Dividing Catalogs
At some point you may wish to divide the contents of one catalog into smaller catalogs. Reasons for doing so include:
The catalog has grown close to its maximum size (e.g. 1 terabyte).
Your computer can no longer accommodate the number of records in the catalog effectively (processor or RAM limitations).
The contents of the catalog have become too diverse to be usefully categorized in one catalog.
Like many operations in Cumulus, there is more than one way to divide a catalog. The first way is best suited to smaller numbers of records.
To divide a catalog using drag and drop:
 
1. Make sure the catalog from which you wish to divide is the active window in Cumulus.
2. Create or open the catalog you wish to move records into in a separate window. Arrange the catalog windows so that you can see both.
3. Search for the records you wish to move to the new catalog, using any of Cumulus’ search options.
4. Click on or near a thumbnail in the original catalog and select Edit > Select All to select the records. (At this point you could cut and paste the records between the catalogs as one way of moving them, which would save you the step of deleting the old records in the old catalog.)
5. Click on the thumbnail of any of the selected records and drag the set into the new catalog window. A window is displayed allowing you to select whether the copied records shall maintain their category assignments (categories not yet existing in the target catalog will be created), or whether all category assignments shall be ignored.
The records are copied with or without category assignments, according to your selection.
NOTE: Cumulus doesn’t consider copying records from one catalog to another as “cataloging assets.” Therefore, the Asset Handling Sets have no effect on this action.
6. You can optionally delete the records from the old catalog by first clicking on the old catalog’s window to activate it, and then selecting Edit > Delete before the selection of records has changed.
To divide a catalog containing a very large number of records, it may be easier to export the records from the old catalog and import them into the new catalog. (See “Importing and Exporting”.)
After the export/import process is over, you can delete the records from the old catalog, as described above.
NOTE: Only with the drag & drop method you can decide on the handling of category assignments, The copy & paste and the export & import methods always preserve the category assignments of the copied records.
