You're better off with any new snake to make their new home seem as familiar as possible, so I'd suggest copying the previous methods until your snake has "settled in" & taken at least 3 meals for you at normal intervals (ie. without too much begging on your part, lol). Only then is it wise to make changes, & if you choose to do so right away, the snake is more likely to refuse just because it's already freaked out enough by the move itself. New homes are very frightening & disorienting to snakes- in nature, their safety depends on learning their way around- where to hide from predators & weather.
I do totally advocate feeding f/t or at least freshly pre-killed, not only for convenience but also for humane treatment & especially for safety- sooner or later, snakes do get bit or chewed on by rodents they're trying to kill, & even if the snake wins the battle, those injuries can later be the "rodent's revenge"-not to mention the cause of expensive vet bills.
