I've moved my 80 gallon reef twice and, never seen a measurable "cycle"-- my best advice is: "expect the move to last at least 2 days, and then plan accordingly."
For me, that meant:
-making sure you have enough heaters for ALL of your livestock containers and as much of the liverock as possible. (Because if you can keep your LR warm, and fully submerged in tank-water--then you'll have less worry about a post-move cycle afterwards.) Big coolers with trash-bag liners work great to keep things warmer in mid-January...
-test your heaters in the actual move-containers, and cold environment, BEFOREHAND (a 50w heater in a 5 gal bucket will act differently in your living room, than it will in a open trailer...). Leave them setup over-night with a digital thermometer that records min/max temps. (you want to make sure they're stable and that the temp. doesn't swing over-night--in case something has to stay in the bucket overnight on move-day.) Also nothing is worse than losing a whole container of livestock because 1 heater gets stuck "on", or was accidentally set too high.
-plan to have at least 100% of your new tank's volume of fresh saltwater water ready at your destination. Save as much of the original tank water for transport as you want, because knowing you have a full tank's worth of new water (already buffered to match the original tank params) at home is great as you begin to unpack/acclimate live stock. (And If you do use less than 100% of the new water, then you'll have extra for that first WC already ready.)
-I've kept all the live-sand, in the tank, on both my moves--and I've yet to have a noticeable cycle afterwards. (80 gallon glass tank + 1" sand + 1-2" of water is still a manageable 2-man lift.) I always spent at least 45-60 minutes carefully cleaning/siphoning the sand bed on move day. But I usually also leave any delicate specimens out of the tank on the first day because the water can take a long time to clear.
Remember, remember, remember: there's a good chance that you won't get it all done in 1 day, so plan to spend at least 2 days on the move at the outset. This way you don't have to rush, or stay up all night, because of poor planning. So when you put something (rock, fish, etc) in a container at origin ask yourself "can it spend the night in there?" does it have a heater? is that water buffered?, etc.)
For me, a tank move has always been a 3 day process:
Day 1 = tear-down, relocation, then tank/equipment set up, LR/aquascaping and fish acclimation (if I'm lucky).
Night 1: Corals (and/or delicate fish) sleep in their move containers, or temporary tanks. (which have already been correctly temperature cycled; because we planned ahead.
)
Day 2: livestock acclimation, coral placement, and LR tweaking.
Day 3: lots of rest.
