I’m trying to upgrade a Rails 2 application to Rails 3.

rails -v

outputs Rails 3.0.0.rc — so, that part’s good.

But…

When I do:

rails server

I just get the help

So I tried 

script/server

and I get:

=> Booting WEBrick
=> Rails 2.3.2 application starting on http://0.0.0.0:3000

I’ve done a global replace in the application on ‘2.3.2’ but it STILL says it’s a 2.3.2 application! Why is that???

I’ve followed a bunch of tutorials on this upgrade path and no luck yet. But I’m really stumped as to what keeps making it think it’s a 2.3.2 application.

    Just to make sure it’s found if someone else comes along — I had to unfreeze my application. It was automatically using the rails version frozen into the app.
