им обеим надо задать одинаковый TYPE, чтобы они обе могли принимать айтемы с одинаковым типом
<Droppable droppableId="droppable2" type="LIST">
....
onDragEnd(result) {
....
console.log(result.destination.droppableId, result);
if(result.destination.droppableId === 'droppable2') {
// переместить в this.state.items2, или еще как-нибудь отметить позицию айтема
}
.....
}

type: A TypeId(string) that can be used to simply accept only the specified class of <Draggable />. <Draggable />s always inherit type from the <Droppable /> they are defined in.
For example, if you use the type PERSON then it will only allow <Draggable />s of type PERSON to be dropped on itself.
<Draggable />s of type TASK would not be able to be dropped on a <Droppable /> with type PERSON.
If no type is provided, it will be set to 'DEFAULT'.
