MoveAnnotations method did not work for me. This dimension is not available when editing *Front annotation view via GUI. I think it is not recognized as an annotation by an API.
So far I only found RunCommand method 3135 which opens Select annotation dialog.
Try this method: 2015 SOLIDWORKS API Help - MoveAnnotations Method (IAnnotationView) . Example: 2015 SOLIDWORKS API Help - Move Annotations to Notes Area Annotation View Example (VBA)
