This maybe an easy question to answer, however I'm not certain on the easiest way to upgrade our existing Zenworks 10.3 Managed devices to Zenworks 11. I tried the deployment method, but since they are already managed and have a client on them the deployment fails.

Can anyone give me the easiest way to push the new ZCM 11 client to managed devices?

Most of our machines have .net 3.5 and windows installer 4.5.

Thank you.
