Do you have multiple servers that need to use the same SSL certificate? This is very common in an environment where a load-balancer is used to share the load of a website across several different servers. This is also becoming more common as\u00a0wildcard certificates<\/a>\u00a0and\u00a0UC SSL certificates<\/a>\u00a0increase in popularity because they enable a single certificate to work on multiple different domains or subdomains using\u00a0SSL Host Headers<\/a>.<\/div>\n<\/div>\n<\/div>\n

What about when you set up a new server or\u00a0switch hosting companies<\/a>? How do you move the current SSL certificate to the new server? What if you need to move it to a different type of server? The answers to all of those questions are contained in the following pages. Essentially, you will\u00a0export the SSL certificate<\/strong>\u00a0from the server that it is currently installed on,\u00a0move the SSL certificate<\/strong>\u00a0to the new server, and then\u00a0import it<\/strong>\u00a0on the new server.<\/p>\n

Keep in mind that some certificate authorities, require that you purchase a “server license<\/strong>” for each server that you install an SSL certificate to, even if it uses the same private key. And speaking of private keys, it is\u00a0slightly less secure<\/strong>\u00a0to copy the SSL certificate and use the same private key on a different server. If an attacker breaks into one server and gets the private key, he will be able to listen in on the connections that other servers are making.<\/p>\n

We will assume that you have already successfully installed the SSL certificate on one web server. You will follow these steps to move or copy that working certificate to a new server:<\/p>\n

    \n
  1. Export the SSL certificate<\/strong>\u00a0from the server with the private key and any intermediate certificates.<\/li>\n
  2. Convert the certificate<\/strong>\u00a0to a different format if you are putting it on a different type of server.<\/li>\n
  3. Import the SSL certificates<\/strong>\u00a0and private key on the new server and configure your sites to use them.<\/li>\n<\/ol>\n

    Now on to the instructions. What would you like to do?<\/p>\n
