Moving an elementary schooler is not a big deal in my experience. We moved from Houston to Dallas after I finished second grade. I puked the car ride up, but I'm now pretty sure that's because I was sick from my parents feeding us by trying to empty out all the old food in the freezer. I was not a very socially adept kid and the first few days of a new school motivated me to work a lot harder on it, to my long-term benefit, I think.
Sorry if you were behind our car on I-45 that night in summer 1998, though.
