I have a Cisco 4500x-32SFP (with Enterprise License) with cat4500e-universalk9.SPA.03.04.04.SG.151-2.SG4.bin ios and i want to upgrade it to cat4500e-universal.SPA.03.11.03a.E.152-7.E3a.bin which is suggested by cisco :
- if i want to do this upgrade, do i lost my license key? can i perform an upgrade safely without any worry about license key ?
- i just do the simple upgrade process?
