Export a Policy
You can export an existing scan policy in Tenable Nessus as a .nessus file and import it into a different Tenable Nessus installation. You can then view and modify the configuration settings for the imported policy.
To import a policy:
In the top navigation bar, click Scans.
The My Scans page appears.
In the left navigation bar, click Policies.
The Policies page appears.
In the row of the policy that you want to export, click .
The policy downloads to your machine as a .nessus file. You can import the policy into a different Tenable Nessus installation, or you can save it for future use.
