The information recorded in the snapshot reflects the state of the device at the time snapshot was captured. A snapshot only contains outputs of custom commands that are part of a snapshot template. (You must select a snapshot template when you capture a snapshot.) See Defining Custom Snapshot Templates and Editing Custom Snapshot Templates for information on using snapshot templates.

When upgrading to the 2018.2 train, only snapshot templates are migrated but not previous snapshots. CloudVision stores migrated templates without any device list associated with them. Hence, they are marked as unscheduled. However, these templates can be used to capture snapshots before and after change controls.
