You can unpack new sets on top of old sets. There's daily builds on:
https://nycdn.netbsd.org/pub/NetBSD-daily

You can cd /; tar xzpf /path/to/set.tgz

It will leave a small amount of things behind, postinstall can collect
them, as long as you keep upgrading.
It isn't safe to run postinstall on a downgrade.

For RPI, your kernel is on another partition and not /netbsd, so it's a
bit more involved, but I think you can mount it with mount -t msdos and
replace it.
