Just breath. It will be ok, I was in your shoes just last week. I actually had to move twice. I had to move to a hotel and wait for my house to be done, then now into my house... I combined all my fish into my 15g and just over filtered it, while I secretly kept it in a hotel.... Everyone survived the stressed, cramped, over-crowded situation.
I went out and bought a plastic tote from Walmart and that's what I transported my plants, filter media, and fish in. I used my gravel vac and drained a carriable amount of water into the tote, about 5 inches of water, then I netted everyone into the tote. And dumped out the rest of the water in my tank, except maybe an inch at the bottom....
Depending on how long of a move your doing your fish will be fine in just the tote, if it is going to be a considerable length of time then you may consider putting your tank heater and filter in the tote.
*make sure to keep your filter media moist in fish water, so the BB survive the move too.
Just keep calm and plan for the worst, hope for the best.
I figured is lose 1 or 2 weak fish that wouldn't be able to handle the 1st move, and to my surprise they all made it.
On the second move (3 weeks later) I really figured I'd lose some fish from the combined stress of them all being in one tank and a 2nd move. And to my surprise again they all made it!
