According to the documentation of is_isomorphic, you can use the argument certificate=True:

sage: G = Graph([(0,1),(1,2)])
sage: H = Graph([(8,9), (9,10)])
sage: G.is_isomorphic(H)
True
sage: G.is_isomorphic(H, certificate=True)
(True, {0: 10, 1: 9, 2: 8})


If the automorphism group of G is non trivial, there are more than one such map. You can deduce all of them from the automorphism group of G:

sage: G.automorphism_group()
Permutation Group with generators [(0,2)]
