backwards export

[Jeroen van Sluisdam]

Hi,   We are investigating possibilities for migration of an oracle 7.3.4 to oracle 9i. We want to separate our production DB from the app-logic such that we can migrate from oracle 7.3.4 on hp-ux 10.20 to oracle 9i on hp-ux 11. Problem is our development and test-environment because we cannot separate the logic at the same time here also from the db (costs). Does anyone have any experience with exporting from oracle 9i to oracle 7.3.4 ?   I found the underlying note on metalink about the same problem but with oracle 8. I have limited experience on oracle8 and none on oracle 9. So I hope you can give some tips. ........................... You need to run the 7.3 version of export against your 8.0 database via sqlnet/net8. Beforehand, you need to run rdbms/admin/catexp7.sql against your 8.0 database. This creates the 7.3 export views required. Note that if you have used any 8.0 specific features (e.g. objects) these will not be exported for obvious reasons. .........................   Tia,   Jeroen
