Bruce Mah is requesting comments on his FreeBSD Migration Guide. The guide explains the release process and new features in 5.3. Remember this is a draft, but if you have feedback join the thread on freebsd-current.com to see what you want to hear. The migration guide explains how to upgrade from 4.x to 5.2.3, and how to use the new features of the new version of the open-source operating system. The guide also explains the migration process for the new versions of the operating system.”]
