you know your daughter best. how has she done with transition in the past? for my daughter, if we make something sound exciting, she thinks it's great, and does not have any problem. she moved to a new house, put her in a toddler bed, and FULLY potty trained her in 3 months. she was 26 months.
here are a few things to consider. anything that is considered something for "big girls" will require your daughter to listen and obey you. if you have any trouble with this, you may want to work on that first. if not, then you should be fine.
my daughter never climbed out of her crib, but i thought she was ready for the toddler bed. we gave her the "big bed rules" and asked her to repeat them each night for a while - no jumping, no standing, and no getting out. if you see or hear her getting out, go and remind her of the rules...
i don't see the bed thing as a difficult transition...
potty training is a tough time. i didn't want to do a drawn out thing with pull ups and all that. we did the "intense" straight to undies thing with lots of excitement and treats for going and staying dry. i didn't think she would stay dry at night for a while, but after the first week she was dry at night. i continued to use diapers ONLY at night for a few weeks, and then one night i forgot. she had two accidents after that, about 3 weeks later and NONE at night since then.
i wouldn't expect your daughter to be ready to get up and go to the potty at night by herself, so you don't necessarily have to get her to the bed first. my daughter is about to be 3 and still calls me for help to go potty in the night. i am glad, because it means she is not wandering around by herself, and even though the feeling wakes her, she is usually still pretty sleepy.
all kids are different. you have to do what you think she's ready for, but know that anything is possible.
