Regression (reverting from a higher model to a lower) generally doesn't cost BP. In case of teching up, it depends on individual ships.

Suzuya/Kumano K2 CAV>CVL conversion costs BP, so a BP is required EVERYTIME you "tech up."

It's best to keep a dupe as different type if you can afford the slots.
