SAP PI Server kernel

[Former Member]

Dear Experts,

Would like to check whether there are any dependencies on support packages level if we are to upgrade our SAP Kernel from version 7.11 to 7.20 ? Is there a minimum support package level which the server needs to have before upgrading the kernel to 7.20 ? (kernel <7.20 will be out of support soon)

Anything to take note when upgrading the kernel from 7.11 to 7.20 Ext UC ?

Appreciate any expert comments, thank you in advance.

Hi,

>>>>7.11 to 7.20 ?

there is no PI 7.20 version of PI - so please don't do that

you should only upgrade accordingly to the SAP prepared paths:

from 7.11 to 7.3 or to 7.31 directly

Hi Michal,

I am not upgrading the PI to another version, just the kernel (from 711 to 720), would like to know whether any dependencies which i need to check before doing so

Appciate very much if anyone could share their knowledge on this. Thanks.

Hi,

You can just upgrade your kernel 7.11 to 720, it is downward-compatible. All our PI 7.11 systems are running on 720 kernel now.

as usual, backup your kernel before upgrade.

hi,

sorry - I didn't read the Q correctly

Nicholas is 100% right of course - our 7.11 is also on 7.20 kernel as per screenshot
