Hi I have the problem that I not have a CSR of the certificate by changing the server, is there a way to create it via panel or must i need to create it via the console?
Certificate for what? Is this about Let's Encrypt certificates or have you purchased a certificate? I did not understand the "changing the server" -part This may help, but I am not sure since I do not know what the problem is: https://www.howtoforge.com/tutorial/securing-ispconfig-3-with-a-free-lets-encrypt-ssl-certificate/
i habe a new ispconfig server and i transfer now all domains from a i-mscp server. a customer have a purchased wildcard certificate and i must renew this certificate. but i have only key,certificate and ca-bundle. the question is can i create a CSR via panel without destroy the installed certificate or must i create it by hand?
You will have to create the csr by hand. ISPConfig can create the csr but it will overwrite the currently installed ssl cert with a self-signed one.
Yes. But you will have to copy (backup) the old cert and key, then create the new csr, then copy the new csr and key and put them in a safe place before you restore the old cert and key. cert, csr and key belong together, so the new csr will have a new key, that#s why you have to restore csr and key.
