Hi Tim,
thanks for the advice. Network bandwidth is likely to cause some difficulty but currently if i can get it working i'd be happy.

Regarding performing the export on the 10G server, presumably you mean using the 9i version of exp (i've found a few forums on the Web where people say you must use the exp from the earlier version when going backwards, e.g. from 10g to 9i)?

If so, can you give me any pointers on the steps required to get the 9i exp command working on the 10g server?

I tried just copying over the 9i bin and lib directories and setting the LD_LIBRARY_PATH variable to point to the copied lib directory (because i got a 'shared library libclntsh.so.9.0 not found' error when running the exp command originally.

I realise the above is probably missing several steps or is naive in its approach, so could you tell me if there's additional directories i need to copy over or generally if its possible to port 9i's exp over to the 10g server without having to install an entire 9i instance?

Many thanks for your help so far,
Maurice
