I have no previous experience with Ruby on Rails. I'm trying to upgrade it from;
[root@server1 ~]# uname -r
[root@server1 ~]# ruby -v
ruby 1.8.5 (2006-08-25) [x86_64-linux]
[root@server1 ~]# rails -v
Ruby 1.8.72, 1.9.2, 1.9.3, 2.0.01, jruby-1.6.7, jruby-1.7.2
What is the best approach for this ? any HOWTOS?
Any support would be highly appreciated.
