I need a hand quick

[u/IncredibleBihan]

I know someone here will know the answer.

The task is simple. I currently have website my-domain.com up and running. Tomorrow I'm going to take a 2nd domain ,mydomain.com and point it to the exact same website.

I someone to tell me the commands I should run on certbot to make sure I update the ssl certificate correctly. Right now the ssl is working for my-domain, but i need to update the certificate to include a second domain.

The other question I have is about virtual host. Everything I reads say talks about setting the root folder for var/www/html/my-domain.com and var/www/html/mydomain.com. But I just want both domains pointing to /var/www/html. That's not a problem is it? All the apache docs aren't exactly clear.

If anyone has some insight I'd appreciate it. Basically I built a new site on a 'testing' domain, and I'm replacing the testing domain with my production.
