Migration history for a selection of models described in Table 1 to highlight the different possible dynamical evolution of the embedded planets. The panels show, from top to bottom, the evolution of: the semi-major axis, a, of the outer and inner planet, their eccentricities, e, and their period ratio. The release time of the planets is marked by the vertical dotted line. Most prominent is the occurrence of fast outward migration (migration jump) for model M9-3 (blue) between 60 and 80 kyr, and a double orbit swap at 110 kyr followed by a migration jump for model M9-4.5. At the time of the double orbit swap at t ~ 110 kyr, e_in = 0.38 and e_out = 0.58. They are cut out to increase the visibility of the rest of the data.
