Topic: Need to update rvm

Not sure this is the right place. But I need to update my rvm as:

$ rvm package install readline
$ rvm remove 1.9.2
$ rvm install 1.9.2 --with-readline-dir=$rvm_path/usr

Can I do this without loosing my gemset? And if I export the gems will they be "safe" when doing this action above (and then import them again after)?

Or how can I do this without disturbing the running server to much?
