Scenarios

Cisco Unified Contact Center Enterprise (Unified CCE) is supported only in a virtualized environment.


Note

This Cisco Packaged Contact Center Enterprise Installation and Upgrade Guide provides the Install and Upgrade details and procedures for both 12.5(1) release and 12.5(2) maintenance release.

Installation Scenario

The Unified CCE components are supported on the following platform in 12.5(1) release.

  • Microsoft Windows Server 2016 and Microsoft SQL Server 2017

The CCE components are supported on the following platforms in 12.5(2) release.

  • Microsoft Windows Server 2016 and Microsoft SQL Server 2017

  • Microsoft Windows Server 2019 and Microsoft SQL Server 2019


Note
The cross combination of platforms is not supported. For example, Windows Server 2016 with SQL Server 2019 or Windows Server 2019 with SQL Server 2017.

In a virtualized environment, you can run Unified CCE on a VMware ESXi platform. Run the virtual machines (VMs) on Cisco Unified Computing System (UCS) C-series servers, or equivalent third-party servers.

Install the Unified CCE components after you configure the VMs.

You can use the OVA template to deploy the VMs before beginning with the installation of Unified CCE components.


Note

Deploying VM with Guest Operating System ‘Microsoft Windows Server 2019’ on ESXi 7.0 using CCE OVA template displays a warning message, “The configured guest OS (Microsoft Windows Server 2016 or later (64-bit)) for this virtual machine does not match the guest that is currently running (Microsoft Windows Server 2019 (64-bit)). You should specify the correct guest OS to allow for guest-specific optimization”. This warning message is informational only and has no detrimental effect on the system. This warning message is displayed only once and can be ignored.

The Unified CCE 12.5(2) installer is available as an add-on release to Unified CCE 12.5(1). Therefore, complete the installation of the base Unified CCE 12.5(1) before applying Unified CCE 12.5(2).


Note

During Unified CCE installation on Windows Server 2019 and SQL Server 2019, SQL Server Security Hardening optional configuration should not be selected as part of the installation steps. Unified CCE services should be started only after installing Unified CCE 12.5(2) for Windows Server 2019 and SQL Server 2019 support. The SQL Security Hardening can be applied post installation using the Security Wizard tool.
