Thanks Grzegorz, down time window is the problem to go for 2 steps . rommon upgrades are in the FPD package but if i want to do the turboboot there is no way that i can install the new pie c12k-fpd.pie-4.2.4 on 3.6.2 and upgrade the rommon . is there any package that i can copy and upgrade the rommon like CRS .Cisco document mention about 3.x to 4.x with c12k-upgrade.pie-4.2.4 package but still confusing about direct 4.2 upgrade.
