How certificates are deployed on hosts during upgrades
During a NetBackup 8.1 upgrade, NetBackup deploys host ID-based certificates before the upgrade. If the certificates cannot be deployed, you can terminate the upgrade process. The upgrade script retains the existing NetBackup setup that you can use.
If you have upgraded NetBackup from 8.0 to 8.1, host ID-based certificates may already be present on the hosts. In such a case, certificates are not deployed during the upgrade process.
Certificates are not deployed during the upgrade process, if the software is upgraded using a utility (that downloads and installs security updates and software patches). You need to manually deploy the certificates.
