I currently have one host - host1.myDomain.com - this hosts several other domains (Virtual Servers) which all have SSL enabled and LetsEncrypt certs issues without any issues. The host runs Postfix and Dovecote among other things (MySQL, etc but no BIND).
The host (domain - myDomain.com) also has a cert - which Postfix uses.
I want to bring up another host - host2.myDomain.com and slowly move all the hosted domains across. I have a plan in mind. The question that springs to mind is:
- will LetsEncrypt issue another cert for host2.myDomain.com & for myDomain.com, without revoking or affecting the existing one?
I will be adding another A record for host2 in the 3rd Party DNS panel for host2 & it’s IP address first.
Looking on host1 & myDomain.com in Virtualmin (Server Configuration >> SSL Certificates >>Let’s Encrypt) , there are 3 entries listed in “Domain names listed here” field,
I would think that once Virtualmin is installed on the new host, it would have
Would that work - without messing up the existing cert on host1? If not - any advice?
