[Koha] Sending Overdue Notices After Import from Follett

Hello! We recently moved to Koha 3.12 from Follett Circulation Plus. When we imported the data, we also pulled in the circulation data from Follett. There were roughly 120 overdue items pulled into Koha from Follett. How do I trigger overdue notices to go out for these overdue items pulled in from Follett? I've researched this and haven't found any answers. Thanks! -- Sheldon Harris, M. Ed. Systems Administrator College of Education Idaho State University Phone: (208) 282-4302
