We are planning an upgrade from CUCM 4.2 to CUCM 6.0 in March, 2009. Is it significantly different? Should I try to get some training classes before upgrade? Or are functions esentially the same?
Happy 2009 my friend!
First off, if you can get some training it's always a valuable thing. That being said, functionally, the knowledge that you have gained while working with CUCM 4.x versions will carry across nicely. So you won't be working "in the dark" here. The look and feel is quite different but is not a "show stopper".
If you get some time to play in the "lab" you should be good to go.
Here is one Cisco Press book that is good for CUCM 6.x studies;
Implementing Cisco Unified Communications Manager, Part 1 (CIPT1)
Implementing Cisco Unified Communications Manager, Part 1 (CIPT1), is a CiscoÂ®-authorized, self-paced learning tool for CCVPÂ® foundation learning. This book provides the knowledge necessary to install, configure, and deploy a Cisco Unified Communications solution based on Cisco Unified Communications Manager, the call routing and signaling component of the Cisco Unified Communications solution. By reading this book, you will gain an understanding of deploying a Cisco Unified Communications Manager to support single site, centralized, distributed, and hybrid call processing models.
This book focuses on Cisco Unified Communications Manager Release 6.x. You will learn how to install and configure Cisco Unified Communications Manager, power over Ethernet switches, and gateways using MGCP. You will also learn how to build a scalable dial plan for on-net and off-net calls. The dial plan chapters of the book cover call routing, call coverage, digit manipulation, class of service, and call coverage components. This book will teach you how to implement media resources, LDAP directory integration, and various endpoints including Skinny Client Control Protocol (SCCP) and Session Initiation Protocol (SIP). Cisco Unified Video Advantag endpoint configuration is covered, in addition to, Cisco UnityÂ® voice mail integration and basic voice mail box creation. Various user features are discussed including Presence.
Whether you are preparing for CCVP certification or simply want to gain a better understanding of Cisco Unified Communications Manager fundamentals, you will benefit from the foundation information presented in this book.
Hope this helps!
