Downwards Compatible Kernel (DCK)

Downwards Compatible Kernel (DCK)

Within a kernel code line kernel release can be download compatible. In a given #sap #netweaver / #s4hana install you can upgrade the kernel to newer DCK.

Example : Kernel 777 supports not only its native SAP S4 HANA 1909 version but you can also use kernel 777 in SAP S4 HANA 1809 installation instead of kernel 773.

When a kernel release goes out of maintenance , it is usually replaced by DCK. The newer kernel offers new features and supports newer os and db. Thus it is recommended to upgrade to newer DCK Kernel as long as it supports NW/ SAP S4 HANA and os/db combination
