My web server physically died...I have a new one in place. I have the old hard drive and just recently renewed my Certificate. I have the site alive - but need to re-implement that Certificate.

In this case, if your old hard drive can't actually be booted into the OS, I think your easiest solution would be to regenerate a new CSR on your new server.
Before you submit it though, you would have to go to your cert authority, and revoke the old certificate. (you may be able to do this online, or you may have to contact them).

Once the old certificate is revoked, then you can submit the new CSR and process just like a new certificate.

Hope this helps.

The hard drive won't boot because of the change in hardware...but it is live and I also have copies of the Certificate

oh ok, well if you have a .pfx backup of your certificate, you can restore the cert on your new server.
(the .crt file alone will not be enough, as you need to have the associated private key in addition to the certificate).
This article has the steps to backup the cert (if you can still boot up that hard drive temporarily : 

Also, a requirement for this, is that your new server is named exactly as your old one, otherwise, the certificate will throw an error saying that the name of the cert doesn't match the host it's connecting to.

the answers were not wrong...just not right on what i wanted to do. While they would have worked...stunnel took care of it. I was able to simply use what i had on the old drive and place it on the new one without revoking, or going through all the orignal steps again. My three year certificate is in place! Thanks!

Effort counts so works better if they know someone else is helping.
