I moved a 120 litre FW tank back in ‘94. I initially flew up with a new temporary tank, set it up in a friend’s house and let it cycle. A couple of weeks later I flew back up with the fish in foam boxes and introduced them to their new temporary home. A month later we did our big move, I setup the permanent tank in our new place and cycled it. A week later I transferred the fish from the temporary tank in my friend’s place to their new permanent home and broke down the temporary tank.
This isn’t as big as yours of course and was FW, but this worked for me at the time.
