I think when i migrate one server to another i did migrate some ssl certificates i not need anymore. so when i do ls /etc/letsencrypt/renewal i get: Code: root@server4:~# ls /etc/letsencrypt/renewal server1.cl-i.net.conf server2.cl-i.net.conf server4.cl-i.net.conf i think this certificates i took from one server to another server so if my actual server is server4 can i delete as well server1.cl-i.net.conf and server2.cl-i.net.conf? thanks a lot for your help guys
