    Oracle's exp/imp utilities are not downward compatible.

    you must use 9.02.1 exp to extract from instance 9.02.03 and then you are able to imp into 9.02.1

    As mentioned, exp/imp is not backward compatible but it is forward compatible.

    That means you can export from 9.2.0.8 and use the imp of Oracle10g, that is not a problem, we always do that ...

    But from 9.2.0.3 to 9.2.0.1, what has been suggested is to use the exp program that comes with 9.2.0.1 and exp from the 9.2.0.3 database and then you should be able to imp to 9.2.0.1

    Basically, export should be done with the lower database version EXP utility (lower when you compare a source and a target database versions). Do the import using the target database version.
