Upgrading a high-availability CDP

This topic describes how to use the GUI installation program to upgrade a configuration distribution peer designated as a high-availability CDP (HA-CDP). During the upgrade, the secondary CDP searches for and uses the primary CDP and the repository configuration settings.

Before you begin

• You must have upgraded the primary CDP.
• If you are using an external authentication service, it must be installed and running.
• The repository and the primary CDP must be running.
• You must have shut down the HA-CDP service and it is recommended that you shut down the services for all peers in your environment (see Starting-and-stopping-product-components-and-services).
• You must have downloaded the installation files from the BMC EPD website.
• You must have completed the HA-CDP-worksheet.
• You must be logged on as an administrator and have administrator rights on the computer where you will upgrade the HA-CDP.
• If you are installing on a Windows computer, ensure that DEP is configured to recognize the installation program executable (Configuring-DEP-on-Windows-computers-before-upgrading).
• Ensure that you have made copies of server.xml and broker-config.xml files and stored them in a safe location (see Backing-up-server-xml-and-broker-config-xml-files).
• If you are upgrading on a Linux computer, run the rngd service to ensure that the system has adequate entropy (Run-the-rngd-service-on-Linux-computers-before-upgrades).
• You must have exited all other programs.

To upgrade an HA-CDP

1. Navigate to the directory where the installation program files are downloaded and start the installation program. 
   
   • Windows: setup.cmd
   • Linux: linux_bao_server_installer_<version>.sh
2. On the splash screen, select the language in which to view the installation program, and click OK. 
3. On the Welcome panel, read the information and click Next.
4. On the license agreement panel, select I agree to the terms of the License Agreement and click Next.
5. On the Installation Type panel, select Upgrade an existing Install and click Next.
6. Using the HA-CDP upgrade worksheet, enter settings in the next screens to upgrade the HA-CDP, including feature selection, destination directory, and HA-CDP connection details. 
7. Click Yes when prompted to restart the server and then click Next.
8. On the Installation Preview panel, review your settings and click Install.
9. When the installation finishes successfully, click Done.

Where to go from here

If you have not already done so, you can upgrade any of the following: 

• Upgrading-an-AP
• Upgrading-an-LAP
• Upgrading-TrueSight-Orchestration-Development-Studio

If you install an embedded version of BMC Remedy Single Sign-On during the upgrade process, after upgrading your TrueSight Orchestration components you must complete the steps in Configuring-a-fail-safe-enterprise-service-bus-after-upgrade.
