Migration of large data from on-line content management to archival content management

A method for content management in a file system includes creating a file system storage device with a storage area symbolic name. A core table data structure is generated including a core table partition field. An ancillary table data structure is generated including an ancillary table partition field. Partitioning rules for the file system storage device are cached based on the storage area symbolic name. Property values for a document are compared with the cached partitioning rules to determine a match for the storage area symbolic name. The document is stored into a partition of the file system storage device based on the storage area symbolic name. Metadata for the document is stored into a partition of the core table based on the core table partition field. Ancillary objects for the document are stored into a partition of the ancillary table based on the ancillary partition fields.
