We successfully upgraded one of our development servers to SQL Server 2012 SP2.
We are now performing cleanup and found that there are some files in the SQL 2008 R2 folder MSAS10_50.MSSQLSERVER that is being used by the SQL Server 2012 Analysis Services.
One such file is the configuration file, msmdsrv.ini. I tried to move the file by stopping the service, copy the folder to MSAS11.MSSQLSERVER, changed the service entry in the registry (CurrentControlSet\services\MSSQLServerOLAPService) and restart the service. The service failed to start, and there was no meaningful message in the log.
What is the correct way to "cleanup" the SQL 2008 R2 Analysis Services so that the configuration files are in the SQL Server 2012 Analysis Services folder?
