Here is my problem:
I've been working on a RoR project for a while (its quite big
project), but have to stop the work on it for some half a year. Now
I'm back on it and I'd like to switch to the newest version of Rails
(my project is using Rails 1.2.6). Any tips how can this be done in
some painful fashion? Plus I would like to pick the Rails 2.1 on the
way as easily as possible. Any tips here, too?
