What happens during a rerun of an activity plan when there are already published occurrences?

During a rerun when there are already published occurrences:

• There will be no changes in already suggested occurrence or sessions on rerun.
• Only unscheduled or new attendees can be included in an already suggested session (if the minimum or maximum group size configuration permits) or a new session could be suggested based on the configuration of an activity plan (maximum number of sessions).
• Future occurrences are suggested based on the recurrence end configuration for recurring activity.
