Cisco Unified CallManager Installation and Upgrades

When Cisco first announced that the Cisco CallManager platform would use Microsoft Windows 2000 as a foundation operating system and Microsoft SQL 2000 as a database store, concern arose that the Cisco administrator would require a thorough understanding of these applications to successfully operate a Cisco IP telephony network. Although an understanding of these components can be useful for monitoring and troubleshooting purposes, it is not necessary for Cisco CallManager installation and setup. Cisco has done a fantastic job of "wizardizing" and scripting the complete installation of both Windows 2000 and SQL 2000, hiding any complexity behind a friendly Next button.

The upgrade process of Cisco CallManager is not quite as friendly as a clean install; however, if you keep the potential pitfalls in mind, a Cisco CallManager upgrade can go quite smoothly. This chapter discusses both the clean install and upgrade process of Cisco CallManager.
