changing apple id

Originally I set up my own apple ID and then got a different phone that I had for several years. In the meantime my daughter was using my apple ID. I have just switched back to an iPhone and want to start using my ID again. How do I get all of my daughters content off of my ID and on to her own. She changed her ID on her phone but all of her contacts, music, etc. is still on my phone because I'm using the original ID.
