The Great Tank move....

It looks like in a few months I maybe moving and have some questions to
ask about moving a tank.
First off, the tank is a 45 gallon reef tank with various zoolanthus
polyps, green star polyps, and a few pieces of cabbage leather coral.
There are various snails and blue/red legged crabs, emerald green crabs,
brown serpent star, yellow tang, clarki clown... Ok so you get the picture.
The filtration for the tank is a UGF (yes), and an Aqua C Remora Pro. I
have an old biowheel filter that I use for carbon but does not have the
bio wheels or any other filtration thing on them. It also is used for
additional surface movement for the tank.
I hope I covered all the bases... Now when I move I was thinking about
purchasing another 45 gallon tank and setting it up ahead of time and
doing a DSB and getting rid of the UGF all the way. Would this be a
good idea? I would hopefully set up the tank probably a week before I
was moving in and maybe take a few smaller pieces of live rock and stick
it in the tank, then move everything a week later. Is the tank going to
cycle and kill everything? I hope this is not too confusing but I want
to be on top of everything when I move so this will be as painless as
possible. Any recommendations or even directions to web sites would be
greatly appreciated!!!! T

Thanks!!!
