Suppose, you have purchased a new Linux server and going to transfer all your domains residing on existing server to new server. In such case, you may require to transfer the shared SSL certificate installed on your domain to new server.

If your domain name and host name remains same for both the servers then you can directly transfer existing SSL certificate for the domain hosted on old server to a new server.

You just need to copy and paste following files from your old server to new server:
  • /etc/httpd/conf/ssl.key (private key)
  • /etc/httpd/conf/ssl.csr ( CSR key)
  • /etc/httpd/conf/ssl.crt (certificate file)
