Plan Your Tenable Nessus Network Monitor Appliance Migration

The Tenable Appliance to Tenable Core migration process varies depending on your current Tenable Appliance deployment and your desired Tenable Core deployment. To confirm you meet the application version requirements, see Version Requirements.

Tenable Nessus Network Monitor Standalone Instance

Tenable Appliance + Tenable Nessus Network Monitor standalone instances can migrate to Tenable Core via the backup and restore method. For more information, see Perform a Backup and Restore Migration.

Tenable Nessus Network Monitor Instance Linked to Industrial Security

Industrial Security is end-of-life (EOL). For information about EOL dates and policies for Tenable products, see the Tenable Software Release Lifecycle Matrix and Policy.

Tenable Appliance + Tenable Nessus Network Monitor instances linked to Industrial Security can migrate to Tenable Core via the backup and restore method. For more information, see Perform a Backup and Restore Migration.

Tenable Nessus Network Monitor Instance Linked to Tenable Security Center

Tenable Appliance + Tenable Nessus Network Monitor instances managed by Tenable Security Center can be migrated by the backup and restore method or by deploying new instances of Tenable Core, depending on the needs of your organization.

  • If your highest priority is to retain your Tenable Nessus Network Monitor instance configurations, you must migrate via the backup and restore method. For more information, see Perform a Backup and Restore Migration.

  • If you prefer a faster migration and you are willing to reconfigure your Tenable Nessus Network Monitor instance configurations after migration, you may prefer to deploy new instances of Tenable Core instead of migrating. For more information, see Deploy a New Instance.

    Note: Tenable recommends retaining the same IP address before and after your migration. If you use the same IP address for your appliance and for Tenable Core, Tenable Security Center stays connected to the instance.

    If you change the IP address, you must reconfigure the Tenable Nessus Network Monitor in Tenable Security Center.

Tenable Nessus Network Monitor Instance Linked to Tenable Vulnerability Management

Tenable Appliance + Tenable Nessus Network Monitor instances managed by Tenable Vulnerability Management can be migrated by the backup and restore method or by deploying new instances of Tenable Core, depending on the needs of your organization.

  • If you do not know the appliance's Tenable Vulnerability Management scanner group or your Tenable Vulnerability Management linking key, you must migrate via the backup and restore method. For more information, see Perform a Backup and Restore Migration.
  • If you know the appliance's Tenable Vulnerability Management scanner group and your Tenable Vulnerability Management linking key, you may prefer to deploy new instances of Tenable Core instead of migrating. For more information, see Deploy a New Instance.
