IF all of the below are true:

1. Both old and new are built with Crochet.

2. The size of the system partition is the same, and the packages, if
any, that are included are compatible.

3. Local changes are all saved to the mounted configuration directory,
which is copied to RAMdisk on boot.

THEN

You can replace the system image with a new one, OR you can copy the
/cfg directory from the old to the new image, and perform the update
this way.

I do this with a production distribution.  Note that all three of the
above have to be true or unexpected things are likely to happen.

Crochet builds typically do not have a "ping-pong" system partition
(that is, two of them with one set to be the active, booted one) so you
can't update "in place" without special consideration.  If you DO build
with a "ping-pong" configuration, and have a system that can boot from
the "active" set one, then you can do it this way as well (load the new
system image in the not-active system partition, change the active,
reboot) but the above three considerations apply (the new build has to
fit in the space available, basically.)
