After you receive an email from Palo Alto Networks identifying the new product license you're activating, including all your add-ons and capacities, use the activation link to begin the activation process. You can activate and manage all your available licenses, device associations, tenants, and identity and access from Common Services. As existing app instances transition to tenants and tenant service groups you can also use Common Services to manage those as well. After activation or transition, you can find Common Services in the tenant view of the hub or in a variety of ways.
