Gents,
I've to upgrade the IOS of 4500X and 4948E switches but couldn't find the clear steps in Cisco's official documentations.
Versions selected to be used are:
(1) 4500X = 3.3.6E
(2) 4948E = 15.2.2E6
* Please note that I'd like to upgrade without ISSU as it sometimes causes issues on the catalyst series.
**Kindly, also let me know if the ROMMON is also required to be upgraded on both the nodes.
Looking forward to hearing from you.
