    If you use the wfgroupdisable command, make sure that you enable all system tasks again when you are done. 

  2. Stop all workflows that are not disconnected and let them finish execution.

  3. Ensure that all users shut down all connected Desktops.
    If you want to see which Desktops that are connected, you can use the following command:

    Code Block
    $ mzsh mzadmin/<password> pico -view

    Note
    titleNote!
    This command will also display other pico instances, such as Execution Contexts.

  4. Shut down all ECs.

    Code Block
     $ mzsh shutdown <ec name> 

If you are running services on SCs, and want to minimize downtime, leave the SCs running during the upgrade procedure.
