Damage dice progression strong jaw

[Atalius]

When using strong jaw does 1D4 damage go to 2D6 and 1D6 damage go to 2D8? I am basing this off of the damage dice progression chart, or would I use the natural attacks chart found directly in the spell Strong jaw.

1d4>1d8
1d6>2d6

Lady-J is correct. The best reference for these things is this FAQ.
