Changing application version

I have an application on Rails 2.0.2 and I want to update it to Rails 2.3.4.

Do I need to do a new application and I only copy and paste the necesary files?

Or, Do I can to do another thing?

I tried with: rake rails:update, but nothing happened.

Does anyone know how to do this?

Did you edit your environment.rb to use 2.3.4? Next, if you installed Rails into vendor, then you’ll need

to remove it to use the system installed gem.

Good luck,

First make sure you are using a version control system so you can make changes and back out if necessary. (I prefer git, some like svn etc.)

Next make sure your test suite is comprehensive so you can be sure you have not messed anything up.

Install the rails version 2.3.4

Edit config/environment.rb so you have a line like RAILS_GEM_VERSION = '2.3.4' unless defined? RAILS_GEM_VERSION It should currently reference the old version.

Then do rake rails:update, it should update boot.rb and probably some other files

Commit that version to your version control system

Run your tests
