I agree,
I'll also say. if you want to speed up the cycle of the new tank use some of the old. First setup the 55 the way you want it, but leave some space from the top so you can add more. Once you have it ready take some water from your 10g tank and add it as well as some substrate, sand crushed coral etc...
If you have floss filter media in the 10g replace it with new and put the old in the 55. This will help introduce the bacteria you need in the tank.
those are my suggestions, I hope they help.
