If you use all the old sand, all the old live rock, all the old water and don’t overstock it with fish right away and old lights it’s very doable. I did it 4 years ago with no issues at all, just had to add around 40 gallons of new water as I moved to a bigger tank. By using all the old established stuff I skipped any type of cycle and corals Andy fish were acclimated to the new system instantly as everything survived with no regression.
