I've put that into my TODO list -- out of my curiosity I'd like to see where it does that (my hunch is that it's early in the boot, page tables are not set yet, using 32b part of regs only).
Yeah, do a backup for sure. It would be even better if you can test this in VM first. I'm using this approach when I want to have cleanly installed system ; basic installation is done from old running system. With ZFS on root you can even prep boot env without beadm.
When it comes to config I have this one liner to save etc:
But it's still nice to have all files at hand by some means (/old, external backup..).

find /etc /usr/local/etc/ -depth -print | cpio -oaV | gzip -c > `hostname`_etc.cpio.gz
