I moved ~1000 miles from Chicago to Atlanta. It was a lot of work and stress, but i dont regret it. Kept all corals and fish... minimal losses (1-2 rare mushrooms and 1 acro).... out of maybe 30-50 coral varieties.
Made a few frags of ALL coral colonies. Sold all except 1 colony, and kept all frags. Used the money to upgrade equipment.
Pre-cycled lots of live rock for several months; dosed regularly with food to slowly build up the bacteria. Set up the new aquarium for 1 week before transporting any livestock... Leveled the tank, checked for leaks, played with the aquascape, allow bacteria to settle from the rocks onto all the pipes/sand/etc...
Transported Livestock with a bunch of air pumps by car. zoas, softies, and clownfish first...etc... saved acros and sensitive corals for last. Never kept all my eggs in any one basket until the end (hence frag multiples). Very stressful, and everything gets wet.
Coral colonies dont fare well with moves. My 1 colony was so darn stressed... I ended up fragging it after a few months. Half the frags died, but others lived, so it wasn't lost.
EDIT: I've also moved across Atlanta (Dunwoody to Marietta) with minimal losses... same deal.
