Right-click on the figure>Transfer Active Morphs will do the same as AutoFollow for the weight-mapped figures (not AutoFit, that is for converting a fitted item to a different base figure)

Which product are you looking at? There are AutoFit clones for converting clothes, there are UV sets or image converters for using textures, I can't recall if there are morph transfer tools. I don't think there is a single product that will do everything needed to convert characters, fitted items, and parented props.
