Can Zurb create some sort of tool or workflow for easier upgrades from 6.3 to 6.4 to 7.x etc? EDIT: Yes! "Migration" is a more correct term than "upgrade" here. Thank you! EDIT 2: As for other full on tools that need to deal with changes to Foundation versions - I'd point to CoffeeCup's "Foundation Framer" and Humane Technologies "Pinegrow" apps - both need to update every time there's a new version. As to how they do that internally, I've no idea. I only know they somehow update the apps. Perhaps the existing site projects break - both are GUI front ends to help the user visualize as they build.
