Do this on your iPad:
What to do before you sell, give away, or trade in your iPhone or iPad - Apple Support
After all the steps are completed, set the iPad up using the same AppleID
as on your iPhone.
Be advised any apps/media/other downloads acquired by the old AppleID
are forever tied to that AppleID and cannot be transferred to your new AppleID.
