Backward Compatibility?

If I develop an application on Solaris 7 using C++5.0 (in 32 bit mode). What do to tell a customer that uses that application about what the minimum requirements are with regard to the version of Solaris they need to be running on their system. What I mean is will the application that I build run correctly (with regard to the environment) on a customer system running Solaris 2.6 (2.51) etc.. (I've found statements about applications developed on Solaris 2.6 running on Solaris 7, but nothing about the reverse case.)

    Reverse case is not guaranteed to work. In many cases it works. Even if it works it will not be supported by Sun. Best thing to do is to compile application on lowest Solaris version(where it has to run i.e 2.5.1 ) with latest patches/libraries and then port on higher vesrion of Solaris 2.6/2.7(32bit) because that is documented to work.
