Transfering the fish but not the Ick to a new tank?

[desjardinii]

I'm planning to upgrade my tank to a larger one and would like to know the best way to go about transferring the fish, live rock and corals over but if possible not any of the Ick I have in the system. The fish are all medium to large and I have approx. 150lbs of LR. I need to weigh up whether trying to eliminate the parasite using one of the preferred methods will be better in the long term or if a much less stressful, fast move into the new tank using the existing water etc. will be better for the fish. I haven't actually lost any to Ick in nearly 10 years, some have never even shown a symptom but it would be nice to be 100% Ick free.

Tank transfer as described in the stickies.

You can eliminate ich from the fish via TT but it will not eliminate it from your tank.

if you already have ich in the system, it can carry over on the live rock, in the water, and even on the corals.

not quite sure i understand your reasoning...if you have never seen symptoms, never lost a fish, what makes you think you have ich in the system?

Some of the fish have never shown any symptoms whilst others have so it's definitely there, It just hasn't caused any deaths -yet.
How would I go about the TT method with 10 med to large fish? Or would I be better off setting up the new tank bare as a big QT with canisters. sponge filters etc and using copper? but I'd be terrified of poisoning them. The old tank with the LR and corals can be left to go fallow.
Any suggested plans of attack would be much appreciated.

Unfortunately, you would need to treat all the fish as infected. You could setup a large hospital tank and treat accordingly (copper, hypo, CP, etc). After the treatment is over, you would keep them in the tank until your DT fallow period is over.

You may be able to perform tank transfer with two large enough containers, but you're going to need some space...The big treatment tank sounds easier. I'm curious what others suggest.

+1^ this is exactly what I am doing currently. TTM works great but is much easier to with fewer/smaller fish. I'm using CP and paid the price for underestimating the amount of bristle worms in the 4-5 pieces of rock that came over from my DT. First time not using a ammonia badge and the last. Have lost 8 fish now because of it. Only the established fish were able to pull thru. Literally piles of worms dead/dying, ammonia was thru the roof I'm sure never even checked it. 75g water change and 1000g worth of bacteria on a total hospital/QT setup of 250g
