### Returns

| Type                                                          | Description                           |

### Remarks

The disconnected Prefab workflows have been removed from Unity because of ambiguity when it comes to nesting and variants. However, disconnected Prefab instances are still common when upgrading Prefabs from projects originating from versions of Unity prior to the introduction of improved Prefab workflows.

If you have disconnected Prefabs you should consider unpacking them completely or turnning them back into connected Prefab instances by reverting the instances.
