what i did was set up a temporary system with a rubbermaid stock tank. I got this filled with saltwater heaters, etc. I then transferred my rock,fish, and corals to this system. I was quickly able to make the transfer and minimized die off on the rock and stress on the livestock. I monitored the system and did two large water changes during the first week in the new system.
Then I broke down the equipment and moved the equipment over to the new place. This allowed me to take me time in re setting up the system, including a deep clean on equipment, soaking pumps etc in vinegar.
Something to consider, especially when trying to move a large aquarium. You can get a 100 gallon rubbermaid stock tank for under 100 dollars.
