Important Information

Updating your ClearSCADA License

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.

To determine your ClearSCADA version, please refer to the steps within Determine Your ClearSCADA or Geo SCADA Version.
