So, I've never tried to move a planted tank, so I can't answer all your questions, but I have moved a 55 gallon tank from Northern VA to Baltimore & I can share some of what I learned and what I might have tried to do different. My 1st thought is "will the water be different from one place to another?
If the answer is no (local move) then drain the tank down to 1/2, move it and continue with your plans. You might want to add some bacteria boost during when you switch to your new set up. I would use stress coat during the move.
If the answer is yes, the tap IS different in your new home, save the 50% that you drain and dilute your new tap with you old (and dechlorinate the new water of course). If you already have the new tank & an old filter, you may want to bottle up some of your old tap and fill the old tank up with tap from your old home and continue to mix the new tap with the old tap in your back up tank during cleanings. The goal is obviously slow change during a stressful period.
That my ideas as far as the fish are concerned. Of course the more care the species of fish you keep need, the risk increases. I once traded in 3 Angels that I kept for 3 years because the move that I had to do (Indiana to Virginia) wasn't worth the try. My thought were to take the chance that some else local would (hopefully) love them enough to take care of them in the same town I bought them in, rather than put them through basically 2 days without filtration or heat.
I hope this give you food for thought as far as the fish go. I'm sure someone more experienced can give thoughts as far as your plants. I wish you luck
