初めての Rails アプリを Heroku にデプロイしようとしています。認証にデバイスを使用していましたが、ニーズが変わったので削除し、現在はソーサリーを使用しています。
すべてがローカルで機能していますが、デプロイ時に DB を移行するときに次のメッセージが表示されます。
Running `rake db:migrate` attached to terminal... up, run.5220
DEPRECATION WARNING: You have Rails 2.3-style plugins in vendor/plugins! Support for these plugins will be removed in Rails 4.0. Move them out and bundle them in your Gemfile, or fold them in to your app as lib/myplugin/* and config/initializers/myplugin.rb. See the release notes for more on this: http://weblog.rubyonrails.org/2012/1/4/rails-3-2-0-rc2-has-been-released. (called from <top (required)> at /app/Rakefile:7)

Devise についての言及が残っているようには見えません。gem を削除した後に、このような問題に遭遇した人はいますか?
ありがとう！
