Hmmm interesting idea. My concern would be wiping it completely out and something not restoring and then I would be left to rebuild the system from scratch. I had to do that when I went from Vera Lite to Vera+ a while back.
I thought I’d share my experience migrating from Vera Edga to Vera Plus: Flawless !! Did a backup of Edge, plugged in Vera Plus, restored and everything appeared and works great !
