               Deep Discovery Analyzer has a rollback function to undo an update and revert the
                  product to its pre-update state. Use this function if you encounter problems with
                  the product after a particular hotfix / patch is applied.
               
               
               
                  
                     
                          | 
                        
                           Note
                           
                              
                              The rollback process automatically restarts Deep Discovery Analyzer, so
                                 make sure that all tasks on the management console have been completed before
                                 rollback.
