We're converting a CSS 11503 config to the ACE 4710. Is it possible to transfer the existing SSL certificate from the 11503 to the ACE? Or, do we need to generate a new key pair and CSR on the ACE? I did some searching and the closest I came to an answer was "If you have preexisting certificates and matching key pairs, you can import them to the desired context on the ACE" but this doesn't tell me if the preexisting certificates and matching key pairs have to be from another ACE or if they can also be from a CSS. Thank you.
