Hello,

Yes kernel files should be copied from the CT_RUN directory defined in the start profile.

Sapcpe programme should copy them.

See note

Hi,

In case CI & application instances share the same /sapmnt/<sid>/exe then only do the kernel upgrade in CI. After kernel upgrade when CI comes online then simply restart the application instance.

But if your /sapmnt/SID/exe is not shared between the CI & application instances then you have to do the upgrade separately.
