I am trying to export data from zendesk and import into service desk. I have exported a tickets.json from zendesk. How do i go about importing that into service desk, I see an option to import a json file in service desk, but just wanted to understand how does that work, when i start the import, am i going to be given an option to import into any particular service desk project and map fields etc.,? just wanted to make sure i do not accidentally import that into any other project.
