from your posts it looks that GSU is safety that your child choose for CS. There is no way to transfer to CS with any transfer path unless your child is legacy and fall under Conditional Transfer umbrella (parent, grandparent, or sibling).
If your child is good at CS, my suggestion is to go through Kennesaw State University Engineering program and apply through Engineering path to Computer Engineering. (No opportunity to change major.) The only other option is taking GAP year and apply to different set of schools next year.
