This is a bit OT, but not terribly so.
Go for it. I uprooted my daughter in seventh grade, and while it wasn't great for her socially, academically it has been fantastic for her. She starts high school in the fall and is looking forward to it.
I was just in NC on Monday, looking at a college with my son. The school was INCREDIBLE. The NC state system is awesome. Heck, I was willing to move there myself.
I'm in CT, outside NYC. While the population here is huge, the men are sooooo picky that an average looking/weight 45 year old woman with two kids is soooo not what the men want. They want Barbie Dolls who look like they're 24. It's very discouraging.
Again, I say, go for it.
