Updgrading from FreeBSD 12.1 to 12.2

[@lbutlr]

Is there anything more detailed than the rather sparse information at <https://www.freebsd.org/releases/12.2R/relnotes.html#upgrade> in terms of upgrading to 12.2?

I know I've seen messages in passing about various issues in migrating and since I do not currently have a spare machine I want to proceed with a tightened level of caution (sometime in the next few months).
