You cannot upgrade directly from one Edition of Cisco Unified Attendant Console to another: a full re-installation and a new license are required.
If you upgrade the Cisco Unified Attendant Console server you also need to upgrade the Cisco Unified Attendant Console. If you do not, differences between the databases may cause inconsistent system performance.
IIS must be installed and activated before installing Cisco Unified Attendant Console.
If you have a Microsoft Windows network that uses DHCP, you must allocate a static IP address to the Cisco Unified Attendant Console server machine.
Access to the Cisco Unified Attendant Console server is not supported at any time via Remote Desktop (RDP), Terminal Services (TS) or any other session-based application. These applications can cause TAPI/TSP and Wave Driver instability. Only local or VNC connection is supported.
Once a system is fully licensed you cannot apply temporary licenses for additional seats. You must wait for the order process to be fulfilled by Cisco before you can add additional seats to an already licensed server.

CUDAC/CUBAC/CUEAC seat license
The licensing appears to follow a concurrent connection model. Which suggests, that you only need one seat license in your scenario.
You must order a Cisco Unified Business Attendant Console license for each concurrent operator login. A maximum of six concurrent operator client logins are supported per Cisco Unified Business Attendant Console server. Example: If you need six attendant consoles logged into the server at the same time, you should order six licenses.
