Unified CVP 9.0(1) supports migration from Unified CVP 8.0(1) and Unified CVP 8.5(1) releases only. Because Unified
CVP is both a product and a solution, when planning an upgrade it is not enough
to consider only upgrading the Unified CVP product components. The Unified CVP
product relies upon other key components of the Unified CVP solution.
The following components of the Unified CVP solution are not
part of the Unified CVP product but may be used for a complete

Upgrade refers to the general process of moving an
existing installation from an earlier release of Unified CVP to a newer release of Unified CVP, with no change to the platform it is running on or the call control
mechanism it uses. For example, converting a CVP 8.0(1) Call Server to a CVP
8.5(1) Call Server is an upgrade.
Upgrade Unified CVP in stages reduces risks associated with upgrading many products at
one time. To support the multistage upgrade approach, newer versions of Unified
ICM and Unified CM support the older CVP Releases.
you might plan a three-stage process. You upgrade a few components in each
stage such that the stopping point is a fully supported combination of
versions. The desired result is to upgrade the fewest number of components
possible, but to push each of those as far as possible toward the final
version. This method of upgrading reduces the number of variables at each
stage, and at the same time reduces the number of times a given component needs
to be upgraded. After each stage, run regression tests to verify that the
solution is fully operational again. At that time, you may opt to run the
solution in production at that stage for a period of time.
your upgrade plan is in place and you are ready to upgrade, be sure to study
