Migrate from rails 2.1.1 to 2.2.2

Question

I am working on a project using rails 2.1.1. With the new release of 2.2.2 I want to migrate to the new version. Is there anything I need to change to migrate my 2.1.1 controllers, views, and models?

Answer 1

Don't forget to run the update Rake task

rake rails:update

That will go ahead and make sure it updates any scripts and configs to reflect 2.2.

Once you have 2.2 installed, issue:

rake -T

to view the available tasks, double check it's there and go ahead and fire it off and you'll be up and running.

Good luck!

Answer 2

There aren't any major changes in the way things are done. Here is the list of deprecations

Of course the best way to quickly discover changes is to have a good test suite in place. If you don't have that, I suggest dropping 2.2 into vendor/rails and clicking around the site by hand.
