Upgrade Connector
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 2025.R1.0 is compatible with connector versions 4.105.3. 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.
Download the Plant Integrations installation file
<trendminer-hc-X.Y.Z.zip>from the TrendMiner download site.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
During this upgrade all web.config settings will be migrated into a database and will no longer be read from the web.config file after the upgrade.
Important to know:
It is extra important to take a backup of the web.config file before starting the upgrade for disaster recovery purposes. In case a downgrade of the connector would be required the backup of the web.config file needs to be restored manually.
After the upgrade all changes in the connector configuration can be done from within ConfigHub -> Data sources. All configuration options are documented on the specific provider documentation, accessible from the connectivity overview page.
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 ErrororFailed Error on remote service - HttpCode: '500'orAccess deniedTo reset the permissions you can follow the instructions listed in the connector installation guide.
Stop the Plant Integrations application pool in ‘Application Pools’ to begin the upgrade steps.
Right-click on the website and choose ‘Deploy’ - ‘Import Application’.
Select the TrendMiner Plant Integrations zip archive and click ‘Next’.
Click ‘Next’.
Remove the Application Path to a blank field (default will show HC) and click ‘Next’.
Click ‘OK’ to continue. If this warning message does not appear, go back to the previous step.
Click ‘Next’.
Click ‘Finish’ to complete the Plant Integrations deployment.
Start the Application Pool again.
