I pretty much do it the same as nc. I make sure to have a few buckets of extra tank/treated tap water w/ me from my old place to drip acclimate/do any water changes that might come up. I'de had buckets tip over, styrafoam containers leak ect. extra buckets of water/containers are all good insurance for an "oops" that may happen. Also recomend if possible seperateing each fish into it's own container if possible, or at least keeping fish such as plecos and catfish or anything with spines seperated. I have lost fish due to not seperateing out such types of fish, a solid spook can cause these fish to rip themselves up and anyone else w/ them by accident. I also personally put all my bio-media in one bucket w/ water, and avoid putting objects w/ the fish that can smush/poke,ect. floating plants seem to help w/ anxiety in many fish though.
Just use abit of common sense and you should be fine.
also avoid feeding them 24-48 hours prior to moving them. and a day or 2 after acclimation to the new place. I've had some fish take food right away, and others refuse for days.
