Upgrading to latest version of Ruby

Question

I understand that rvm allows us to run multiple versions of ruby. Are ruby gems installed to a specific version of ruby? Say I upgraded to the latest version of ruby 2.1.1 and want to use that as my default, do I have to reinstall the ruby gems from the earlier version of ruby to this version?

If you use rvm install, you will have to install your gems anew. If you use rvm upgrade, the gems will be migrated if possible.

Check out the RVM documentation:

RVM creates a new completely separate gem directory for each version of ruby. In addition you can separate this further and have a set of gems per project/application/gerbil color... see the gemsets for more details on using sets of gems. [...]

rvm --default use <RUBYVERSION>

For example,

rvm --default use 2.1.1

You can check this. And check out RVM Documentation too.
