OK, yes, you could use the expdp utility to launch it from a different oracle home, but it's just a wrapper to make the appropriate calls to DBMS_DATAPUMP.
I'm not sure if doing so would automatically set the coorect 'VERSION' parameters for you.
I really don't see why you would want to do such a thing though.
CarlYou have a good point indeed, Oracle is not setting the correct version...
Assuming it is for further import into a 10.2 database from a 11.2 database :
