Among Niagara provisioning job steps, the Upgrade Out-of-date Software step (UpgradeOutOfDateStep) compares the versions of software installed on the station’s host with the latest versions of the same software in the Supervisor’s software database. Any software found with a higher version on the Supervisor is then installed to the station. Find it in the New Job Step menu when adding a step in either the Niagara Network Job Builder or Niagara Network Prototype View.

Although not typical, please note that the latest version of any software module found under the Supervisor’s software database (under !sw) is always installed by this step, even if the Supervisor itself is using an earlier installed version (as found in its !modules directory). Normally, the Supervisor has the latest versions of software modules installed, so this distinction is moot.

When the job executes, upgrade out-of-date-software steps are combined with other software install steps and copy file steps, to run more efficiently.
