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)
