I tried to upgrade a failover cluster running SQL Server 2008R2 to SQL Server 2012 but the upgrade wizard reported a rule failure:
"The SQL Server and Analysis Services features of the selected clustered SQL Server 2005 instance have been installed into separate groups. SQL Server 2012 setup can only upgrade clustered instances installed in a single group. To continue, uninstall either SQL Server or Analysis Services before you upgrade."
Apart from the fact that the current cluster is running SQL Server 2008R2 (it wasn't even upgraded from 2005) both SQL Server and Analysis Services are in the same cluster resource group. The advice to uninstall one or the other is also unhelpful because adding/removing features on a failover cluster is not supported (see http://support.microsoft.com/kb/2547273).
Any suggestions would be appreciated.
Thanks
