Ed,
I have an advice for you... I've have to move my two nanocubes twice last year, and I would not recommend moving it with any water at all, even if you are moving 15 minutes away. I moved less than 5 minutes away from where I used to live, and I transferred my corals and fish to a Rubbermaid tub, and placed the LR in a few Home Depot 5 gallon buckets.
The only thing I left in the tank was the SB, with enough water just to slightly cover the bed. Especially with the nanocubes, I think it's better to be safe than sorry, and your fish should be fine in the tub, while the tank is not set up yet. I premixed 10 gallons of water a few days before, as you will need more water to fill all the containers.
