You'll need to update to a middle version before you can hit 2.6.2 - something between 2.4.x and 2.6.



Please update to 2.6 first.


"ePMP radios running System Release 2.1 or earlier cannot be directly upgraded to System Release 2.6.1 or later. Please upgrade to System Release 2.6 first, then upgrade to System Release 2.6.1 or later. Stepping through System Release 2.6 is not required if the ePMP radio is running System Release 2.2 or later."
