At the moment. It is is possible to install/update data source connectors to the newest version. While in some cases, the new version of the connector is not compatible with the installed version of TimeXtender.
This means you have to install a older version of a data source connector, or you need to update TimeXtender Data Integration to the newest version.
It would be way easier if only the data source connectors were shown in the portal that are compatible with in installed TimeXtender Data Integration version. Or at least, a pop up/warning is visible that is showing the compatible versions for the selected connector.
