Is there anyway that I can change the expiration date of an existing certifcate (.pfx)? I  don't want to generate another certificate.

Thanks,

No.  You can't change the cert.  If you could... then it would defeat the whole point of a cert.

No. you can re-submit the same CSR to a CA, and get a new certificate with the same key, but you would still need to replace the old certificate with the new.
This is part of the design, but also part of the marketing strategy of the CA - after all, how can they sell you a new Cert every year if you could just re-use the old one?
