[Zope] Migrating a legacy Zope2 app to use buildout.

Hello, Currently, we have a Portal that was built starting in 2004 before buildout was available, so our development method has been to export and import from the Zope2 WebUI for deployment. That's been a real pain and since we've automated the rest of our infrastructure with Chef we'd like to be able to do that with Zope. So my question is does anyone have pointers for migrating an app that mostly lives in the ZODB to a build-out style architecture that we could control with Chef? I see tutorials on starting a new Zope 2 app from scratch with buildout but nothing on migrating an older one to build out. For example, how would we create objects like MySQLUserFolders etc from buildout? Thank you in advance. -J
