I fully agree that doing a migration script that is anywhere near decent 
for all possible switch configurations is a big undertaking.

I think the bare minimum to do before doing a breaking change like this 
is to have warning messages on sysupgrade (both via CLI and web 
interface) that stop the upgrade until the user has acknowledged the 
warning.

So that people that don't follow mailing list or forum won't learn the 
hard way they have just hosed their custom switch config (if any), and 
that their device is now unreachable and useless until someone goes 
there and throws an ethernet cable or serial to reconfigure it.

If you give a warning, people can just prepare an image with the Image 
Builder where they add manually the config files to replicate their 
setup in a sane way with DSA and send that image instead.

Or for the very least come ask in the forums what to do.
