Calendar - Dragging Events to another component

Hey all,
I want to drag events I created inside my calendar component from my calendar to another component, in this case to another calendar component. I´ve found examples to drag rows of a table to a calendar but not the other direction. 
I can move my events inside one calendar while using the BasicEventMoveHandler. But additionally I want to move them to a second calendar.
Could someone please give me a hint how I make a single calendar- event draggable to move it away from my calendar?

Best regards and thanks for your help in advance
Michael
