IOS install mode vs bundle mode

StackWise - IOS upgrade switch reboot sequence


When choosing between IOS [install mode and bundle mode](/ios-install-mode-vs-bundle-mode), the following should be considered in an environment where [Stackwise](/stackwise-election-process) is being used.

When used in conjunction with StackWise:

- all switches in the stack should be configured with the same mode
- all switches in the stack should have the same license as the active switch
- when upgrading the IOS in install mode, simply upgrade the active switch, and all switches will be upgraded
- when upgrading the IOS in bundle mode, the IOS file must be copied to each switch in the stack
