Okay.. wasn't paying attention. Upgrading is same same. Most important factors only you will know about your system and plug into BSII. Boil off rate, mash tun loss, kettle loss. Do some experiments to find the numbers and plug them in. Might take a few times to get it dialed in but then you'll be good. Make sure you update your equipment and batch size profile. If your equipment profile isn't in beersmith you can add it.
