Hi, I'm in the process of upgrading 12K IOS XR from 3.6 to 4.2. But according to cisco upgrade path its seems to be from 3.6 -> 3.9 , 3.9 - > 4.2 ( http://www.cisco.com/web/Cisco_IOS_XR_Software/index.html#XR12000) . therefore i'm wondering that whether i can do turboboot . but there is no reference regarding the minimum rommon required to load the 4.2 IOS XR in turboboot ( min required is 1.24) . Also to upgrade the rommon there is no package available on the download section ( archive also doesn't have package) .
Anyone having previous experience on 3.6 - > 4.2 upgrade ? Thanks & regards _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
