Do it! It is leaving it to chance - people move all the time without pre-cycling a new tank. You may or not have loss. People are just mentioning that you have two tanks and thus you could have a far better situation but if you can't - you can only do what is possible.

I just moved my tank 2 months ago, and used maybe 25% old water and the rest new. The only thing I added (frankly I probably could have got away with out it) was bacter boost. Basically like microbacter7 but a different brand. No problems other then and sps rtn on me. No big loss.
If the rock has been in the tank long enough with regular water changes it should be cured anyway, so you really shouldn't see much if any cycle. I didn't even see Diatoms or any spikes after moving mine.
