You can import the rule sets of the web policy that you have configured with Secure Web Gateway (On Prem) to a cloud environment, where you can continue to work on these rule sets with Secure Web Gateway (Cloud).
On the user interface for Secure Web Gateway, place your mouse pointer over the settings icon in the top right corner, then select Infrastructure > Web Gateway Setup from the drop-down menus.
On the setup main page, scroll down to Import On-prem Policy and click Start Importing.
On the page that appears, work with the options that are provided to import a file with a backup of your on-prem web policy.
When the import has completed, you can work on the rules and rule sets that are now available using Secure Web Gateway (Cloud) options.
