推荐答案

我绝对推荐安装 Rails 升级 gem (rails 升级宝石).事实证明，它作为列出和验证所有升级到 Rails 3.0 所需的起点非常有用.

I definitely recommend installing the Rails upgrade gem (rails upgrade gem). It's proven for me to be incredibly useful as a starting point for listing and verifying all the required upgrades to get to Rails 3.0.

一旦您使用 Rails 3.0，您将需要迁移到资产管道，这是另一个很好的起点:http://railscasts.com/episodes/282-upgrading-to-rails-3-1

Once you're at Rails 3.0, you'll need to migrate to the asset pipeline, this is another good starting point: http://railscasts.com/episodes/282-upgrading-to-rails-3-1

这不是一项简单的任务，您需要确保您的代码不会在每一步都出错，但我发现这些工具非常适合让球滚动.

This won't be a simple task and you'll need to ensure that your code doesn't break at each step, but these are tools I've found were great to get the ball rolling.
