License & HDD required for Upgrading IOS to IOS-XR in C12000

1. The hardware is meeting all the prerequisites and I am planning to test IOS-XR but would like to know if any license to be purchased for Upgrading to XR. Because when I checked in Dynamic confiugration tool, I found "Cisco XR 12000 RP Memory Upgrade Kit" "XR-C12K-LCONV".
2. Also how about the HDD that XR requires as the current hardware configuration do not have and even the Cisco document does not specify about HDD.
