Question

我想将我的一个应用程序从rails -2.3.11升级到4.0.0。在做任何事情之前，我只需要计划它而我的应用程序不是那个很大的尺寸，但有一些6/7插件和5/6宝石。

  Existed    : Ruby 1.8.7 + Rails 2.3.11
  Expected : Ruby 2.0.0 + Rails 4.0.0

   For this, I have plan as in two ways like below,
   1).Multi-step process : First need to upgrade app from rails 2.* to 3.* and then
      do upgrade from rails 3.* to 4.0.0
   2).Create new application from rails - 4.0.0 and rebuild old application all 
      features as we have already css, layouts...


   I hope both strategies will take same time.

 Any how, I need some inputs from you all. So please share your thoughts/comments.

     Thanks in advance.

Answer 1

首先，您可以逐步将Ruby升级到2.1.1。然后开始将你的Rails应用程序从2升级到3，最后升级到4.如果你有良好的测试覆盖率，你可以确保你没有破坏任何东西。重写也是一种选择。我建议你阅读这篇文章A Guide for Upgrading Ruby on Rails。
