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.
- BMC Atrium Single Sign-On, the repository, and the primary CDP must be running.
- You must have shut down the HA-CDP service (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 upgrade worksheet for an HA-CDP.
- 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).
- 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-upgrade).
- You must have exited all other programs.
