Porting from HP-UX to AIX

I am orignally a VC++ programmer, this is the my post in UNIX form.

I have an existing source code, that was developed in old HP-UX system, the objective is to make it work on new AIX system.

It does'nt appear that AIX has the necessary libraries or even run the application if its precompiled under HP-LX. So can someone provide me detailed steps for porting this application from HP-UX to AIX?

Thanks in Advance
