The development process under Kodo 3 is slightly different than it was under Kodo 2. For example, the familiar schematool has been replaced with the more powerful mappingtool. You should take a moment to read through the revised Kodo tutorials and the Reference Guide to familiarize yourself with the new processes under Kodo 3 and the new features available to you.

Also, be sure to read the release notes for all Kodo 3 releases, including the betas. The Notable Changes section of each note lists topics you should be aware of in your migration.
