I think all you have to do is goto the "my games" folder Halo probably made inside "My Documents" on installation on your old computer, and copy the "Halo" folder into the "my games" folder of your new computer. I think it works. But if your computers have different versions of Halo, all your checkpoints may be reset to the beginning of their respective levels.
That should work, I did something similar when I wanted to backup some checkpoints.
