if you're going to be moving then you'll be tearing down the system entirely already. depending on what critters you have in the tank, you might want to consider doing a complete substrate swap as part of the move. You should be able to do this hopefully without starting another cycle.
Basically, when you move, Keep all of your current substrate seperate (in a few buckets or tubs). Set up the new tank with all sand (good old southdown/yardright is your friend!) Include a few good pounds of fresh LS
from your LFS
or friendly fellow reefers. When your tank has the LR
and water returned to it from the old set up (you should keep as much of the water from your tank as you possibly can during the move) Go to the dollar store and buy a box of cheap plain pantyhose. Fill these pantyhose with your old substrate to a managable size. Lay these panty hose directly on the new sand bed. I would use as many pantyhose as you can fit on the new sand bed. Leave them in the new setup for a couple weeks. With the bacteria on your already established LR
and in the substrate in the pantyhose you should be able to avoid a cycle (but check your parameters frequently anyway!)
the bacteria and pods
/worms etc will spread to the new sand bed over time. After a week or so you can start removing the pantyhose one or two at a time every few days until they're all gone.
