As you said that you want to upgrade the rails version of the current application, you have to follow a few steps:

Before that, just check the following settings:

• Check your .rb environment settings
• Transfer the .rhtml files to html.erb
• Check for any changes to route.rb that might be required, given that ROR 2.3.4 made route determination easier.

• , SCM : git, svn, () cvs. .

• form_tag, <%= form_tag :action=> "search" %> becomes <% form_tag :action=>"search" do %>

• <% = end_form_tag% > <% end% > .

, :

• $sudo gem install rails

• : : 1.2.3 RubyGems 1.3.1 ( GemRunner), activeresource, Rails 2.3.4 :

  $cd ~/src $ rails rails23- $ cd rails23- $ rake rails: :

• $cd ~/src/app_to_upgrade $ git checkout -b rails23 # , git

• Rails

  $rm -rf / $ mv ~/src/rails23-app/vendor/rails vendor

• /boot.rb public/javascripts/*. application.rb application_controller.rb

  $rake rails:

• config/initializers/*. , .

  $cp -r ~/src/rails23-app/config/initializers config
