It depends on what your moving i.e SPS, LPS, Softies and what size tank. Buy some large trash containers place liverock into one, corals another, old tank water another, and fish another. You can use a power inverter, and a pump for circulation. Some, if not most bag the corals for safe transportaion. This prevents fighting if you have a mixed tank as well as keeps them from tumbling around and breaking during the transport.The rock just needs to be barley submereged. If yu don't own a truck rent one and have man power on hand. Then if you have a sand bed or a DSB you have to prepare to move that (I'll let some else more knowledgeable tackle that portion).
You should have the tank and stand moved and pre setup (using as much old tank water as possible to prevent a spike) to receive your preciuos cargo. You should aalso have some water pre mixed just in case. This is a rough overview and there are threads located on this site about making moves a of varying magnitudes, also some more knowledgeable folks might chme in as well. Just remeber it's better to plan, re-plan, and plan again because mistakes can be very costly.
