Data Conversion Validation - PS Financial 9.0 -> 9.2

We are upgrading from PeopleSoft Financial 9.0 and PeopleSoft Financial 9.2 and are using the delivered PeopleSoft upgrade tool to convert delivered records and data from 9.0 to 9.2.  For the customizations, we'll be writing our own data conversion validation routines. 

However, for the delivered conversion process, does Oracle provide any utility/tool/scripts that can be used to validate converted data (e.g., ledger balances or open item balances, etc.) between 9.0 and 9.2 environment?  If not, does Oracle provide a suggestion on what delivered reports can be used to validate data between 9.0 and 9.2 environment to ensure all critical data came over accurately and completely?  I am sure other shops that have upgraded from 9.0 to 9.2 would have gone through some similar validation process before and after running the delivered conversion process.
