Great, Thanks for the update.
Now you can upgrade to your desired code/firmware on both the flash partitions (if not done yet) and set the boot system to primary/secondry. This will ensure that the specified partition is booted when the switch goes for a reload /crash next time.

conf t
boot system flash primary/secondry.


Thanks
