If I used xml in the store it would probably be easy but it's an sql store to complicate matters.
I'll maybe try just duplicating it and trying to build to see if that works,
Thanks,
Many Thanks

I can change the attribute name in a new data model, but can I then remove the old models and just leave the mapping models to deal with upgrading the file?

This didn't appear as an error in Xcode 3 which I was using, and didn't create a problem using the app. Now in Xcode 4 the model won't even open due to this error. I have got a version of Xcode on a 10.6 machine I can use so I have created a new model version that changes the attribute name to 'ideaDecription'.
