[Project Creator] Upgrade to new version?

cocos2d-x C++
#1

Previously I used v2.1.4 for my projects, and it was created using project-creator script.
Currently I want to switch cocos2d-x to v2.2, I have tried moving the “projects” folder from v2.1.4 to v2.2, but it fails to build.

Is there any procedures that need to make in order to upgrade?
Thanks for your help!

I created a same name project with v2.2 script, and add previous “Classes” and “Resourses” into the project. It runs ok. Try it if you didn’t modify the cocos2d-x engine code like me.
