Please read the installation notes of WinCC: WinCC projects > WinCC V7.4 SP1 No migration is required for projects created with WinCC as of V7.4 SP1. You only have to convert the project data. To convert the project data select the menu command "Tools > Convert Project Data" in the WinCC Explorer. Best regards Michael
