I don't think there is a migration guide from 2.X to 3.X, other than the specific information in the release notes.
If you start reading CHANGES.txt at version 3.0.0, and then each later release's notes after that, especially the sections "Changes in backwards compatibility policy", e.g. for 3.0.0: <http://lucene.apache.org/core/4_0_0/changes/Changes.html#3.0.0.changes_in_backwards_compatibility_policy>, and "API Changes", you'll get a good picture of the changes you need to make to your code.
