Safe to install Visual Studio 2015 Preview side-by-side Visual Studio 2013

Question

Is it safe to install Visual Studio 2015 Preview side-by-side Visual Studio 2013? Can I uninstall VS 2015 Preview if VS 2013 stops working?

UPDATE:

Answer 1

I've had issue with installing nugut packages when I install visual 2015. Before my 2013, I could install nugut packages correctly. After I installed 2015, I can no longer install any nugut package on the 2013 version. it complains that it cannot find the packages. But when i try it on the 2015, it works.
