I have two databases, one is running oracle server 9.2.0 and the other one 8.1.7. I need to clone one database from 8.1.7 to 9.0.2. The size of database to be cloned is very large ( around 10 GB) therefore exp/import doesn't seems to be feasible here.

Can anyone of you. pls. let me know how should I proceed.

Thanks
