When I transferred my 30 into a 46 g I had corals. Well my 46 went ahead and cycled just like a brand new tank and the high ammonia killed my corals almost immediately. I would strongly advise you to ask your LFS
if they'll house yours while your tank finishes cycling. That way you won't have to do PWC
and make your cycle last longer. My LFS
housed my candy cane which barely survived.
