Rails 3 upgrade

I’ve read today another article on upgrading to rails 3 from a rails 2.x app, and this made me think, since I did not yet get my feet wet with the new (now almost old) release.

I’m still working a lot with apps built on rails 2.x (and even one still on the venerable rails 1.2.6 ), and even if I’d like some of the new goodies I’m not really feeling the pain in using the old release, at least not enough to justify the transition. Anyhow I’m looking to do some new development on rails 3 and maybe I’ll even start porting a very old app (actually the first or second I developer on rails) that I have still lying around (I think that when I’ll do it, this suggestions will help a lot).
