You could deep clone (brand new vertices/edges/properties) of tinkergraph
by using detachment. Do something like this:
```text
gremlin> graph1 = TinkerFactory.createModern()
==>tinkergraph[vertices:6 edges:6]
gremlin> graph2 = TinkerGraph.open()
==>tinkergraph[vertices:0 edges:0]
gremlin> graph1.vertices().forEachRemaining { v ->
DetachedFactory.detach(v, true).attach(Attachable.Method.create(graph2)) }
gremlin> graph2
==>tinkergraph[vertices:6 edges:0]
gremlin> graph1.edges().forEachRemaining { e -> DetachedFactory.detach(e,
true).attach(Attachable.Method.create(graph2)) }
gremlin> graph2
==>tinkergraph[vertices:6 edges:6]
```
I think that gets it, right?
