Replace game object in scenes with new prefab.

[acoppes]

This could be useful when there are multiple scenes with a similar object and you want to extract a prefab from one of the scenes but also fix all scenes to use the same prefab.

How to identify it is the same object? well, one option could be to find objects with same name and same structure (mono behaviours, children objects, etc, for example), maybe it could be serialized and check serialized versions.

Once detected, create prefab from one scene, switch all other scenes to use that prefab using replace utilities.

It could be done in two steps, like creating the prefab manually, and then selecting the prefab and call the replace game objects that are not prefab instances but match the prefab serialization with new prefab.
