Upgrade a ClearSCADA Server in a Lone Server Architecture

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.

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.

To upgrade your lone ClearSCADA server:

1. First, undertake the appropriate preparation (see Preparing to Upgrade ClearSCADA).

   With correct preparation, you will:

   • Find out about any version-specific details relating to your current version and the new version of ClearSCADA.
   • Make a backup which can be used to restore your system should an unexpected issue occur.
   • Obtain the required upgrade files so that the upgrade can be completed as efficiently as possible.
     
2. Shut down the ClearSCADA server. (The installation process requires the server to be shut down.) For information on shutting down a server, see 'Stop the ClearSCADA Server' in the ClearSCADA Guide to Server Administration.
3. Install the ClearSCADA update on the ClearSCADA server. To do this, run the Setup.exe file which is part of the ClearSCADA update. When you run Setup.exe, the installer will run and install the correct files for the server’s operating system (64 bit or 32 bit).

   Some publishers may re-package ClearSCADA to be part of another package. With these packages, you can use the installer for the package to install updates for ClearSCADA and the other product together.

4. Install updates for any extensions. (Skip to step 5 if your system does not use extensions).

   To install an extension, run the installer application supplied with the extension upgrade.

   If you do not update all of the extensions, ClearSCADA may not run correctly.
   

5. Install updates for any DDK drivers. (Skip to step 6 if your system does not use DDK drivers).

   The ClearSCADA update includes the latest version of drivers created by Schneider Electric. However, if your system has DDK drivers created by a Third Party organization, you will need to install the appropriate updates. This is because DDK drivers are associated with a specific version of ClearSCADA—when you upgrade ClearSCADA, the DDK drivers need to match the new ClearSCADA version.

   If you do not update all of the DDK drivers, ClearSCADA may not run correctly.
   

6. Install updates for any Third Party applications that are associated with a specific version of ClearSCADA. (Skip to step 7 if your system does not use any Third Party applications with ClearSCADA).

   For information on any Third Party applications that you use with ClearSCADA, please contact the publisher of the application.
   

7. Restart the ClearSCADA server.

   For information on restarting a server, see Start and Stop the System Server.

8. If your ClearSCADA server is connected to clients that run an older version of ClearSCADA, you should enable server emulation. This will allow the clients to continue to function as expected while they are awaiting upgrade. Any new features in the ClearSCADA upgrade will be unavailable on the clients until the clients have been upgraded.

   For information on enabling server emulation, see Server Emulation.

9. Upgrade your ClearSCADA license (see Upgrading a License).
10. Upgrade your ClearSCADA clients:
    • Upgrade Your ClearSCADA Clients (WebX Excluded)
    • Upgrade Your ClearSCADA WebX Clients.
11. If you previously enabled Server Emulation, log on to the Server Configuration Tool and clear the Present a different server version to clients check box (System Configuration>Emulate Server Version). This disables the server emulation feature.

You have now upgraded your ClearSCADA server and clients.
