Hi, 1. it possible to update new list item ID or create new item with defined ID. (original item is deleted in process). There is no OOTB way to do it but you can realize it according to coding, of course the requisites is the ID have to be unique. 2. how can item change folder without creating new item in this folder and deleting old one There is no good solution for this need for this field is system field. Maybe you can turn to coding or third party softwares like SharePoint manager 2007. 3. how can item change content type without creating new item in this folder and deleting old one I have tested this case, but the ID has not changed after changing the content type. Hope it is helpful!Seven
