Hi Jagan,
First of all many customer make the mistake of brining in the wrong kernel in to the upgrade by selecting the wrong kernel binaries during stackXML generation. You can prevent this error in the first case by selecting the
correct kernel while generating the stackXML.
Now how to know your correct kernel during the upgrade is by chcking the correct version of the target you intent to upgrade in service.sap.com/PAM -> specify the release or release + EHP level you are upgrading to . Once the release information page opens , click on the tab Technical release information -> choose Database platform
Choose on the correct OS and DB version you are in and PAM will outline the comptiable kernel you have to use . So you will know the correct kernel to use. Accordingly pick the TP and R3trans tools in market place and update your system. It is best to update the kernel than individually updating the TP and R3trans tools.
The above method of finding the kernle is the best method. This is not assumption based and will work perfectly. The SCOPE section shows te correct kernel you need to use . In case you have doubt to use use normal or EXT kernel for your release , I would recommed you to read the notes that are provided in the ADDITIONAL INFOTRMATION tab by clicking on the DISPLAY button.

Varun.
