How to backup SSL and reinstall to clean IIS?

I have IIS current configured with a web site and SSL certificate installed.  I need to redo this server and I don't want to have to pay to re-issue the certificate.

I went through the wizard and exported my current certificate to a .pfx file.  Will I be able to use that file to re-install the certificate after I have a new clean install of IIS?  There was another option in the wizard about copy/move your certificate to a remove server but I wasn't sure if that's what I wanted or not.

Any info would be great.  Thanks!

You can select the certificate and back it up. You can then use this backup file to re-import to the new server(s). When backing up, you assign a password which will be needed to import later. Do not forget it or you will have to redo the backup.

You don't need the cer file anymore.

I also still have my original .cer file if that helps...??

So this .pfx file that I have is what you're talking about, right?  I created a password when it was created.

Yes. Keep it safe. I generally export the cert as soon as I install it as backup or to propagate to other servers.

So you can install the cert to multiple servers at once???

Yes, like for a web farm. If you use a load balancer, you could put a single cert on it and it passes requests to the web servers that don't have or need certs.

reinstalling IIS doesnt affect SSL in the least.  they are completely separate.

northcide:  I don't understand.  How can they be completely separate?  In order to install the certificate I have to go through those wizards inside of IIS.  Or at least that's how my ignorant a** always does it.  ;)

What am I missing?  Here's really what it all boils down to.  I have an SSL installed on my web server at home.  A little while back I had to format that drive and reinstall it all.  I wound up having to pay for a "re-issue" of my SSL from rapidssl.com.  Went through the whole process again and was then back to normal.

I'd rather not have to pay when that happens.

If you are reinstalling the OS and IIS, you will probably lose the cert. If you just reinstall IIS on top of itself, you will probably still have the cert. In any case, don't depend on it. Just back it up as discussed earlier.

If you want, try importing it on another server just so you can be sure it works and be familiar what to expect.
