Hi
You need to buy license for IOS with Crypto feature set as you are planning to upgrade.
Please note:
Updates = No license
Upgrades = License
-------------
Licensing
--------------
Customers license the right to use Cisco intellectual property (software) from Cisco. When you purchase hardware, you also purchase the software and the license to use it. Hardware arrives with licensed software. When you need a different feature set, you need to purchase the license for it
-----------------
SMARTnet Licensing
------------------
An individual feature license must be purchased for the specific Cisco IOS Software image for each router on which the image will be used. For example, customers who have purchased a Cisco IOS Software IP image along with their Cisco equipment, and subsequently wish to use Cisco IOS Software IP Plus, must purchase a feature license for Cisco IOS Software IP Plus. The additional feature license will entitle them to use the Cisco IOS Software IP Plus image.
-------------------------
Licensing Best Practices
-------------------------
•Pay an additional fee to upgrade to a new feature set-upgrades require new license. No additional fee is due when the feature set stays the same-updates require no new license
•Charge customers for upgrade or special feature licenses
•Resell software (and license to use) that runs on the Cisco hardware when they resell the hardware.
