Downgrade Before an Rsync Migration

Required Tenable Core User Role: Administrator with reuse my password for privileged tasks enabled

If your Tenable Security Center version on Tenable Core is later than your version on Tenable Appliance, you must downgrade Tenable Core to your Tenable Appliance application version before performing an Rsync migration.

The downgrade process is different for online and offline Tenable Core migration environments.

Before you begin:

  • If you are migrating in an offline (air-gapped) environment, manually download the RPM for the version of the application being migrated from the Tenable downloads page.

To perform a downgrade in an online migration environment:

  1. In Tenable Core, log in to the shell via the Terminal page or the console.

  2. Run the following command to begin the downgrade:

    pkexec /usr/libexec/tenablecore/backup/applicationDowngrade.sh SecurityCenter

    Caution: Running the downgrade command launches a script that completely removes the current version (all data). Then, the lower version that you select during the script is installed.

    A version prompt appears.

  3. Press the number next to your Tenable Appliance application version.

  4. Press Enter.

    A confirmation prompt appears.

  5. Press y to confirm the downgrade details.

    The downgrade begins. When the downgrade finishes, the system displays a Complete! message.

To perform a downgrade in an offline migration environment:

  1. In Tenable Core, log in to the shell via the Terminal page or the console.

  2. Run the following command to begin the downgrade:

    pkexec /usr/libexec/tenablecore/backup/applicationDowngrade.sh -r <path to the .rpm file you downloaded>

    The downgrade begins. When the downgrade finishes, the system displays a Complete! message.
