Preparing for upgrade
Ensure that the steps in this section have been completed before upgrading from all TrueSight Orchestration Platform versions.
- Backing up server.xml and broker-config.xml files
- Configuring DEP on Windows computers before upgrading
- Run the rngd service on Linux computers before upgrades
Note
If you manually configure values in some files after installing or upgrading the product, you must update the corresponding values in the PlatformInstalledConfiguration.xml file in the AO_HOME directory.
During future upgrades, the installer reads the PlatformInstalledConfiguration.xml file to populate installation wizard screens with those values. To ensure that the values used to populate the install wizard screens are valid for your environment, keep the values updated in the PlatformInstalledConfiguration.xml file.
If you change values in the following files, ensure that you locate the original values in the AO_HOME/ PlatformInstalledConfiguration.xml file and replace them with the new values:
- AO_HOME/tomcat/conf/server.xml – Includes values, such as port number, protocol type, and host name
- AO_HOME/tomcat/conf/context.xml – Includes values, such as port number, protocol type, and host name
- AO_HOM/config/authentication.xml – For Platform version 7.9 and later, this file contains Remedy Single Sign-On values for realm, URL, and Remedy SSO type (embedded or external)
Where to go from here
