ruby on rails - Migrate an application from 2.3.8 to 3.1 -

-

any advice how migrate app rails 2.3.8 rails 3.1? should go 2.3.8 3.0 , 3.1?

let me know thoughts...

i'm interested in approach gemfile... , bundler. resource link welcome.

thanks.

i'd recommend migrating latest version of 2.3 (2.3.14) before doing anything. once on 2.3.14 should run tests , check logs warnings , fix them. once issues resolved, go ahead , try upgrading 3.1.1. think largest change 3.0 3.1 asset pipeline , can ignore while upgrading. resources, both peepcode , railscasts offer great guides doing want.
