Check the following recipe published in Gremlin docs for moving an edge.
The "marko" vertex contains a "knows" edge to the "vadas" vertex. The following code shows how to "move" that edge to the "peter" vertex in a single traversal:
g.V().has('name','marko').as('a').
outE('knows').as('e1').filter(inV().has('name','vadas')).
V().has('name','peter').
addE('knows').from('a').as('e2').
sideEffect(select('e1').properties().
unfold().as('p').
select('e2').
property(select('p').key(), select('p').value())).
select('e1').drop()
