Get Started

Use the following getting started sequence to migrate your entire Tenable Appliance deployment.

To get started with your Tenable Appliance to Tenable Core migration:

If your deployment includes multiple instances of Tenable Appliance, plan your migration sequence.
- You must migrate instances of Tenable Appliance individually to Tenable Core. Tenable does not support a bulk migration for multiple instances.
- If you have multiple Tenable Appliance instances supporting different applications, Tenable recommends migrating in the following order:
  1. All Tenable Appliance + Tenable.sc instances
  2. All Tenable Appliance + Nessus instances
  3. All Tenable Appliance + Nessus Network Monitor instances
  Note: You cannot change applications during the migration process. For example, you can only migrate Nessus on Tenable Appliance to an instance of Tenable Core + Nessus.
  
  If you need to change versions, see Version Requirements.
  
  For more information about migrating multiple instances of Tenable Appliance, see Considerations for Large Deployments.
Choose the migration method you plan to use for each individual instance of Tenable Appliance:
If your deployment includes one or more instances of Tenable Appliance + Tenable.sc, migrate all of your Tenable.sc instances individually:
1. Migrate via the appropriate method: rsync or backup and restore.
2. Perform all necessary post-migration action items.
If your deployment includes one or more instances of Tenable Appliance + Nessus, migrate all of your Nessus instances individually:
1. Migrate via the appropriate method: backup and restore or deploying new instances.
2. Perform all necessary post-migration action items.
If your deployment includes one or more instances of Tenable Appliance + NNM, migrate all of your NNM instances individually:
1. Migrate via the appropriate method: backup and restore or deploying new instances.
2. Perform all necessary post-migration action items.
