Hi experts,
I have a SAP Netweaver MDM 5.5 and I'm going to upgrade de kernel from 7.0 to 7.21. I'd never changed the kernel in this system before and when I've realized that it has two instances and so, two /sapmnt/<SID>. My question is: How do I upgrade/change the kernel? Do I only change the new 7.21 kernel in both /sapmnt/<SID>/exe or is it necessary to perform additionals tasks?
Regards.
Hello Luis,
Are you completed your kernel upgrade in MDM?
I am also struck in nearly same situation. Is MDM kernel upgrade different from normal SAP kernel upgrade. Please suggest.
Thanks in Advance
Chandra

Hello
First read these SAP notes.
1713986 - Installation of kernel 721 (EXT)
1728283 - SAP Kernel 721: General Information
1744209 - SAP Kernel 720 and 721: Versions and Kernel Patch Levels
1716826 - Usage of the downward compatible kernel 721 (EXT)
You need to remove all the files related to the old kernel and then put the the 721 release kernel files in the DIR_CT_RUN location (/sapmnt/SID/exe.
Trigger sapcpe to replicate the kernel files to the local executable location (usr/sap/SID/DVEBMGS00/exe)

Hi Luis
If you are having schedule to upgrade the both instance, you can follow the SAP Note as mentioned by Benjamin. and you have to copy the Kernel file to "\\sysdec01\SAPMNT\SID\SYS\exe\UN\NTADM64 for windows " (Not on /sapmnt /MAB/exe & /sapmng/MCD/exe ) you can follow the kernel upgrade steps from the SCN link
