UEK 8 is the default kernel on Oracle Linux 10.

UEK 8 is made available for installation on Oracle Linux 9, starting with the Oracle Linux 9.5 release, and is the default kernel on Oracle Linux 9.6.

The suggested migration path for upgrading the system from an earlier UEK release to UEK 8 is as follows:

• If you're running an Oracle Linux 8 release you must upgrade to Oracle Linux 9 to install UEK 8. For instructions on upgrading an Oracle Linux 8 system to Oracle Linux 9, see Oracle Linux 9: Upgrading Systems With Leapp.

• If you're running an Oracle Linux 9 release, you must ensure that the system is updated to the latest update level before installing UEK 8.
