    Hello,

    Just some observations.

    1) You can rename the current “exe” folder to something like “exe_old” and then create a new, empty “exe” folder where you will uncompress the new kernel;

    2) The kernel 720 is not supported anymore. Consider using the kernel 721 or 722;

    3) The following SAP notes have complete / detailed steps to perform the kernel upgrade. There are (several) steps missing at this document.

    • 1716826 – Usage of the downward compatible kernel 721 (EXT)
    • 1713986 – Installation of kernel 721 (EXT)
    • 2133909 – Usage of kernel 722 (EXT)
    • 2115344 – Installation of Kernel 722 (EXT)

    Regards,

    Isaías
