Replacing a Cisco Unity Server Without Failover
The procedure in this section requires that you use the Cisco Unity Disaster Recovery tools (DiRT), which are supported for Domino with Cisco Unity 4.0(3) and later only. To replace a Cisco Unity server that is running version 4.0(2) or earlier, first upgrade the existing server to the shipping version, then replace the server by doing the procedure in this section.
Caution You must install the exact version of Cisco Unity on the replacement server as the version that you back up on the existing server. The Disaster Recovery Restore tool can restore data only to the exact version of Cisco Unity that was backed up.
Caution Do the procedure only if the Cisco Unity server is the only server in the domain or if it is a member server. If the Cisco Unity server is the domain controller and it is not the only server in the domain, refer to Microsoft documentation for information on installing Active Directory on another server in the domain, transferring roles from the Cisco Unity server to the new domain controller, and other applicable tasks before you replace the Cisco Unity server.
To Replace a Cisco Unity Server Without Failover
Step 1 Confirm that you have all of the disks necessary to reinstall the version of Cisco Unity currently installed on the Cisco Unity server. When you use DiRT to back up and restore Cisco Unity data, you must restore to the same version of Cisco Unity that you backed up.
Step 2 Cisco Unity 4.x licenses are associated with the MAC address on the network interface card (NIC). Get updated license files that reference the MAC address of the NIC in the new server.
For information on getting updated license files, refer to White Paper: Licensing for Cisco Unity (All Versions) at http://www.cisco.com/univercd/cc/td/doc/product/voice/c_unity/whitpapr/licenses.htm.
Step 3 Download the latest versions of the following applications:
•The Cisco Unity Directory Walker (DbWalker) utility. The version for Cisco Unity 4.x is available at http://ciscounitytools.com/App_DirectoryWalker4.htm. The version for Cisco Unity 3.1(x) is available at http://ciscounitytools.com/App_DirectoryWalker3.htm.
•The Cisco Unity Disaster Recovery Backup tool and Disaster Recovery Restore tool, available at http://ciscounitytools.com/App_DisasterRecoveryTools.htm.
Step 4 On the Cisco Unity server, install the versions of DbWalker and the Disaster Recovery Backup tool that you downloaded in Step 3.
Step 5 Run DbWalker, and correct all errors that the utility finds. Refer to DbWalker Help for detailed instructions on running the utility and on correcting errors in the database. (The Help file, DbWalker.htm, is in the same directory as DbWalker.exe.)
Step 6 Back up Cisco Unity data by using the Disaster Recovery Backup tool. Refer to DiRT Help for detailed instructions. (The Help file, UnityDisasterRecovery.htm, is in the same directory as UnityDisasterRecoveryBackup.exe.)
Caution Follow Help carefully. DiRT includes a variety of options that you must understand to use the tools successfully. In addition, the account you are logged on as when you back up Cisco Unity data must have sufficient permissions or the backup will fail.
Step 7 If the existing Cisco Unity server is integrated with a circuit-switched phone system and you want to move the voice cards to the replacement server, shut down the existing server.
If the replacement server will be integrated with Cisco CallManager or if you are installing new voice cards, the existing Cisco Unity server can continue taking calls until Step 11.
Step 8 Remove voice cards from the existing server, if applicable.
Step 9 Install hardware, if applicable, and software on the replacement server by following the instructions in the applicable Cisco Unity installation guide for your configuration at http://www.cisco.com/en/US/products/sw/voicesw/ps2237/prod_installation_guides_list.html.
Caution You must install the same version of Cisco Unity that was installed on the old server. Otherwise, the Disaster Recovery Restore tool cannot restore the data that you backed up earlier in this procedure.
Note the following:
•When you configure Windows, if there is more than one Cisco Unity server in the Active Directory forest, give each Cisco Unity server a name that is unique in the first 14 characters, or Cisco Unity will have problems communicating with the Active Directory accounts created by Cisco Unity. For example, the following names would cause communication problems: CiscoUnitySrvr1 and CiscoUnitySrvr2.
•If you are not replacing the phone system, you can skip the task on setting up or programming the phone system.
•If you are installing Cisco Unity 4.2(1) or later, and if you are making the Cisco Unity server a member server in an existing domain, add the server to a Windows 2000 Server domain or Windows Server 2003 domain. Beginning with Cisco Unity 4.2(1), adding the Cisco Unity server to a Windows NT domain is not supported.
Step 10 If the old Cisco Unity server is still running, shut it down.
Step 11 Disconnect the old Cisco Unity server from the network, and connect the replacement server to the network.
Step 12 On the replacement server, install the version of the Disaster Recovery Restore tool that you downloaded in Step 3.
Step 13 Restore Cisco Unity data by using the Disaster Recovery Restore tool and the backup that you made earlier. Refer to DiRT Help for detailed instructions. (The Help file, UnityDisasterRecovery.htm, is in the same directory as UnityDisasterRecoveryRestore.exe.)
Caution Follow Help carefully. DiRT includes a variety of options that you must understand to use the tools successfully.
Step 14 Reapply any non-Cisco Unity custom registry settings. (DiRT backs up and restores Cisco Unity registry settings.)
Replacing Only the Primary Server in a Pair of Failover Servers
This section describes how to replace the computer on which the primary Cisco Unity server is installed. The replacement primary server keeps the IP address and server name that the original server had.
Caution Changes made to the Cisco Unity system (for example, recording new greetings or making subscriber changes) while the secondary server is active and the primary server is off line are not replicated to the primary server.
Caution An interruption of the voice messaging service occurs in the final procedure of replacing the primary server. During this time, callers and subscribers will not be able to record or listen to voice messages.
The following items are required to replace the primary server:
•The latest versions of the following applications:
–The Cisco Unity Directory Walker (DbWalker) utility, available at http://ciscounitytools.com/App_DirectoryWalker4.htm.

When converting a Cisco Unity failover server to another purpose for which Cisco Unity failover is not needed, it is necessary to change a number of settings for the Cisco Unity system.
To convert a primary or secondary Cisco Unity server to a Cisco Unity server without failover, see the applicable section in this chapter:
•Converting a Secondary Server to a 60-Day Cisco Unity Server Without a Primary Server
•Converting a Secondary Server to a Permanent Regular Cisco Unity Server Without Failover
•Converting a Primary Server to a Permanent Regular Cisco Unity Server Without Failover
To convert a primary or secondary Cisco Unity server to a server for another application, follow the installation instructions for the application.
Converting a Secondary Server to a 60-Day Cisco Unity Server Without a Primary Server
When operating without the primary server, the secondary server answers calls for 60 days after the last time that it was able to contact the primary server, provided the secondary server has contacted the primary server at least once.
Do the following three procedures in the order listed.
