Transportable tablespaces and Oracle downgrading...

Transportable tablespaces and Oracle downgrading...

So let's say you have a 10gR2 database that you need to downgrade to
10gR1.  You have no choice, you have to downgrade.

The immediate solution that comes to mind:

- export the entire database
- shutdown the database.
- trash the 10gR2 software
- install 10gR1 software, and create an empty database.
- import a lot of schemas with a ton of data.

Or, second option:

- export the transportable tablespace metadata.
- shutdown the database.
- trash the 10gR2 software
- install the 10gR1 software and create an empty database.
- import the transportable tablespace metadata.

Has anyone actually executed the second option??  Is it doable??
