A little practice with stacking mechanics on 3750 Catalyst switches based on the Cisco article http://www.cisco.com/en/US/products/hw/switches/ps5023/products_configuration_example09186a00807811ad.shtml

WARNING: Changing the switch number may result in a
configuration change for that switch.
The interface configuration associated with the old switch
number will remain as a provisioned configuration.

Configure the boot variable to boot the switch with the newly copied IOS:
Switch(config)#boot system switch all flash:/
c3750-advipservicesk9-mz.122-25.SEE2.bin
Switch(config)#exit
Switch#write memory
Verify the boot variable:
Switch#show boot

!--- Master switch.
Config file : flash:/config.text
Private Config file : flash:/private-config.text

Reload the switch and verify that the switch runs the new Cisco IOS software version after the reload:
!--- Reload the switch.
Switch#reload
Proceed with reload? [confirm]
!--- Verify the Cisco IOS software version of the switch after the reload.
