Migrate to Oracle Linux 8 Tenable Core (Tenable Security Center)

To migrate your Tenable Security Center application to Oracle Linux 8 (OL8), you need to perform two tasks: back up your current data and then restore your backup in the Core user interface with OL8.

Note: Your backup may fail if it occurs while Tenable Security Center processes are active. To avoid backup failures, Tenable recommends that you coordinate your on-demand and scheduled backups around Tenable Security Center freeze windows. For more information about Tenable Security Center freeze windows, see Freeze Windows in the Tenable Security Center User Guide.

Note: If you are migrating to new hardware, review the information in the Requirements section of the Tenable Security Center User Guide.

Before you begin:

  • The application must be the same version on both the source and destination systems. The version matching can be an upgrade on the old system, or a downgrade on the new system. This is required.

    Note: If you get the error message: "This backup was taken from an incompatible version of Tenable Core (tc#) and it cannot be restored on this tc# system. The application version of this backup (v# X.X.X) is not compatible with the version installed on this system (v# X.X.X)," you must manually downgrade the OL8 system using the process found in Downgrade Before Migration.

  • Configure your remote storage host, as described in Configure Storage for Tenable Core Backups.
  • Check your firewall settings and confirm that your computer can access port 8090 on Tenable Core, as described in Access Requirements.

  • For help with issues encountered during the process, refer to the FAQ.

Note: If the hostname on each system is different, a new license file is required.

  1. Log in to Tenable Core via the user interface, as described in Log In to Tenable Core.

    The Tenable Core web user interface page appears.

  2. In the left navigation bar, click Backup/Restore.

    The Backup/Restore page appears.

  3. In the Available Modules section, select the Tenable.sc backup entry.

    Caution: There is also an item in the user interface labeled “Tenable.sc Configuration Only,” this is not the backup to use for this process. This setting does NOT migrate your data and the configuration migration to another machine fails if you select this option.

  4. Click Take Backup Now.

    The Backup in Progress message appears. The message disappears after the system completes the backup.

  1. Log in to Tenable Core via the user interface, as described in Log In to Tenable Core.

  7. Click Restore.

    The system restores your backup to Tenable Core.

    Note: Do not log out of Tenable Core or close your browser until after the Uploading the archive task is complete. If you end your session early, the restore fails.

    When the restore process is complete, a success message appears.

    Tip: If the restore attempt fails, an error message appears with details and remediation instructions. Resolve the errors and click Retry.
