(1) Controller version supports through the most recent release of the Database Agent (2) DB Agent is only compatible up to its corresponding Controller version
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.
