Post Upgrade Actions

1. Reboot the System: Execute the command below.

   sudo reboot

2. Verification and Validation: After the system is rebooted, confirm the upgrade to Ubuntu 24.04 by executing the command below.

   lsb_release -a

   
3. If /etc/resolv.conf is a symlink to a different file, follow these steps:
   1. Remove the existing symlink:

      sudo unlink /etc/resolv.conf

   2. Create a new file /etc/resolv.conf with the backed-up configuration.
   3. Verify the updated contents.
4. Enable and start the auditd.service again.

   
   sudo systemctl enable auditd.service
   sudo systemctl start auditd.service
   sudo systemctl daemon-reload

   Post executing, ensure that the auditd.service is active and running
5. Validation for On-Premise: After completing the upgrade for all nodes, log in to the CLI and verify that all pods in the cluster are running using the command below.

   kubectl get pods -A

   If all components are operational, access the application via the GUI to confirm a successful login.
6. Validation for Cloud Connectors (CC): Once the OS upgrade is complete, verify that the application is accessible through the GUI.

The system should now be successfully upgraded to Ubuntu 24.04.
