TuxCare documents a procedure for replacing Ksplice with KernelCare on a supported kernel. This is a server administration task: check kernel compatibility and licensing before changing its patching system.
The official script uninstalls Ksplice and then installs KernelCare. Read the vendor prerequisites and arrange a backup and an appropriate maintenance window. The procedure can stop if the Ksplice components cannot be removed; do not assume every migration will complete without interruption.
First, download and run this script:
$ wget https://patches.kernelcare.com/ksplice2kcare
Run the command:
$ bash ksplice2kcare _YOUR_KERNELCARE_KEY_
If you are using IP licenses, run:
$ bash ksplice2kcare IP
The script checks two letters "IP" and assumes an IP license in this case.
The full log file can be found at
/var/log/ksplice2kcare.log
