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

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.
