What I could do is do waterchanges for a few weeks using water from the new tank lol. Dump the old water into the new tank.

And yeah think I'll grab all my new rock and let it cycle. I never had a cycle last time and maybe I'll get lucky again.

Oh, I didn't know you had already filled the new tank with new SW. If you're adding some new live rock it's a good idea to let it cycle. You may not get much of one though.
I just don't like to add livestock to brand new water. Even a large water change can sometimes shock the animals. Don't know where I read it but it was recommended to never change more than 50% of the water unless of course it's an emergency. Too hard on the critters.
