ERP 8 to ERP 9

Hello Forum,
Just wanted to know whether reports/application developed using OneWorld B7334 SP 21 will work on ERP 9.What changes need to be done?Has anyone come across such kinda situation?
Thankx

The database schema has changed for ERP9 somewhat. There's a document on the KG detailing the changes table-by-table. When we did the upgrade we spent a long time testing custom objects and re-designing when appropriate.

Chris, do you still know where this document is, or do you still have a copy? I cannot find the schema changes anywhere!!! I have been looking for hours.

Sorry, I don't have a copy available but as I recall it's called 'Database Changes for Table Conversions Verification = Release ERP 9.0'. It a large pdf document, over 700 pages.
