We are in the process of upgrading to IOS-XR in C12000. I have gone through the documents that the basic hardware and software prerequisites should be met for upgrading to IOS-XR.
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.
"http://www.cisco.com/en/US/docs/ios_xr_sw/iosxr_r3.2/upgrade/guide/up32sing.html#wp1121414". HDD is only required for CRS in XR releases and not on GSR?
thanks in advance
1. No upgrade licences are needed to change from IOS to IOS XR on the c12000.
2. HDD is optional for XR on c12k.
