How should I upgrade an old version of Ruby Enterprise Edition?

We have a legacy system running a version of REE that is almost 3 years old. The version we're using has some issues that have been patched in later versions, so it would be nice if we could upgrade to a newer version.

This is the upgrade recommendation in the documentation (it was compiled from source): http://www.rubyenterpriseedition.com/documentation.html#_upgrading.

However, does that just overwrite the old stuff with the new stuff? I want to keep all of the currently installed gems (and their corresponding binaries). I don't want any new gems: I don't want it to install a new version of rails, or any of the dozens of other gems the latest version tries to install.

Using rvm or rbenv might make this easier for you. In the case of RVM which I'm more familiar with, the process would be to capture a list of currently installed gems, such as the output of gem list and transform that into a Gemfile that bundler can use to reinstall them.

Upgrading with RVM is relatively safe since the new REE version will be installed in a separate directory structure and you can revert to your previous version if something goes wrong by abandoning RVM or switching to the system Ruby.
