Audit Data Migration

[kmuller]

We are getting ready to migrate a large amount of reports from 8v2 to
8v4.  I need to take 60 days of audit data along with the reports. 

Does anyone know of a way to migrate the audit data from 8v2 to 8v4?  Some process in
place I dont know about?   
                                           
This is not an option for us and the data has to come across.           

Any help is appreciated.                                               

The 8v2 version is the base 8v2, np patches.                           
The 8v4 version is 8v4 fp2.
