@emord @czue @esoergel 
either a lazy migration in the wrap class or an explicit script. i've been meaning to pose this tradeoff to the dev team (was the example i chose on "dev discussions"). i think i prefer the script approach since it's a one time inconvenience but doesn't leave migration code cluttered around, though would be open to arguments the other way.
