Thank you for contacting Syncfusion support.
Query #1: I wonder if it would be possible to implement kanban-like workflow rules when using multiple drag-drop listboxes?
We have checked your query. We would like to suggest you that you can able to drag and drop within multiple listboxes by using scope property of Listbox with same name. We have prepared a sample based on your requirement. Please refer the sample link below
Query #2: if it's possible to upgrade remotely as soon as you drop a listbox
Could you please share more details about `upgrade remotely after drop`, So that we can work on this and provide you a better solution quickly.
