Customer would like to use config command to modify IL datasource from command line, to perform IL export -> IL import -> update datasource password in a batch.
Preferably the ability to do the same as InformationModelService OOTB.
We implemented the update-datasource command in 14.0, which enables you to change the connection URL, the username / password, and edit the 'User authentication' settings for your data sources. You can find more details in our documentation.
