When an escalation path is disabled, you can modify the path filter and add or remove levels. If you disable all of the paths in an escalation policy, you can edit the escalation policy filter.
Disabling a path cancels the escalation of any notifications along the path. If you want to modify a path or policy but do not want to cancel any scheduled notifications, you can retire the path or paths instead. This prevents new notifications from joining the path but allows scheduled notifications to continue to escalate. “Retiring an escalation path” on page 173 includes information on retiring a path.
