Port completed game into Cocos 2DX C++

Hi! We have a game developed named Cave Legends in Google play with Papaya Game Engine (action script language), and we would to port it into Cocos 2DX C++.

The problem is the papaya server network not work anymore…and our game now is unplayable because the users are forced to come into the game across the papaya social network…

The only solution for save the 2 years of development is to port the game to a different game engine. We have a C++ background and we think Cocos 2DX fit with our need.

We want to make new interfaces to make the functions of papaya game engine can call the Cocos 2DX functions.

If you wanna take a look this is the link of the game:

Can you give us any advice to port it easily¿?

Greetings.
