Also, how far is the move? If it's fairly close, the I'd go the rought of filling the tank in the new house with water from the old. Or even if you have several buckets, the original tank water and with what you don't have enough buckets for, then make a run to the old house and fill the rest with water from the old house. Then acclimate the fish. Then over the course of a couple weeks, can do 20% weekly PWC's to slowly change the parameters to match closer to the water at the new house.
But if it's over a distance, then bring the fish over and acclimate very slowly. They should be able to handle it with minimal stress if done properly. IME, the fish seem to handle going from harder water to softer water much easier than the other way around. And that's what a couple other breeders have told me as well, as they prefer breeding in harder water and sending out the fish, as it's easier on the fish to go from harder to softer, than it is the other way around. But even then, proper acclimation is the key.
