We upgraded and re-configured two existing ASA5520 platforms in order to provide an SSL VPN solution for one of our customers.
The customer opted to deploy AnyConnect Essentials the functionality / features they required for day one were catered for in the Essentials license and budget constraints meant Premium licensing could not be included in the original deployment.
The licenses added to the system were:
L-ASA-AC-E-5520= AnyConnect Essentials VPN License - ASA 5520 (750 Users)
ASA-AC-M-5520 AnyConnect Mobile - ASA 5520 (req. Essentials or Premium)
The customer is now seeing a growing number of mobile devices and wishes to support the BYOD culture growing within the business; as a result we now need to use features available in AnyConnect Premium. I am aware from reading the following document [https://supportforums.cisco.com/docs/DOC-1361#Q_Does_the_AnyConnect_mobile_license_work_with_both_AnyConnect_Essentials_and_Premium_clients] that AnyConnect Essentials and Premium licenses cannot co-exist on an ASA; I need to ensure we purchase the appropriate upgrade for the customer.
Is there an SKU to upgrade / migrate an existing Essentials deployment to Premium? I've reviewed the licensing guide and price list but cannot find a method which enables this transition.
