I'm in the process of moving between 2 servers. On the first server, I generated the .key certificate, and submitted the csr code to buy the certificates from Comodo.
Comodo gave me the chain file and the certificate, which I installed on the 1st server.
Now, I'm moving to another server, and my question is: Since I've not generated the .key file on the 2nd server, will my SSL work if I simply copy and paste the 3 certificate files from server 1 to server 2?
Or do I need to generate key file with the 2nd server, then buy the certificate for the 2nd server again?
EDIT: The certificate is for the domain, I've set up the hosted zone on AWS, and the last step is to simply change the name servers.
