Cisco IOS version and start-config change
Posted on 2014-10-28
We have a Cisco 3560 Fast Ethernet switch that we are replacing with a 3560 Gigabit model. The FastEth switch is running IOS version 12.2(44)SE, and the newer, Gigabit switch is running version 12.2(53)SE2. I'm considering a tftp transfer of the start-config from the old switch to the new, but am unsure about whether the IOS version would be affected. I don't want the older version to replace the newer one.
I suspect that the IOS version would be unaffected by the starting configuration change, due to startup-config residing in nvram and ios residing (compressed) in flash, but need more info before proceeding.
Any help would be appreciated.
