Hey @Carl - at the moment there’s not a way to convert a custom legacy app over to the. Dev Dash. Just sharing a prior post with some answers from one of my colleagues here:
That said, just to confirm, your main concern is having the Fulfillment settings and location assignment carry over with a reinstall? You’re right that this would be a bit tricky, and I can’t guarantee anything, but I’m happy to pass along some feedback and look into some workarounds for you if that would be helpful?
