[Pki-users] Renew expired OCSP system certificates

Hi all, Good day to you all. What is the process to renew all the four system certificates (SubsystemCert, ServerCert, ocspSigningCert and AuditsigningCert) when those existing certificates are currently expired. I cant access the pkiconsole also as the system is not up and running. I have used the certutil to generate the certificate requests and get it signed by the CA. But it didn't work as expected. I believe the procedure that i have followed to request generation or the signing profiles used for the generation, may have some issues. Cheers. Regards, Mark
