Hiya Justin, once you cut it away from the tree you will have bees everywhere trying to shoo you away so suit up and tuck in.
I'd imagine, on a fine day, cutting it all off the tree then putting it into a big box or rubbish bin and transferring to the ground before cutting the comb to fit the frames try to keep the same orientation although apparently it's not critical. Not sure what you mean by vertical. Once cut, band them in an unwired frame and place into the hive one by one would be the way to go. It will take a while. It will be messy. You will kill a lot of bees, hopefully not the queen. More than likely you will be stung.
It's always good to leave the new hive at the old site however this may not be an option...
Good luck and let us know how you go.
