I have an SSL certificate associated with a load balancer on Amazon Web Services. I would like to have an additional domain on that certificate. My questions are:
Is it possible to add an additional domain to an EXISTING ssl certificate on aws? I see that you can add additional names when you create one, but I don't see how to do it with an existing certificate.
If no to 1, is it possible to associate 2 certs with the load balancer? Or do I need to create a new one that includes both domains and replace the cert with the new one?
Thank you for your advice.
The simple answer is a resounding Yes! You absolutely can use one SSL certificate for multiple domains — or one SSL certificate for multiple subdomains in addition to domains.
Yes, you can transfer an SSL certificate you bought elsewhere. If your site is coming from a host that uses cPanel, these can typically be extracted from cPanel directly or from the file manager.
To replace the SSL certificate for an HTTPS load balancerOpen the Amazon EC2 console at https://console.aws.amazon.com/ec2/ . On the navigation pane, under Load Balancing, choose Load Balancers. Select your load balancer. On the Listeners tab, for SSL Certificate, choose Change.
Actually (as of Feb 12, 2019) you can request another certificate and then Add to your load balancer. I just did this myself. I had one certificate with 5 domains and I didn't want to have to create another just for one more. So I created the new certificate for the one domain and then added ( look for a plus sign ). Easy and it takes effect right away. Good luck.
