Does the current version of High Sierra (10.13 17A330h) support Migration Assistant? I've installed it on an old MacBook, but intend to upgrade to a newer MacBook. I would first of all install High Sierra on the new laptop, then migrate my existing data to it from the old one. Ideally I'd use Migration Assistant, but I don't know if it's available in High Sierra beta releases. One way to find out is to just do as I describe and hope Migration Assistant pops up, but it would be nice to know ahead of time.
It is avaiable. I've used it to recover disk failture because of High Sierra installation for multiple times.
