Prior to performing an upgrade of your ClearSCADA software, it is necessary to evaluate whether your current license is compatible with the new version of ClearSCADA.
License keys may need to be updated when upgrading to a new major or minor release. Provided that the server license you have supports a server version greater than, or equal to, the version of ClearSCADA to which you are upgrading, you do not need to update your license. If the ClearSCADA software version is greater than the license version, you will need to upgrade your existing license.
As a result of the changes to the ViewX User Interface for ClearSCADA, the strategy for upgrading to ClearSCADA 2014 R1 from previous versions has been modified. Adhering to the previous strategy of upgrading ViewX clients prior to the ClearSCADA server will result in these upgraded clients being unable to communicate with the system until the server is upgraded to ClearSCADA 2014 R1.
The recommended strategy for upgrading to ClearSCADA 2014 R1 is to upgrade the ClearSCADA server(s) first, followed by any remote clients. Previous versions of ViewX will provide remote clients with continued connectivity with ClearSCADA before and after the upgrade to ClearSCADA 2014 R1, after which time these clients can be upgraded to ClearSCADA 2014 R1.
It is recommended that all ViewX clients be upgraded to ClearSCADA 2014 R1 following successful upgrade of the server(s).
Server emulation is not required to support previous ViewX clients and should not be enabled on a ClearSCADA 2014 R1 Server.
Supported client versions include ClearSCADA 2010 R3, ClearSCADA 2013 R1 and ClearSCADA 2013 R2 (and corresponding Service Packs for each version).
ViewX clients prior to ClearSCADA 2010 R3 will not be able to connect to a ClearSCADA 2014 R1 server.
Removal of the Integrated PLC Driver
ClearSCADA software previously had an option of an integrated Kepware Technologies KEPServerEX4 PLC driver; however with the evolution of ClearSCADA this integrated PLC driver suite previously is no longer available within ClearSCADA 2014 R1 or future versions.
To ensure the continuous, long-term operation of your system we recommend that you migrate to an external installation of KepServerEX5 (Kepware's latest version) prior to the upgrade to ClearSCADA 2014 R1. This migration will require the conversion of any existing PLC database objects into corresponding OPC database objects, for which a documented procedure and software tool has been prepared and will be provided free of charge from Schneider Electric on request.
An upgrade to ClearSCADA 2014 R1 should be performed only after all PLC database objects have been migrated to corresponding OPC database objects.
ClearSCADA 2013 R2 Standalone Server
Perform migration of any PLC objects in the database to OPC objects, including stand-alone installation of a Kepware KepServerEX5 (or equivalent) OPC server.
