Upgrading from 55 to 75 help

I have a 55 gallon reef right now and I will be upgrading to a 75 reef ready. I will be ordering some new equipment for the upgrade but I will also be using some of my old equipment. I want to use the live sand and rock I already have in the 75 plus get some more. So I was wondering what are some ways of making the transfer to the new tank while still giving the new tank some time to cycle. I have 60 lbs of sand and about 60 lbs of lr right now. For inhabitance I have a maroon clown, LTA, yellow flanked fairy wrasse, blue damsel, watchmen goby, some hermits, 2 small zoa colonies, umbrella mushroom, some green mushrooms, feather duster, peppermint shrimp, sally lightfoot crab, and a variety of snails. So my question is how can I make this upgrade as simple and stress free for my livestock.

Honestly that's not a huge change as far as water, rock, sand volume etc.

I personally would would move everything at the same time to the new tank. I would use new sand and just move my existing water and rock over with the coral and fish at the same time. Ditch the old sand. You really want need any new rock right up front and maybe not at all. I have done this type of transfer several times once from a 75g to a 120g and a 120g to a 240g.
