Hi,
We have an old GSR12410 running IOS and we want to migrate it to XR. Target release is XR 4.2.4 which is already running in the network.
I have only found documentation to migrate IOS to XR3.8.0,
http://www.cisco.com/c/en/us/td/docs/ios_xr_sw/iosxr_r3-8/migration/user/guide/up38Book/up38upinst.html
So my question is:
Is it possible to upgrade directly from IOS to XR4.2.4 using the same procedure, or do I need to upgrade IOS to XR 3.8.0 first and the upgrade from XR3.8.0 to XR 4.2.4?
Any suggestion?
Thanks!
Jacobo S.
