Once you've lived through the ANZOBJCVN to 6.1, the code should run on 7.1
However, software vendors have a "bad" habit of letting their code check to see what version of the OS you're running on... and stop running if you're on an unlicensed version. ):
Do software vendors charge 'extra' if you jump to 7.1 without a stop at 6.1??
