Upgrade Connector

Important notes

  • Before upgrading a connector, please make sure all TrendMiner appliances which connect to the connector are upgraded first as the TrendMiner appliance is backwards compatible but forward compatibility cannot be ensured (a newer appliance can connect with an older connector but not necessarily the other way around).

  • TrendMiner version 2026.R3 is compatible with connector versions 5.4.x. For the duration of the upgrade it is possible to connect to an older connector version but to ensure new features are successfully deployed connectors should be upgraded with every TrendMiner upgrade.

  • In case you need to perform multiple connector upgrades at once we strongly advise to skip at most 1 version. For example, to upgrade from version X-4 to version X, please upgrade from X-4 to X-2 and from X-2 to X.

    There are no technical restrictions on how many versions can be skipped during an upgrade but in case too many versions are skipped important migrations might be skipped which can lead to issues.

Upgrade Self-Hosted connector

  1. Download the correct Plant Integrations installation file <PlantIntegrationsSetup-x..-X.Y.Z.msi> from the TrendMiner download site. If in doubt which file you need, check the installation documentation for more information.

  2. Run the installer and install the new version over the existing one. The old version will automatically be replaced.

Upgrade Web-Hosted connector

  1. Download the Plant Integrations installation file <PlantIntegrationsWebDeploy-dist-X.Y.Z.zip> from the TrendMiner download site.

  2. Before starting the upgrade, make a copy of your Plant Integration folder as a backup. This folder is usually located at C:\inetpub\PlantIntegrations.

    Important

    When a connector backup needs to be restored, only copy the files within the main directory (e.g. "PlantIntegrations"). Never overwrite the directory itself. Overwriting the directory will clear all configured permissions on the directory which will prevent you from updating data sources or making changes to configuration from the TrendMiner application.

    In the ConfigHub UI this can be recognized by the data source errors 500 Internal Server Error or Failed Error on remote service - HttpCode: '500' or Access denied

    To reset the permissions you can follow the instructions listed in the connector installation guide.

  3. Stop the Plant Integrations application pool in ‘Application Pools’ to begin the upgrade steps.
