Don’t feed the fish for a few days prior to the bagging.
Bag or Bucket the Fish. If it is small and from a temperate zone, you got 48 hours. As little water as possible, as much air as possible in the bag. Don’t blow into it with your mouth, you want O2. The more delicate the fish, the less time they can spend in the bags. Just know, this act starts the timer. Temps still matter, but most are fish fine at room temp in a bag for 24 hours or so.
Bag or Bucket the Plants. The good news is they can all go together and they don’t need much water. They DO have to be kept moist…. some wet paper towels work well between clusters of small plants, or wrapped around bigger ones.
If you can keep the canister filter upright, you don’t have to drain it. Garbage bag for the filter, garbage bag for the hoses keeps most things (and car interiors) clean and dry. If not, or if you have a HOB, throw the filter media into a ziploc and pack the filter.
Drain the water, as much as possible, then drain it some more. Moving Weight destroys tanks. Consider dumping the existing substrate outside and getting new. Pool filter sand and blasting media will cover the bottom for less than $10. If you bought EcoComplete, get a plastic cup and another bucket.
Move the stand to the new location. Level it. Check the level again. Remember to check it front/back, left/right, and diagonal.
Place tank. Check the level again.
Place several old towels around the bottom of the stand, then quarter fill the tank with water. Wait an hour, check the levels. Check to see if the slightly popped seem is now a rushing stream. It probably is. If not, and it not leaking, add substrate, plants, filter, and refill with water as close to room temp as possible. Dechlorinate, and add fish.
((The fish have spent the last several hours, at least, at room temp. Putting them back into the tank full of room temp water keeps you having to float bags and gets them out of the bags faster. And, of course, if the water is of vastly different chemistry, you will have to drip acclimate.))
