Special:UsabilityInitiativePrefSwitch should show a message if the user had a monobok.js but doesn't have a vector.js. In pseudocode: {{#ifexist: Special:MyPage/monobook.js | {{#ifexist: Special:MyPage/vector.js || You had [[Special:MyPage/monobook.js|custom javascript]] in monobok. You may want to [[Special:MyPage/vector.js|copy it for vector]]. }} |}}
