[CentOS] Export/Import wild card SSL

Hi all,

This topic is one that I am ignorant on and appreciate any guidance.

My scenario;

I have a wild card SSL installed on one of my CentOS boxes.

As I understand it, this server was used as a sort of master when originally generating and receiving the wild card SSL cert (got the cert from GoDaddy BTW).

So, now I must export some file(s) from that server so that I can import it/them to another server.

Were do I begin?

I did manage to generate a .cer from a pem belonging to my master server via;

openssl x509 in ca.pem -inform PEM -out somefile.crt.cer -outform DER

But I honestly do not under stand what I did here and have a feeling this is incomplete as aren't public and private key involved some how?

I have my ca.csr (my request file), ca.key (my private key) and ca.pem (my public key) files in hand and ready. A backup has been made for testing.

Thanks in advance for any info.
