No big deal, just a BIG difference in the steps you would want to take. Have you tested the water at the new place to see how similar (or different) it is from your current water? If its drastically different, bringing a good amount of water from your old tank will help with acclimating them.
I'd bag up any fish close to last in one gallon ziptop bags, with as much air trapped inside, plus a drop or two of StressCoat+ or Prime to deal with ammonia. I'd probably go with 1-3 fish per bag, depending on the size of the fish.
I'd also take them over in an insulated box - picnic style to keep the temp as constant as possible, and keep them in the dark.
I'd remove the substrate from the tank and move the tank completely empty, less chance of any type of mishap.
I'd bag up any live plants with water (no need for air in these bags though) - the plants will need to adjust to the new water as well, so again, bringing as much of the old as possible will greatly help them.
Finally, I'd leave the fish in the tank for as long as possible, and add them as soon as possible (once the new tank is up to temp, of course). I'd actually consider bringing as much of the old water as possible - even though its going to be heavy - and do small water changes (10% or less) over the course of the next two weeks about every second day to slowly acclimate the fish and plants and reduce shock as much as possible if the water is very different.
That's about all I can think of. Did I skim past something?
