This document describes how to migrate user data and, optionally, voice
messages from a Cisco Unity 4.0(5) or later system to Cisco Unity Connection
8.x. In order to complete the migration, you must use COBRAS (Cisco Objected
Backup and Restore Application Suite) to export the user data from the Cisco

few weeks so users can continue to access messages that were left before the

Consolidated Object Backup and Restore Application Suite (COBRAS) is a
set of tools designed to allow administrators to back up all subscribers, call
handlers, interview handlers, name lookup handlers, public distribution lists,
and schedules and to restore some or all of that information onto another Cisco
Unity or Cisco Unity Connection server. COBRAS is specifically designed to
allow for partial restores, restores onto different versions or products than
the version that was backed up, and merges of data from multiple system
backups. This tool does not provide the same functionality as DiRT (Disaster
Recovery Tools) for Unity or the DRS (Disaster Recovery Service) built into
Unity Connection in that it does not do a full backup of the entire database
and it does not restore it all together on a new server.
Note: If the Cisco Unity server is configured as unified messaging,
migrating messages is discouraged because of the following behaviors:
Two copies of migrated messages appear in the Microsoft Exchange
mailbox for each user: the original message and the migrated message that is
synchronized into the Exchange mailbox when a single inbox is
If a user uses Microsoft Outlook to play the original message in
Exchange (the copy that Cisco Unity put into Exchange when the message was
received), the message remains unread in Unity Connection, and the message
waiting indicator remains on. This issue occurs only with migrated messages.
Playing the migrated message (the copy that was synchronized into the Exchange
mailbox by the single inbox feature) or playing messages that are received
after the migration turns off the message waiting indicator on the new
extension as appropriate.
Complete the steps described in this procedure in order to successfully
migrate to Unity Connection 8.x.
Note: These tasks reference detailed instructions in other Unity Connection
documentation as noted. Refer to the appropriate documentation for a successful
If you use the current Cisco Unity server rather than installing a
new server, review the applicable
Unity Connection 8.x Supported Platforms List to determine whether the
server requires replacement hard disks or additional RAM.
Copy or obtain reissued Cisco Unity license files, and obtain a Unity
Connection upgrade license:
Obtain reissued Cisco Unity license files with the MAC address of
the new Cisco Unity Connection server.
Save the reissued license files to a network location. Do not
install the license files now; you do so later in the migration
Obtain a Unity Connection upgrade license, which enables Unity
Connection 8.x and is required for Unity Connection-specific

If you configured a single inbox and if Cisco Unity is configured
as unified messaging, Unity Connection voice messages that are synchronized to
Exchange are saved in the same mailbox in which Cisco Unity voice messages are
now stored. In this case, Cisco recommends that you select the Include
Corporate Email Addresses from Backup for New User Creation check box
When you restore Cisco Unity data on the Unity Connection server,
the Exchange email addresses associated with Cisco Unity users are saved in the
Corporate Email Address field on the User Basics page in Cisco Unity Connection
Administration, which simplifies configuration of a single inbox later in the
