XI Upgrade on 6.40 system to the 170 kernel

[Former Member]

Hi all hope someone can help. I need to know what MUST BE upgrade when switching to the 170 Kernel. Whether we need to install database patch, or jdk or crm patch etc etc.

I am on a JDK 1.4 as 6.40 release

Hi John,

the Kernel is downwards compatible.

It is more of a concern when you upgrade your system and forget to upgrade the kernel.

But it is advisable that you update everything at once.

Thanks But i guess my question is when you move to the 170 on the XI 3.0 system on the 640 kernel. Must the other components be increased and if so what ones for example the JDK

The kernel can live with components which have a lower patch lever. It is the other way around which is difficult. For example SAP_BASIS patchlevel 19 does require a higher kernel patch than SAP_BASIS patch level 16. So you can patch the kernel and leave all other components on their respective patch level, but the question is why would you patch the kernel and don't want to patch the rest.

Hope that helped
