If you create DVD or BluRay, do NOT un-install Encore CS6
CS6 is the final Encore http://www.adobe.com/products/encore/faq.html

Also, Cloud is rental only... if you stop paying the monthly fee, the programs stop working
CC and CS6 are independent of each other, so you can have both versions on your system or you can uninstall CS6 and CC will still work.
