Extrasolar terrestrial planets are likely to have compositions unlike anything previously observed. Previous work on this issue has not examined the impact giant planet migration may have on these planetary compositions beyond looking at possible water content. We present 12 simulations incorporating planetary migration. In all cases, migration was found to dramatically alter the planetary composition, acting to broaden the feeding zones and decrease radial variations in composition. Furthermore, migration was found to assist in the delivery of water-rich material to accreting planets.
