They have trail files and a live terminal. Which do we connect?

The customer can upload trails or point their terminal at us. What should support ask them to do first?

If they want live capture, they copy the workspace Snapshot Webhook URL and point OL Terminal at it. If they already have files, they upload .trail, .json, .trm, or native OpenLegacy XML. Preview does not save. Ask which journeys they want kept, then look at identified screens before anyone promises a Hub flow. A raw upload is not a finished operation.
