Enabling AppControl on Production/Live firewall

[dmn]

Hi

We have some CloudGuard firewalls managed using SmartConsole. We're paying the licensing for the Application Control and URL Filtering features but none of them have been enabled on the Gateways.

What are the implications if I just flick these features on on the gateways? Will they restart? Will the existing policies continue to work fine and I can start adding AppControl/URL policies? etc.

Thank you.
