I have successfully completed upgrade to 8.00 version and am able to access with out any issues.
But during the end of upgrade I have recivedan message which says as below:
The following database objects are invalid. This is likely the result of data model changes made during the upgrade. Please reconcile these items before you start the PPM Server, particularly if they are core PPM Center objects.
It seems that most of these views are pulling data from Benefits and Budgets. The whole table structure for these changed in 8.0, so the code behind the views need to be updated to reference the Financial Summaries instead of the individual Budget and Benefit. The Data Model Guide document will give you the layout of the new tables that you will need to use.
