I think it depends on your child to be honest, some kids adjust well to change like that and I know my oldest son wouldn't have a problem, my younger son on the other hand it would have been more difficult for. If he's a good student and can make friends easily I think he'll be okay, does he play sports where he could get a connection with the other kids? Will he still be able to be in contact with the other friends? If he can remain in contact and see the older friends periodically I think that's always a bonus, but it will be important to make new friends in the new school as well.
For me personally it wasn't easy adjusting every time we moved and I started a new school. It took me a long time to make friends and by the time I started to feel as though I fit in we moved again. I was very withdrawn. I think the situation probably varies for each individual child.
