change device

Now I have platform that official licensed version so I can only be used to activate two devices

Im going to change my devices to i-phone to MacBook
Could you tell me How can I change it

I just want to keep my iPad


It is not very clear to me what you’re trying to say. The iPad version and the Mac version is purchased and licensed separately. If you activated with a discount/voucher code, it’s limited to 2 Macs. If you then want to switch to another Mac, you’ll have to deactivate one first.
