Its a bit of a hack but it works.
Go to SQL Server and look at the DBSchemaVersion tables in the PPSPlanningService DB and the PPSPlanningSystem DB. They should have entries like this:
Change UpgradeStatus to NULL in both DB’s.
For Planning follow the steps in technet. http://technet.microsoft.com/en-us/library/cc514369(TechNet.10).aspx
For Step 3, Run the <sp1filename>.msp from a command and use the switch SKIPREQCHECK=1. You only need to run the switch for the PPLSrv.msp and PSCSrv.msp files.
For Montoring Server, you do not need to run the configuration manager. I would however delete the Apps directory under Documents and Settings/<user>/Local Settings, which is where Dashboard Designer lives, and go back to Monitoring Central and Download Dashboard Designer again.
