Ich only takes around 10 days to cure with salt & heat. Assumning you cure it, you should be fine.
What kind of filter are you running? Best bet for a fast cycle is to take some of the bio filter media out and put it in the filter of the new tank. Lookup "fishless cycle" too. Just takes ammonia, and doesn't harm or kill any fish. Also, Ich supposedly can't survive without fish present. So if you are doing a bio-jumpstarted fishless cycle at 85 degrees for 2 weeks you can pretty much guarantee that tank is ich free.
