Hi, i just wanted to ask a quick question regarding generating new certificate.
I have migrated my site from server (VPS) A to B, both running Apache, with /etc/letsencrypt copied to server B as instructed here, no problem since the cert hasn’t expired. Then i turned off Server A completely (as i suspect there’s been a breach) with the intention to delete the server later.
Now if i want to be safe and generate new certificate on Server B by installing Certbot, should i delete or revoke the old certificate on Server B prior to that?
Does the process of installing Certbot and generating new certificate automatically invalidate the old one? What should i do to make sure the old one is permanently inactive?
