Chapter 9 Migrating to Cisco Unity from Another Voice-Messaging System

•The supporting infrastructure (for example, message store servers), whether dedicated to

Cisco Unity or being used by Cisco Unity, must be evaluated for availability and responsiveness. This can be accomplished by helping a customer understand the dependencies Cisco Unity has on the infrastructure, and how Cisco Unity performance or functionality can be affected by loss of connectivity to any of the external dependencies. Any problem areas should be addressed prior to installation of Cisco Unity. Cisco Unity will expose any deficiencies on the network, due to the way it uses the resources available on the network.

When the Cisco Unity design is finalized and verified through lab qualification, Cisco Unity functionality should also be tested before cutover by running a simulated load test and by running application test plans.
