Firmware/Library 
                Upgrades
               Configuration 
                files are usable with different firmware and library revisions, 
                i.e. older configuration files will generally work with newer 
                versions of the firmware and library. The exception is when a 
                field from an older configuration file is no longer supported. 
                In such a case, one of the following messages will be displayed:
                
                
               `field`: 
                name not found
              
                This message indicates that the `field` 
                member of an MPI Config{} structure is either no longer supported 
                or in error.
              
                `field`: `value`: 
                name not found
               
                This message indicates that the `field` member of an MPI Config{} 
                structure is a pointer and the symbolic XMP address `value` is 
                either no longer supported or in error.
              
                In either case the field will be ignored.
              
                If a new field has been added, there 
                is no way for an older configuration file to handle it. Newly 
                added fields will remain at their current value.
              
                To upgrade to a new version of the 
                MPI library and/or XMP firmware while retaining custom configuration, 
                do the following:
              
                -  config 
                  -flash get all.cfg
 
                -  install 
                  new library and firmware
 
                -  config 
                  -flash set all.cfg
