Upgrading to Unified CVP Release 4.0

Unified CVP supports upgrade of its product components from ISN Release 2.1(0), CVP Release
3.0(0), and CVP Release 3.1(0) to Unified CVP 4.0. When planning an upgrade, however, it is
not enough to consider only upgrading the CVP product components. There are dependencies
all across the solution for operating systems, Cisco software such as ICM Enterprise Edition,
Cisco Unified CallManager, and IOS, and third-party software. In addition, there are changes
in Unified CVP Release 4.0 that may necessitate migrating existing Unified CVP installations
to different deployment models.

This chapter provides the following information related to upgrading to Unified CVP Release
4.0.
