Earlier quoted context omitted.
Have been on it since beta 3 or something. This has been one of the more smooth transitions, no dev tools broken, and only few apps had some quirks that I filed bug reports for, which are now fixed. The APFS change really isn't something you are likely to hit, heck you'd have to go out of your way to make it a problem. Deffo recommending it :) Speed ups are nice!
Do you know if the APFS conversion affects Bootcamp at all?
So it looks like that the conversion does confuse VMware Fusion at the moment. Not aware of any other issues with Bootcamp.
