Recurring Calendar Events are coming over as a multiple items instead of reoccuring
説明
Some events that are set with repeat options (and field names) as Calendar Entry do not come over as a single list item with recurrence. Each date in the recurrence comes over as a new item.
原因
If the calendar's are R4 calendars the tool does not support this.
対策
You will have to upgrade the calendars to a newer format to migrate the recurring events.
