Is it any way to downgrade from 11.2.0.4 to 9.2.0.8?

Upgrade: 9.2.0.8 -> 11.2.0.4 => OK  (* when using upgrade script)

Downgrade: 11.2.0.4 -> 9.2.0.8 => Fail   (* when using downgrade script)

From Doc ID 443890.1, downgrade to 9i or lower is only possible using export/import.

It's mean that downgrades from Oracle Database 11g Release 2 to Oracle Database 9i are not supported.

is it any way to downgrade from 11.2.0.4 to 9.2.0.8 except export/import?

Howdy, Stranger!
