How to upgrade to rails 2.0?

I wanted to ask if anyone has any links to online resources or
tutorials that teach you how to upgrade to rails 2.0?

Cheers,
Elle

Thanks guys. Here's another question:
I used this command:
rake rails:freeze:edge TAG=rel_2-0-1

But now when I try to start the server I get this error:
...vendor/rails/railties/lib/initializer.rb:159:in
`require_frameworks': no such file to load -- active_resource
(RuntimeError)
from /.../vendor/rails/railties/lib/initializer.rb:88:in `process'

from script/server:3

Could I ask for advice on what the problem is?

TIA,

Do it again (sounds stupid but it's true). The first time you run
this, you're running the rails 1.2.x version of the rake task, that
doesn't know about activeresource (and so doesn't download it). The
second time you're running the rails 2.0.1 version of the rake task,
which does know about activeresource.

Run it again and this time, when trying to start the server I get a
different error:
/.../vendor/rails/actionmailer/lib/action_mailer/base.rb:354:in
`method_missing': undefined method `server_settings=' for

        from script/server:3

My config/environment.rb has the following:
65 ActionMailer::Base.delivery_method = :smtp
66
67 c = YAML::load(File.open("#{RAILS_ROOT}/config/config.yml"))
68 ActionMailer::Base.server_settings = {
69 :address => c[RAILS_ENV]['email']['server'],
70 :port => c[RAILS_ENV]['email']['port'],
71 :domain => c[RAILS_ENV]['email']['domain'],
72 :authentication => c[RAILS_ENV]['email']['authentication'],
73 :user_name => c[RAILS_ENV]['email']['username'],
74 :password => c[RAILS_ENV]['email']['password']
75 }
76 CONTACT_RECIPIENT = c[RAILS_ENV]['email']['contact_recipient']

Should I run it again? or is this a different problem?

Hi, you can try using the following instead of server_settings:

smtp_settings

Good luck,
