Field Notice: Upgrading to Microsoft Exchange 2000 or Microsoft Exchange 2003 With a Cisco Unity 2.x System


March 30, 2004


Products Affected

  • Cisco Unity 2.X

Problem Description

If you are using Cisco Unity 2.x, do not upgrade from Microsoft Exchange 5.5 to Microsoft Exchange 2000 or Microsoft Exchange 2003 until you have upgraded Cisco Unity to version 3.1(6) or 4.0. If you attempt the upgrade of Microsoft Exchange without upgrading Cisco Unity you will corrupt the Cisco Unity data and cause Cisco Unity to stop working.

Background

Typically, one of the early tasks in an upgrade from Microsoft Exchange 5.5 to Microsoft Exchange 2000 or 2003 is installing a two-way Microsoft Exchange Active Directory Connector. This replicates data from the Microsoft Exchange 5.5 directory to Active Directory and back again. When data is replicated from Active Directory to the Microsoft Exchange 5.5 directory, where Cisco Unity 2.x subscriber data is stored, a large portion of the Cisco Unity data in the Microsoft Exchange 5.5 directory is corrupted. This causes Cisco Unity to stop working. In addition, the corrupted data cannot be exported from the Cisco Unity 2.x system for import into Cisco Unity 3.1 or 4.0.

Problem Symptoms

Cisco Unity data in the Microsoft Exchange 5.5 directory becomes corrupted causing Cisco Unity to stop working. In addition, the corrupted data cannot be exported from the Cisco Unity 2.x system for import into Cisco Unity 3.1 or 4.0.

Workaround/Solution

For information on upgrading from Cisco Unity 2.x to version 3.1(6) or version 4.0, refer to the Cisco Unity Reconfiguration and Upgrade Guide (With Microsoft Exchange).
