Removing Certificates from the Security Server
This article explains how you can remove certificates via the security server’s management user interface.
Note! If the security server is in use, certificate removal must not begin until the new certificates have been installed. This ensures that replacing certificates does not interrupt the organisation’s services, as the security server remains operational.
Instructions for renewing certificates can be found in the article Renewing soon-to-expire certificates on the security server.
Follow the instructions below to remove the certificates.
