Device-based licensing has been deprecated and replaced with user-based licenses. Even if you have an older product version (e.g. 5.x-8.x) the legal entitlement you are able to purchase today is no longer device-based. Be sure you understand the implications before placing an order. If you ask "how many DLUs will a UCL Enhanced license get me" you do not understand the new licenses. At the moment the 8.x SKUs will still generate a DLU license since the software didn't become aware of the new license program until 9.0(1). So, you can install the newer license on most older versions. There is no guarantee how long this will remain so start planning your upgrade.
The two cornerstone SKUs are UCL-UCM-LIC-K9 or CUWL-STD-K9 for User Connect or Workspace licensing respectively. Please reach out to your Cisco partner for ordering assistance.
