Hello
But while upgrading the kernel the kernel the sapcpe.exe is showing red.
So that means sapcpe was unable to copy the files from the DIR_CT_RUN to the DIR_EXECUTABLE location.
Have you checked the sapcpe.log file ?
Are you doing the kernel upgrade manually before starting the upgrade ?
If you are doing a kernel upgrade then delete all the old kernel files before putting the new files.
