I perform an in place upgrade from SQL 2008 64 bit Enterprise Edition to SQL 2008 64bit R2 Enterprise Edition. The upgrade completed successfully.
But SSRS upgrade was incomplete upon closer inspection. There is a number of issues.
1. Encrpytion keys could not be restored.
2. Reporting website erred out on finding version 120 instead of 147.
3. Tables dbo.ServerUpgradeHistory and dbo.tReportDataSources are missing.
I had performed 2 prior upgrades and it went fine. Any ideas
