Migrate YUI 2 to YUI 3

Question

What is the migration path for upgrading the Yahoo JS & CSS libraries from version 2 to version 3?

Specifically: CSS & fonts, button, TabView.

Any pointers to further information about issues encountered, tips to make it easier, etc would be greatly appreciated.

Different Google searches (e.g. upgrading yui2, migrating yui2) didn't turn up much on this.

Answer 1

CSS Fonts is pretty much 1:1 in my experience. TabView works differently but functionality wise should be equivalent.

Here's a great overview recently posted to the YUI blog that gives you a pretty thorough overview of each component in 2 vs 3.
