[Issue Type] Dimension and hierarchy renaming by migration may cause different query results [Issue Description] 
Dimension hierarchies in SQL Server 2000 Analysis Services are internally represented as separate dimensions, and a naming convention is used to identify them. Migration to Microsoft SQL Server 2008 might create a separate dimension, with a new name, for each dimension hierarchy instead of combining the dimension hierarchies together under the parent dimension because auto-exist results in different security rules than would apply in earlier versions of Analysis Services.
