Mac OS X: How do you handle migrating the app if you need to change the Bundle Identifier?

I recently updated electron-packager from 5.2.1 to 7.0.1. Part of the changes that came with that upgrade was a change in how the default Bundle Identifier was generated Platform: Mac App Store support #233. That ended up causing me a pretty painful breaking change as my app had a space in the name which would get normalized to an underscore (_) in 5.2.1 but a dash (-) in 7.0.1. That in turn broke auto-updating because the new app's Bundle Identifier no longer matched.

The new version of electron-packager has the correct implementation, the Bundle Identifier should never have had an underscore in it, as that is not a valid character according to the spec, but I already have versions of the app distributed with it. Right now, I do not know how I would be able to gracefully handle the Bundle Identifier changing.

Sorry but I don't think autoUpdater would be able to handle this.
