If you are doing it once, I think export/import is the easiest way. The import will create all of the schema objects needed, if they are not already created. If you are going to be transporting data back and forth between instances on a regular basis, your best bet may be to set up a database link between the two, and run ‘insert into tablea select columns from tableb’. As long as both servers are defined in DNS, that should not be a problem. SQLNET 8i is compatible with ORACLE9I and vice-versa.

As for supported datatypes, check the Oracle documentation. 9i may intorduce some new datatypes not used 8i, but I can’t be sure.
