Move Earth to a safe distance

Before a billion years are up and our sun expands to become a red giant and incinerates the inner planets we will hopefully have figured out how to move those inner planets, including Earth, out to a safe distance. Why not just save Earth? Venus is to be terraformed. Would moving Venus further away from the sun help to bring about an end to its runaway greenhouse effect? Or is removing the carbon dioxide more important than reducing the planetary temperature?
