Once the release came out I had the change to run the patch installer on my homelab to upgrade it and you can do the same. The following steps are required during the upgrade –

  • Download the PATCH installer from the link above or the ISO file – either will work to upgrade but the patch installer is what I used.
  • Extract the ZIP file and run the EXE file by double-clicking on it.
  • The upgrade installer starts and is displayed on screen.
  • Click on Next to proceed to the next screen which is the License Agreement.
  • Click “I accept” and then the system will run a Configuration Check to ensure the upgrade is able to proceed.
  • Once the check completes the Ready to Install screen comes up – here you will check off the “Update remote components automatically” or leave it unchecked so when you open the console you will then be prompted to run the updates to Proxies, Repos, etc. I would recommend the automatic update checkbox be selected.
  • Once ready click the Install button and allow Veeam to update your server to Once complete you can click Finish to exit the upgrade wizard.

That completes the upgrade process and you can now launch the Veeam Console to check your jobs and settings to ensure nothing is in error or did not update and is pending from the upgrade installation.
