I’ve havn’t run across a brief synopsis via search so I thought I’d throw the question out here. As my first real application is still a work in progress I suppose I should upgrade to 2.0 before I finish it off. (especially as I’ve just seen a couple good tutorial on implementing restful authentication in a 2.0 enviornment and would prefer to follow them lock-step) Are a lot of things going to stop working? (Im not using any scaffolding). How will I get the new features like initializers into my existing projects? Do I need to rename things with rhtml extensions .html.erb ? Will I need to change the format of my migrations to the new way? Would it be a good idea just to scrap the existing application and cut and paste code after regenerating controllers and models? (sounds like a lot of work!) ---

Thanks for the quick replies Ryan but I missed the answer on how I get the new features like initializers into an existing application. I poked around on the [rails.org](http://rails.org) site and found the directions I hope will work. I’m sorta wary about doing it but I guess I’ll take the leap. [http://wiki.rubyonrails.com/rails/pages/HowtoUpgrade](http://wiki.rubyonrails.com/rails/pages/HowtoUpgrade) ``` * gem update rails -y ``` or ``` * sudo gem update rails -y * Open your_project/config/environment.rb and change ``` RAILS\_GEM\_VERSION to point to the version you just upgraded to \* Run rake rails:update from your project’s root directory \* Verify that any tests you may have written still pass ---

Hi Tom, I updated our rails app to 2.0 in December and apart from fixing deprecated issues and patching some third party gems there wasn’t much to do. To get initializers to work, all I had to do was to create and initializers directory under config and drop in my .rb file. To be fair, we don’t use the features that Ryan mentions but I can’t say that we’ve had much other than a smooth transition from 1.x to 2.x. Chris On Jan 9, 11:00 pm, Tom N.

What specifically about initalizers do you need? On Jan 10, 2008 9:30 AM, Tom N.

There are a few things that will break. If you are using scaffolding of any sort, you’ll have to do some work. If you’re using Rails pagination, you’ll have to decide on Rails classic\_pagination or will\_paginate. I posted a blog entry on some of this stuff: [http://calicowebdev.com/blog/show/17](http://calicowebdev.com/blog/show/17) I upgraded an app that was pre-REST to 2.0 and made it RESTful in about a day. YMMV. 🙂 ---
