Transfer data from micro sim card to nano sim card?

I am getting a new iPhone 6 Plus through my Verizon account. I would like to give my iPhone 5c to my daughter. She has an iPhone 4 and her account is with AT&T. I understand her phone has a micro sim card and that my old has a nano sim card. How do I transfer the data from her micro sim card to my nano sim card? Or is that what I need to do? I don't want to try manually trimming the micro card. That sounds way too risky.
