I think that you are the parents and you know what is best for your child. No one likes change. I had friends who had to switch their child last year and she was not happy about it, but you know what?! It all worked out. She loves her new school and is very happy. perhaps taking some trips there and showing him all of the cool things he will experience there (they most likely have a website.... check it out and see the current happenings.) are there any summer camp opportunities at the new school? the more familiar it is, the easier the transition may be.
Iff it really doesn't work out, you can always return to the old school but just not giving it a try, you will never know! He may like it 100X more!!!!
