Before You Upgrade

Note: A basic understanding of Linux is assumed throughout the installation, upgrade, and removal processes.

SecurityCenter Version Requirements

For more information, see the SecurityCenter Release Notes.

Java Version Requirements

If the Oracle Java JRE or OpenJDK is not installed, SecurityCenter displays the following warning:

[WARNING] SecurityCenter has determined that Oracle Java JRE and OpenJDK is not installed. One of two must be installed for SecurityCenter reporting to function properly.

You must install the latest version of Oracle Java JRE or OpenJDK to take full advantage of SecurityCenter reporting.

Halt or Complete Running Jobs

Tenable recommends stopping all running SecurityCenter processes before beginning an upgrade. If processes are running (e.g., Nessus scans), SecurityCenter displays the following message along with the related process names and their PIDs:

SecurityCenter has determined that the following jobs are still running. Please wait a few minutes before performing the upgrade again. This will allow the running jobs to complete their tasks.

Stop the processes manually or retry the upgrade after the processes complete.

Perform a SecurityCenter Backup

For more information, see Backup and Restore.

Rename Mount Point

If the existing /opt/sc4 or /opt/sc directory is or contains a mount point to another location it must be updated. During the rpm upgrade process, a message appears with information about the discovered mount point and instruct you to contact Tenable Support for a mount point tool to help identify and migrate your mount points for the upgrade to continue.

Reconfigure SecurityCenter 5.4 CoSign Authentication

CoSign is not a supported authentication method in SecurityCenter 5.5.x. If your SecurityCenter 5.4.x installation uses CoSign servers for authentication, you must reconfigure your SecurityCenter 5.4.x to use an authentication method supported in SecurityCenter 5.5.x.
