Bed transitioning from crib to bed

My daughter will be 21 months this month. And she still is in a crib we want to transition her starting in January as we have a new one on the way due in early may. What is the best way to transfer her. She’s never had an issue with climbing out of her crib as she never has climbed out. So I’m wondering if there is any tips or tricks to help ease the new bed experience for her. What have you parents done ?!
