Upgrading Your System

To upgrade your system to Unbreakable Enterprise Kernel Release 6:

Enable access to the appropriate ULN channels or yum repositories as described in Subscribing to ULN Channels and Enabling Access to Oracle Linux Yum Server Repositories. It is good practice to disable any other UEK channels or repositories that you may have configured previously.
After enabling access to the appropriate channels, run the following command to upgrade the system to UEK R6 on Oracle Linux 7:
```
sudo yum update
```
Alternatively, run the following command on Oracle Linux 8:
```
sudo dnf update
```
After upgrading the system, reboot it, selecting the UEK R6 kernel (version 5.4) if this is not the default boot kernel.
