I have Cisco ACS appliance 1112-K9 appliance on which ACS 3.3 is running. Since this is an appliance for which SAS is not applicable, please suggest how I can upgrade to Cisco ACS 4.0 without incurring additional cost.
Upgrading acs to 4.x involves cost, so you need to purchase it. With your current ver you should be able to upgrade it to 3.3.4.
You need to open a TAC case inorder to get 3.3.4.
