how to upgrade a rails 2 plugin to rails 3?

---

This handbook will tell you exactly what to do:

http://www.railsupgradehandbook.com/

Upgrading a legacy rails 2 -3 is a tedious task ... many errors will arouse especially if the application is big and old. I would also suggest you watch railscast episodes 225,226 and 226.

Good luck :)

I recommend you this tutorial:

• http://railscasts.com/episodes/225-upgrading-to-rails-3-part-1
• http://railscasts.com/episodes/226-upgrading-to-rails-3-part-2
• There are a part 3 too

There is a plugin available for upgrading rails version. Try this:

Normally it's not that hard to upgrade Rails 2 app to Rails 2. Here is a sample guide:

http://www.railsdispatch.com/posts/upgrading-a-rails-2-app-to-rails-3

The guidelines that applies to apps should apply to plugins as well

If you want to upgrade a 2.x app to 3, there is an episode in Railscast Upgrading to Rails 3 Part 1 which explains about rails_upgrade plugin that help to determine what needs upgrading.

i think you can't upgrade the rails 2 plugin to rails 3 plugin. You can always change the structure of the code suitable to rails 3 coding but that doesn't mean upgrade. You might need to check out the repository if you could find the version suitable to rails 3 for that plugin

You can find a peepcode for that : https://peepcode.com/products/rails-3-upgrade-handbook-pdf

Or the railscasts is very nice too
