Cisco Catalyst 9300/9500 IOS upgrade - cat9k bundle to install mode

IOS upgrade in bundle mode to install mode. Will also work if a switch is in install mode already. NOTES: There are two modes for IOS upgrade : bundle and install mode Benefits using install mode: - Booting the switch in Bundle mode consumes more memory than the Install mode because the packages are extracted from the bundle and copied to the RAM. - Auto-upgrade feature is disabled by default and is not available in the Bundle mode. One thing to note, all switches in a stack has to be in the same adding a switch in a stack with a different mode, it will prompt an error
