If multiple generations of a cube have been created, special considerations
are needed when archiving or deleting these generations. It is possible to
archive an old cube generation into another schema or under another name.
The cube will then be available for access to historical data. If you are
deleting cube generations, it is important to note that a cube that is an
earlier generation must be deleted with PROC OLAP. Deleting only the metadata
will not work for generations of cubes.
Because cube generations generally look through to aggregation data
in previous generations, cube data cannot be physically deleted as long as
another generation is dependent upon it. Only those physical files that are
not needed by the new cube (for example, member and property trees) are actually
deleted. The aggregation files remain available to subsequent generations.
In addition, the metadata registration in the metadata repository is deleted.
