I want to migrate my website to a new server. Could you help me, which is the proper way to deal with the Let's Encrypt certification;
Should I issue a new cert in the new server ?
Thanks a lot!
My domain is: www.scti.gr
My web server is (include version): Apache2
The operating system my web server runs on is: Ubuntu 18.04
You can move the entire /etc/letsencrypt and /etc/apache2 directories to the new server, or you can issue a new cert. (be careful, you can't use http and tls-alpn verification if your dns records point to the old server.)
No, if you want to issue a new certificate on the new server you only need to wait some seconds/minutes after updating your dns records (depends on your dns provider, some need hours).
