• For a CA-signed renewal, the root CA certificate is uploaded to the matching -trust store first, then any intermediate to -trust, then the CA-signed identity certificate. in context
• The CA-signed renewal technote for 14.x and 15.x warns that regenerating the CallManager and TVS certificates at the same time causes an unrecoverable mismatch with the ITL installed on endpoints. in context
• Only one CSR can exist per server and certificate type. Generating a new CSR replaces the previous one. in context
