## Overview
Execute the merge command of CodeDefiner below to copy the old resource **C:\web\pleasanter_bk\Implem.Pleasanter\App_Data\Parameters** to the new resource **C:\web\pleasanter\Implem.Pleasanter\App_Data\Parameters**.
Then, apply the parameters that were added and deleted from the old resource version to the new resource version based on the patch file in ParametersPatch.zip.
