a FOWLR bigger than #both these for the Porcupine and Boxfish to go in, possibly even the Tang.

If you dont think this is a good idea is it just a case of recycling a new tank and waiting until it's ok to add the fish?

You can certainly do it the way you describe, but I would first cycle the additional rock you will need for the new set-up, then add the old and new rock to your new tank.
