Hi Jerry,

I did try making a mapping model (this is something I've done in the past in other apps) but I got the same error message. Is the idea that the auto-migration magic will pick up the mapping model and use it, if it finds it?

Many thanks,

Martin

Creating a do-nothing mapping model just takes a few minutes, certainly less time than you spent writing and editing your post :)  If you've not fixed this yet, you should give it a try.
