# Installing multiple versions of sage

Basically, I want to install multiple versions of sage without having to recompile for each version. Say I have sage-5.5 in a directory named "sage." Is there a way to use my existing sage to upgrade to 5.6-beta2 without having to rebuild everything and to still retain both copies?

EDIT: I tried sage.misc.package.upgrade, but that didn't work with the beta.

Well, you could just make a complete copy of your sage-5.5 (maybe named, sage-5.5-to-be-upgraded) and then upgrade that. Or? Maybe I'm missing something to your question.

I was trying to do it with the beta, I'm not sure how to manually upgrade sage.
