Intelligent delegation of codes for mapping between versions of a classification system includes a method for receiving data that is classified with a first code. The first code is defined by a first version of the classification system, and the first code is to be re-classified to a second code that is defined by a second version of the classification system. The method also includes searching a database of profiles for content that matches at least a portion of the data, sending the data to a converter system having one of the profiles that is associated with the content responsive to the searching, and receiving, from the converter system, a mapping of the first code to the second code. The method further includes updating a database of codes with results of the mapping.
