1. Do not use any 8.1.7 specific features after the upgrade.
2. Take a cold backup while at 8.1.7
3. Run the downgrade script from $O_H/rdbms/admin directory (d0800060.sql).
4. Backup
5. Rollback your changes to all other scripts/files ($O_H, listener file etc..etc..)

Best approach:
Create a test 8.0.6 database, upgrade it to 8.1.7, make and record a few changes to it. Downgrade it and make sure all the changes are still there. And you understand what you are doing.

To CYA even more:
Call Oracle Support/Log an iTAR and have them send you the exact steps for such a downgrade :)

Good luck.

Hello All,

We are in the process of upgrading a database from 8.0.6 to 8.1.7. The upgrade is not a problem. We have been asked to come out with a fast rollback strategy in case we have to fall back, say after a week, to the 8.0.6 database with no data loss. Any fresh ideas?

Thanks
Raj
