I have to upgrade Oracle 10.2.0.4 to 126.96.36.199 on a test system Windows 2003. Database is not that complex. I never upgraded oracle previously but other than that I have very good oracle knowledge and working experience. Challenge at the moment is that I am tied up with lot of other works plus I have to do it urgently without having time to look on internet.
Please give me simple steps e.g. in Oracle 11g installation folder open setup.exe etc etc.
