Several people have told me they are playing with DBIx::Class::Migration from the github repo, but have all run into the same questions. Rather than keep repeating my answers, until I can get that code on CPAN here's a link to the wiki that has links to the internal tutorial, which you might not see due to the way github is organized. You'll need to navigate with the brower back button for now, but this is just temporary until I can work out the patches to DBIx::Class::DeploymentHandler with the author, and move this to CPAN. Until then I hope the tutorial is useful!
Also, a link to the FAQ, which has answers to the most common error messages I am hearing about.
