To make sure you complete all the tasks necessary for upgrading your Database Agents after a release, we recommend following the instructions in our upgrade checklist. This guide is not release-specific and can be referenced for any release.
Tip! Before upgrading, we recommend completing two backups:
Backup your previous installation of the Controller.
Backup the <db_agent_home> directory so you can revert to the previous installation if required. To maintain the same configuration information, you will also need the <db_agent_home>\conf\controller-info.xml file.
If you are upgrading both the Controller and agents, upgrade the Controller before upgrading the agents.
