After installation, any eds file imported in Unity Pro catalog must be re-imported.
To avoid re-import, the following workaround can be used to keep DTM eds in the DTM catalog :
• Before Unity Pro or HotFix install : backup and save edslist.xml which is under \\ProgramData\Schneider Electric\Unity Pro Generic EtherNetIP DTM\Device Library
• After Unity Pro or HotFix install : install : Replace the new edslist.xml created after the installation by the backup of the edslist.xml.
