Using Aperture and Photos together

Will all my edits I've done in Apeture show up in Photos after the initial move?

Yes.

if I understand correcting new edits will not show in Photos if made in Aperture. I am certain from all reviews Photos will not be sufficient for the sort of editing I do and am wondering how easy it will be to move between the two.

There is no way to move between the two. You export from Aperture - thereby baking in the edits, and then import to Photos. Bluntly, if you're a heavy Aperture user Photos has nothing for you.
