Moving Aquariums: Need help game planning!

[KingAlee]

So I am officially getting my own fish room… after months of my tanks being in one of the living rooms my wife caved and said I could have the attached house. That being said I need to move two 125G and a 75G (which is only freshwater). How do I do this without crashing everything? Tubs? Lots of tubs? I’m trying to not have to replace the water because all tanks are already cycled. Could I just take the water out and leave the minimum in it for the sand and put it back in or… I need help with game planning here!

Adding this: saltwater tanks, only one tank has fish, both have coral.
