Plan Your Nessus 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.

Plan Nessus Professional

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

Plan Nessus Manager

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

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.sc stays connected to the instance.

If you change the IP address, you must reconfigure the scanner in Tenable.sc. For more information, see Nessus Scanners in the Tenable.sc User Guide .

Plan Nessus Scanner Managed by Tenable.sc

Most Tenable Appliance + Nessus instances managed by Tenable.sc can be migrated by deploying new instances of Tenable Core. For more information, see Deploy a New Instance.

If you want to preserve an advanced configuration (for example, customized nessusd.rules files or local scan results), you may prefer to migrate via the backup and restore method. For more information, see Perform a Backup and Restore Migration.

Plan Nessus Scanner Managed by Tenable.io

Tenable Appliance + Nessus instances managed by Tenable.io 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.io scanner group or your Tenable.io linking key, you must migrate via the backup and restore method.

    If you want to preserve an advanced configuration (for example, customized nessusd.rules files or local scan results), you may choose to migrate via the backup and restore method.

    For more information, see Perform a Backup and Restore Migration.

  • If you know the appliance's Tenable.io scanner group and your Tenable.io linking key, you may prefer to deploy new instances of Tenable Core instead of migrating. For more information, see Deploy a New Instance.
