Oracle Version Upgrade Guide (9 → 10)

Oracle verison upgrade instructions (8 -> 9)

Running these commands could break your system, remember to create backups!

Connect to your server

Establish the connection using either Remote Desktop or an SSH connection. If this is your first time connecting, please refer to this guide.

Start by updating your packages:

sudo dnf update -y

Reboot:

sudo reboot

Install leapp:

sudo dnf install -y leapp-upgrade

Run the preupgrade check:

sudo leapp preupgrade --oraclelinux --enablerepo /etc/yum.repos.d/leapp-upgrade-repos-ol10.repo

Report has 2 "Inhibitoris", Let's fix that.

In this case, the inhibitor is "Legacy network configuration found".

Fix it as follows:

Create a new connection:

sudo nmcli connection add type ethernet con-name dhcp-eth0 ifname eth0 ipv4.method auto ipv6.method auto autoconnect yes

Activate the newly created connection:

sudo nmcli connection up dhcp-eth0

Remove the old connection:

sudo rm -f /etc/sysconfig/network-scripts/ifcfg-eth0

Run the pre-upgrade check again:

sudo leapp preupgrade --oraclelinux

When you no longer see any Errors or Inhibitors, start the upgrade:

Start the upgrade:

sudo leapp upgrade --oraclelinux --enablerepo /etc/yum.repos.d/leapp-upgrade-repos-ol10.repo

(The upgrade may take some time, so please be patient.)

If the above command results in an error, try another repository:

sudo leapp upgrade --oraclelinux --enablerepo ol10_codeready_builder

When the "upgrade" completes without issues, reboot:

sudo reboot

Select: "OL-Upgrade-Initramfs"

Oracle should now be upgraded

Check the version:

cat /etc/os-release

Upgrade successful!
