Consider the following frequently asked questions when planning your upgrade.
For more information about local machine, Nessus, and Tenable.io requirements, see Requirements.
For information on what data is transferred from Nessus to Tenable.io, see Migrated Data.
Tenable™ recommends backing up Nessus regularly as a deployment best practice, but the upgrade assistant does not remove any data from Nessus. Your Nessus deployment continues running as configured.
After you upgrade from Nessus to Tenable.io, Nessus becomes a managed scanner. You can no longer use that instance of Nessus as a standalone scanner, but you can log in and see scan history for the upgraded scans.
Tenable™ recommends running the upgrade assistant only once, from your existing Nessus deployment to a Tenable.io instance. Once you upgrade your data from Nessus to Tenable.io, Nessus becomes a managed scanner, so the option to upgrade again is no longer available.
The upgrade assistant is currently only available via the Nessus Professional user interface.
Upgrade time varies depending on the number and complexity of your scan policies.
