After you upgrade the agent, existing jobs on the agent computer are not automatically upgraded to use the latest Knowledge Script functionality. Upgrading jobs to use the latest Knowledge Script version allows the jobs to take advantage of the latest Knowledge Script logic while maintaining existing job parameter values. Any associated graph data and event information are also retained if they have not changed. If the latest version of a Knowledge Script includes new parameters, for example, to create different events or data streams, the default values for the new parameters in the latest Knowledge Script are used.
For more information about upgrading jobs after you upgrade an agent, see Section 5.0, Upgrading Ad Hoc Jobs.
