When you open a report that was created in a previous
version of Report Studio, it is automatically upgraded. Any problems
detected during the upgrade process appear as information messages 
and error messages 
in the Upgrade Information dialog
box. You must fix any errors in the report and then validate the
report before you can run it. In some cases, the information or
error message is linked to the location of the issue in your report.
To go to the location of the issue, click the message, and then
click Select. If only warnings and information
appear in the dialog box, these will disappear when you click OK.
Tip: To view this dialog box again, from the File menu, click Upgrade Information.
Once a report is upgraded to the most recent version of IBM Cognos 8, you can no longer open it with a previous version of IBM Cognos 8.
For more information about changes in the product behavior, see Upgrading to IBM Cognos 8 BI 8.3: Changes in Product Behavior on the IBM Cognos Resource Center (http://www.ibm.com/software/data/support/cognos_crc.html).
