Unable to upgrade SQL Server 2008 R2 to SQL Server 2012 SP1


  • I'm encountering error after error, after successfully installing the upgrade advisor (which took some doing) and running it with essentially no warnings/errors (the one warning was on the connection strings, as I recall -- and all of the warnings had a "fix after" status.

    First failure involved SSRS and the inability to create the "managed account". Backed out the upgrade using

    Now the failure involves SSAS and unable to connect to analysis services with name MSSQLServerOLAPService.  That is the logical name for the service, although it shows up as just MSSQLServer when looking at it in the services list.  I tried setting the service account to a local account as  well as to Local System -- did not make a difference, the upgrade couldn't apparently find it regardless.

    Has anybody successfully done an in place upgrade from SQL Server 2008 R2 to SQL Server 2012?

  • Apparently, my last effort was successful.  To get to this point I had to:

    Change SSRS from integrated mode to native mode

    De-install SSAS.
