Upgrading an application template

Niagara 4.9 (and later), supports application template upgrade. This procedure describes how to upgrade an application template.
Prerequisites:

When a station is running an application template and the Workbench user home applicationTemplates directory contains a newer version of the same template (as indicated by a higher version number assigned when it was last saved), the station > Config > Templates sub-menu will include the Upgrade Application Template menu option.


Perform the following steps:
  1. In the Nav Tree, click station > Config > Templates > Upgrade Application Template.

    This launches the Upgrade Application Template wizard, a simplified version of the application template install wizard, that includes an optional station backup step, and confirmation step.Image
  2. Click Next, and click Finish to complete the upgrade installation.Image
     
    CAUTION: The application template configuration will be preserved by the upgrade, but ad hoc edits made outside of the template configuration may be lost during the upgrade.
     

An upgrade progress report detailing the results of the upgrade displays in the window.Image

 
NOTE: Alternatively, upgrading application templates can also be accomplished through provisioning. For more details, see the latest version of the Niagara Provisioning Guide.
 
 
NOTE: If a component of a template is accidentally deleted, upgrading the template to a new version will restore the deleted component unless that component is marked as optional for the new template version.
