This was taken from Ciscos website. You will have to take the CCNA again before you can take any CCNP.
If you had a current CCNA, then you could renew it with CCNP. But since your CCNA is expired, you need to start again ie do ICDN1 + ICDN2 again.
All the painful detail is over here: Certifications - IT Certification and Career Paths - Cisco Systems
