Procedure


Step 1 Click Start > Run. In the Open field, type regedit. Click OK.

The Registry Editor window appears.

Step 2 Browse the folder structure \\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip6\Parameters.

Step 3 Right-click Parameters > New > DWORD (32-bit) Value.

Step 4 Rename New Value #1 as DisabledComponents.

Step 5 Enter the value as 0xffffffff and close the window.

Step 6 Restart the system.

IPv6 is now disabled on Microsoft Windows 2008 Server.


Note To enable IPv6, delete the registry key DisabledComponents and restart the system.

Uploading Required Licenses (Required)

Upload required licenses using the Cisco Unified Application Environment Administration.

See the Getting Started chapter in the Cisco Unified Application Environment Administration Guide, Release 8.5 at the following URL: http://www.cisco.com/en/US/products/ps7058/prod_maintenance_guides_list.html

Migrating Cisco Unified Application Environment to Release 8.5

The earlier versions (2.4, 2.5, 8.0) of Cisco Unified Application Environment were installed in Windows 2003 Server whereas the Cisco Unified Application Environment version 8.5 is installed on the Microsoft Windows 2008 Server (32-bit) SP2 Enterprise or Standard Edition. Hence we have a migration tool which will help your earlier versions of Cisco Unified Application Environment to be migrated to Release 8.5.

The tool has two functions:

Backup

Restore

The Backup feature allows you to back up the databases, the Applications folder, the Audio folder, the Licenses folder, and the Providers folder into a folder created on the C:\. A Stage folder is created on C:\ into which the backed up files and folders are copied. By default, the databases `mce' and `mce_standby' are selected for backup. Upon successful backup, a success message appears.

The Restore feature allows you to restore the databases and all the folders that are copied during the backup process. All the backed up databases will be restored. The contents of the Applications, Audio, Licenses, and Providers folders will also be restored to their original directories. Upon successful restore, a success message appears.

Using the Migration Tool

The section below explains the procedure to use the Migration Tool.

The Migration Tool has three options:

1. Backup
2. Restore
3. Quit

Type the number corresponding to the given options. It takes you to the process you have selected.

In case of invalid inputs, the tool displays a message and prompts you to re-enter the option.

Backup

To perform a backup, follow these steps.

Procedure


Step 1 Type option 1 to enter the CUAE Backup screen.

The backup screen provides a summary of all the tasks to be performed as a part of the backup process.

Step 2 Press any key to start the backup.

The current version of Cisco Unified Application Environment appears on the screen.

Step 3 The tool checks if the Stage folder is already present. If Yes, it overwrites the folder. Else, it creates a new folder.

Step 4 The database backup begins.

The tool displays the list of available databases. By default, the databases `mce' and `mce_standby' are selected for backup.


Note If you want to back up any other database, enter the names of the databases separated by a commas.


Step 5 The Applications, Audio, Licenses, and Providers folders are copied to the C:\Stage folder. A log file is created in C:\.

The backup is now complete. Please copy the C:\Stage folder at a different network location. This stage folder will be required during the restore.

Step 6 Type Y to go back to the main menu or N to exit from the tool.


Restore

Before running the Restore, please ensure that you have the Microsoft Windows 2008 Server 32 bit sp2 installed on the system and Cisco Unified Applications Environment 8.5 installed on it. Please check that all the Cisco Unified Application Server Services are up and running. Now copy the stage folder in the C: driver from the network location. Run the migration tool now.

Procedure


Step 1 Type option 2 to enter the CUAE Restore screen.

Step 2 Press any key to start the restore procedure.

The tool checks for C:\Stage folder in the system. If the folder is not found, it displays an error message. The tool copies the folder from the backup machine (2.4, 2.5 or 8.0) to the system where the restore is to be done.

If the folder is found, restore is initiated.

The tool restores the databases and copies the Applications, Audio, Licenses, and Providers folders back to their original directories.

The restore is now complete.

Step 3 Type Y to reboot the system and then exit from the tool or N to exit without a system reboot.


Log File

A log file, CuaeMigrationLog.log, is created in C:\ that contains all the logs created during the Backup and Restore operations. All the logs appear with a timestamp.

The path of the log file is C:\CuaeMigration.log.

Installing the MDE Components Manually

To install the MDE components manually, follow these steps:

Procedure


Step 1 Download and install Java SDK Version jdk-6u22-windows-i586.exe or latest version to the server on which CUAE is installed.

Step 2 Download and install the Apache Tomcat Installer apache-tomcat-6.0.26.exe on the CUAE Server.

a. In the Tomcat basic configuration options provide HTTP/1.1 Connector Port as 8020.

b. Go to C:\Program Files\Apache Software Foundation\Tomcat 6.0\webapps.

Place the file mde-messaging-service.war in the webapps folder.


Note Extract mde-messaging-service.war from the MDE.zip file provided with the Installers.


c. Execute the following:

C:\Program Files\Apache Software Foundation\Tomcat 6.0\bin\tomcat6.exe

d. Go to C:\Program Files\Apache Software Foundation\Tomcat 6.0\webapps\mde-messaging-service\WEB-INF

Open the web.xml file to edit. And change the following parameters.

1. Provide the CUAE IP in the param-value for MESSAGING-SERVER-IP.

2. Provide the value 8020 in the param-value for MESSAGING-SERVER-PORT.

Save and exit the web.xml file.

e. Go to C:\Program Files\Apache Software Foundation\Tomcat 6.0\webapps\mde-messaging-service\WEB-INF\classes

Open the file hibernate.cfg.xml and edit the CUAE Server IP address and port number in the line as given below:

<property name=connection.url>jdbc:mysql://CUAE IP:3306/mdepdb</property>

In the same file, also verify that password used for root during installation process is same.

Step 3 For MDE Dispatcher Service, perform the following operations:

a. Copy the folder mde-dispatcher-service from the MDE.zip folder provided with the installers and paste it in the C drive location of the CUAE Server.

b. Edit the file runMDEService.bat to assign CUAE Server IP address at two locations in the file.

Step 4 For CUAE MDE Database Configuration setup, perform the following operations:

a. Login to CUAE DB using command: mysql -u root -p

b. Enter the DB password.

c. Enter the command: use mdepdb;

d. Enter the command: Source /filepath/mdepdb.sql


Note Extract mdepdb.sql from the MDE.zip file. Copy the mdepdb.sql file in the CUAE Server. Filepath is the location where the mdepdb.sql file is copied.


e. Enter the command:

GRANT ALL PRIVILEGES *.* TO root@CUAE IP IDENTIFIED BY `metreos'


Note Where root is the mysql's root user and metreos is the root password.


Step 5 To run the MDE Dispatcher Service and MDE Messaging Server.

a. Login to CUAE Server > Command Prompt > C:\mde-dispatcher-service\runMDEService.bat

b. Command Prompt > C:\Program Files\Apache Software Foundation\Tomcat 6.0\bin\tomcat6.exe

Configuring the MDE Provider in CUAE Administrator Page

To configure the MDE Provider in Cisco Unified Application Environment Administration, follow these steps:

Procedure


Step 1 Go to Plugins > List Plugins.

Step 2 Select MDE Provider.

Step 3 Enter the CUAE IP address.

Step 4 In MDE Database Port Enter the value as - 3306

Step 5 IP address of Dispatcher as the CUAE IP address.

Remaining value remains the same.
