If you wish to swap out one subVI for another, unload your VIs, rename or relocate them in the file system, then reload. If you want to rename a subVI, do as Scott suggested and Save As. If you are changing the connector pane pattern, you will need to visit the callers since LV doesn't want to mess up the wirings. We've often talked about the ability to save a recipe with the new connector saying where the old terminals map to, but for the moment, you can usually avoid this by choosing a connector with a few spares.
