What decides rank up options per * level?

New to forums so please forgive me if this is not the right way to ask this.. but I was curious what decides whether or not you can rank up a champion with units.
Ie: I can rank up a 5* champ with units but not 6* etc.
Is it a story progress thing? Do I have to have a certain number of 6* already at the higher rank?
