How to update an Insight object using CSV Import?

[Martyn]

Im trying to update objects using the Insight CSV Import tool like i used to on the Mindville version.

When i try to update an object i get this error

Error occured during import.

Import took 6 second(s).

Error messages:

Error(s) for object type: MyObject

• 1008000001(null): context: rlabs-insight-attribute-29; messages: [ErrorMessage{i18nKey='rlabs.insight.i18n.constraint.violation.unique', parameters=[Telemetry ID], additionalMessage=null}];

I understand it is telling my that the object already exists, does this mean we cannot use this tool to update?

Thanks
