I recently migrated a website from a server running IIS 6.0 to one running Apache 2.2.x . While the migration of the sites was a snap, I also had to migrate the SSL certificate, and this was a little more involved. Here are the steps I used.

Note: The new server was also a Windows box so I installed the Apache binary with openssl. Your apache installation may need to be recompiled with ssl for it to function depending on your OS.

Step 1: Export .pfx file

When migrating a ssl cert from one server to another you will need both the public key files (your SSL certificate files, provided by your Issueing Authority)and the associated private keys (generated by your server at the time the CSR was generated) for the SSL certificate to function. For this reason a PFX backup is always needed to transfer an SSL server security certificate from one server to another.

Under windows do the following steps

  1. From the Start menu, select "Run...". Type "mmc" and hit Enter.
  2. Under the File menu choose Add/Remove Snap in.
  3. Click Add, then from the Add Standalone Snap-in panel choose Certificates, and click Add.
  4. Choose Computer Account and click Next, then choose Local Computer and click Finish.
  5. Close the Add Standalone Snap-In window by clicking Close.
  6. Close the Add/Remove Snap-in window by clicking Ok.
  7. Click the + to Expand the Certificates (Local Computer) Console Tree
  8. Look for the Personal directory/folder and select Certificates.
  9. Right Click on the Certificate you would like to backup and choose > ALL TASKS > Export
  10. Follow the Certificate Export Wizard to backup your certificate to a .pfx file
  11. Choose to 'Yes, export the private key'
  12. Choose to include all certificates in certificate path if possible. (do NOT select the delete Private Key option)
  13. Leave default settings > Enter Password (if required)
  14. Choose to save file on a set location eg "desktop/mysite.pfx"
  15. Finish, you will receive a message > Export Successful
  16. Copy the created pfx file to the apache server
