Once a State received electronic certification, the MDF was no longer prepared for
                  EDCS cases transferred to the DDS (except for exclusions). Adjudicative documentation
                  is stored only in CEFs, and CEFs, are the official agency records for electronic cases.
                  (See DI
                     
                     81010.030 for cases that are CEF exclusions, EDCS Exclusions and Limitations.)
               
               After certification, CEF procedures apply to EDCS cases transferred from FOs to the
                  DDS on or after the certification date.
