From what you've said in first post (in reference to her likely age & how long her previous owner had her) it's probably safe for you to use substrate that will enhance the humidity rather than paper towels* (*which are used with newly-acquired snakes for a month or so while making sure they don't have mites. If this snake had mites for that long of a time, she'd not be alive now, so she's unlikely to have mites, IMO.)
for not handling her any more than is absolutely necessary- & preferably waiting until after she's eaten at least 3 times at normal intervals. Otherwise, the stress (& fear) of all the changes being in a new place can make a new snake refuse food- even when they really need food, so it's best not to risk that.
Going from a small tank to such a large one might make her feel afraid (with so much open space that she's not used to- since BPs are "ambush predators" that stay hidden & don't hunt actively- they mostly just pounce on prey that gets too near where they're hiding) so be sure she has several hides (one on cool side, one on warm side, & optional "humid hide"), some "clutter" (other furnishings like fake vines etc.), a water bowl of course, & it would be a good idea to cover the back & each side of the glass tank with dark paper or cardboard for privacy (this can also add some "insulation" if you live in a colder climate- the larger the tank, the harder it is to maintain the warmth that BPs require).
