Thanks.

It is possible, but you should do good testing and inform the people
onsite, so that they do not accidently remove power, while updating.

If I do remote updates, I use the "mypackage" feature in ADK and
install a preconfigured /etc/network/interfaces file. You can put
everything you need in mypackage, it will be overwriting existing
files.
So create a ready to go image and simulate the update locally.
Make a backup of an existing device via cat /dev/mtdblock1 >
backup.trx. Flash it on a local device via mtd -r -e linux
backup.trx linux. Set the needed nvram values to the device. (do not
blindly use everything, just use the stuff you need to access the
test device).
Then flash your new FreeWRT image via mtd. After that, login in and
commit the SSH key to the fwcf partition. (fwcf commit)
You can put a public key into the image and even the ssh-host-keys
if you like.
There exist no OpenWrt->FreeWRT scripts, which just use the
information of the old stuff and are creating ready to go
configuration for FreeWRT. I do not plan to write something like
that.
good luck
Waldemar
