I am planning to upgrade IOS-XR from the current (very old) 3.6.1 to 4.1.2 (seems to be stable).
I would like to know:
1. Can IOS-XR be upgraded directly from 3.6.1 to 4.1.2 or I will have to upgrade to intermediate image then do final upgrade to 4.1.2
Because in Cisco IOS-XR General information page, upgrade procedure to 4.1.2 is given only from 3.8.x-4.0.x.
2. When I upgrade to 4.1.2 using "p" image not "px", but when I look into SMU, all are represented as "px". But I think a node should only have same form of packages (pie and smu). In this case, I am not able to find SMU with "p" package. What can be done in case of SMU for 4.1.2 "p" package?
