question: private boolean vdcPropertiesChanged ( ) { long localVdcConfigVersion = localVdcPropInfo . getProperty ( VdcConfigUtil . VDC_CONFIG_VERSION ) == null ? 0 : Long . parseLong ( localVdcPropInfo . getProperty ( VdcConfigUtil . VDC_CONFIG_VERSION ) ) ; long targetVdcConfigVersion = targetSiteInfo . getVdcConfigVersion ( ) ; log . info ( "local vdc config version: {}, target vdc config version: {}" , localVdcConfigVersion , targetVdcConfigVersion ) ; return localVdcConfigVersion != targetVdcConfigVersion ; }
target:  Check if VDC configuration is different in the database vs. what is stored locally
