Rails 3.1 without breaking

Rails
1

Hi, I’d like some help to install rails 3.1 without breaking old
projects
that use rails 3.0.9.

If I install rails 3.1, will it delete rails 3.0.9?

I don’t understand much about it, but I think all my gems are installed
in
the same gemset.

Or, if it is easier, simply install rails 3.1 and update old projects to
it.
What I mean is, can I just follow the railscast about rails 3.1 or are
there
other stuff that I have to change so that old projects can work from
3.0.9
to 3.1?

Thank you,
Rodrigo

Use rvm for this, then you can install seperate versions of Ruby,
Rails and other gems for each application.

Oh, are you using rvm already? If so just start a new gemset for the
rails 3.1 app.

Using a new gemset you can keep your old projects working and update
them when convenient by updating the app and the gemset. I find it
best to have a gemset for each app, then they are fully independent.

Rodrigo, if you’re using Git or another source code management system,
then I would recommend creating a branch for your Rails 3.1 development.
Furthermore, you can
use Gemfile for your Ruby gem dependency management.

Good luck,
