I'd never seen the panel before right now. I like the skin. I suppose I or others could create a script for you presuming a good backup system with good documentation (or even without it, but that would be a lot harder), but it could get more expensive than doing the migration by hand.
Though I no longer do last mile I've been in the ISP business since the 90s; and was one of the early members of Avi Friedman's the List where early ISPs shared many discussions on many toopics.
Feel free to email me if you'd be interested in development on the project.
