# DLM_OT_migrator_remove_original class update (2026-03-10 16:23Z)

_**User**_

Update the DLM_OT_migrator_remove_original class in T:\Dynamic-Link-Manager\ui\operators.py to delete the collection containing the original character instead of just deleting the armature object.

Current implementation:
```python
def execute(self, context):
    orig, rep = _get_migrator_pair(context)
    if not orig:
        self.report({"WARNING"}, "No original character selected")
        return {"CANCELLED"}
    if orig == rep:
        self.report({"ERROR"}, "Original and replacement cannot be the same object")
        return {"CANCELLED"}

    name = orig.name
    try:
        # Remove from scene
        bpy.data.objects.remove(orig, do_unlink=True)
        # Clear the property
        context.scene.dynamic_link_manager.original_character = None
        self.report({"INFO"}, f"Removed original character: {name}")
    except Exception as e:
        self.report({"ERROR"}, f"Failed to remove original: {e}")
        return {"CANCELLED"}
    return {"FINISHED"}
```

Change it to:
1. Import and use `collection_containing_armature` from `..utils` to find the collection
2. Delete the collection (which removes all objects in it)
3. Clear the original_character property
4. Report which collection was deleted

If no collection is found, fall back to just deleting the armature object.
