Cisco 2960x stackable switches IOS upgrade method
Our company have installed a pair of Cisco 2960x switches (Model: WS-C2960X-24TS-L) stacked with FlexStack Plus stacking module.
Currently, they are running IOS Version 15.2(2)E7. We are planning to upgrade to IOS version 15.2.(4)E7 to address some vulnerability suggested by our security department. We will follow the procedure similar/described on the URL: http://www.petenetlive.com/KB/Article/0001002 by copying the bin files to flash1: & flash2: and then reload.
As far as the IOS upgrade procedures are concerned, we have the following questions and clarifications:
Our management would like us to upgrade the switches one by one by copying the bin files, changing the boot system to one of the switch (i.e. Master or member) then reboot first then proceed with the other switch instead of updating both and reload together.
I foreseen that will cause a version mismatch problem and harmful to the stack formation but we would like to know if this is a recommended method of upgrading a pair of Cisco 2960x stackable switches and wonder if there is any Cisco official URL/documentation general prerequisite/requirement pointing out that customer should upgrade the whole stackable logical unit as a whole and reloaded together instead of doing it one by one.
Thank you so much for your technical advice/recommendation in advance.
Regards

You may also want to look into using the archive download-sw and archive copy-sw commands which is a cleaner upgrade process then the one in the link. Especially for stacked switches.
