When you have the appropriate update files for ClearSCADA and any extensions, DDK drivers, and Third Party applications, you can upgrade your ClearSCADA system. For more information on obtaining these update files, see Preparing to Upgrade ClearSCADA.
ATTENTION: Read the ClearSCADA release notes for your version of ClearSCADA before starting the update process. The release notes may contain important details about installing updates for your specific version of ClearSCADA.
In this section, we explain how to upgrade your ClearSCADA servers using separate installers for:
- ClearSCADA
- Extensions
- DDK drivers
- Third Party applications (that target ClearSCADA).
Some publishers may repackage ClearSCADA updates so that you can install all (or some) of the components (above) from a single installer.
Irrespective of the type of installer(s) you have, you will need to install updates for ClearSCADA, extensions (if used), DDK drivers (if used) and Third Party applications (if used) on the Standby servers first. You will then need to install the same components on the Main server.
