◦ Downgradingthecontrollersoftwareshouldbearareoccurrence.Whensoftwareis
downgraded,anyconfigurationsettingsforfeaturesthatdon'texistinearlierversionsare
discarded.Becausesomeconfigurationsarediscarded,thecontrollermayrequiremanual
interventiontoensureeverysettingiscorrect.Restoringabackupfilethatwasmadewith
theearlierversionofsoftwareisrecommendedinstead.

◦ Ifadowngradefromversion4.00softwarebecomesanecessity,youcanavoidthese
problemsbydeletingallinvertersystems,distributionsystems,andallcustomdatabefore
