How Will Gutenberg & WordPress 5.0 Affect ComicPress?

Im a bit disturbed this hasn’t popped up yet (I’m not getting any results when I search up “Gutenberg” in this forum) But how exactly is Worpress 5.0 going to affect the comic press plugin? The annoyingly vague language of WordPress’s official statements allude that plugins will be more or less eliminated from the structure of Gutenberg, and since that’s 80% of my site is it just going to wipe out all my saved media and I’ll need to start from scratch?

I wouldn’t be upset by that since my site needs an overhaul anyways, but is there a way I can save the old version of my site first just in case Gutenberg is too much of a hassle to work with? How would that be possible?

(And yes I’m aware I can keep using the current version by downloading it as a separate plugin, but I am open to giving the Gutenberg beta a try, I just want to know if there’s a way I can save my current site as a backup in case Gutenberg wipes out everything and I don’t even like it)
