I imagine this probably isn't very hard (if hard at all). Since updating to A9LH a year or so ago when it was new and AuReiNand was the way to go, I haven't bothered to update to the latest version of Luma. But I'm starting to worry that staying on AuReiNand could one day be an issue, or that perhaps Luma has something more going for it (does it? If so what?) Anyway, for the sake of avoiding any possible future issues and being up to date with the latest and greatest. Is there an easy way to upgrade from AuReiNand to the latest Luma? If so, what do I need to do? Much thanks!
