I'm working with Lightsail for a single domain, and also have a lightsail load balancer in place. Under the domain I have a few subdomains (blog.mydomain.com, admin.mydomain.com etc) - all of that is working just fine.
However, I'm now trying to roll out another subdomain (for an AMP mobile version), which also requires that I use https. As I understand it, because I can only 'attach' one certificate at a time, the only way I can add this subdomain is to delete the current certificate & create a new one with both the existing subdomains and the new one I want to add.
So, I have 2 questions;
1) Firstly, is my assumption correct that I will need to delete the existing certificate & create a new one?
2) If so, when I create the new one will the CNAME names & values be the same as the current certificate, or will I have to re-do all the dns entries too?
Many Thanks in advance!
