    • The following product is going to be upgraded:

      Open Enterprise Server 23.4 23.4-150400.796.6 -> 24.4-0

      It’s safe to ignore the following messages as well. They have no impact on the channel upgrade.

      The following product is going to be REMOVED:

      "Open_Enterprise_Server Migration Product"

      REMARK: You can choose to ignore this message. The actual product that is being removed is OES 24.4 Migration Product.

    • During channel upgrade using zypper, some of the packages are going to be downgraded.

      NOTE:The packages may vary based on the setup.

  12. Once the upgrade is successfully completed, register the new products once again using the suse_register -L /root/.suse_register.log command.

  13. Reboot the server.

  14. IMPORTANT: After the reboot, log on to the server and run the following command to complete the OES services reconfiguration:

    yast2 channel-upgrade-oes
