How to upgrade IOS image on cisco multiple devices same time?
If you have some SNMP / Remote management tool in your network. You can do it at a time. But in your case what i suggest you is you can connect your desktop/laptop to 1 2960 access switch and start the tftp server and you open multiple windows to login in to all 2960 switch (9 switches) and do the IOS upgrade in a little gap but not simultaneous. Do not do the laptop connect switch or the core switch. You will lose the connectivity while restarting. Then swap you PC to someother switch to make that left out 2960 upgradation and the core upgradation. Restart 2960 1st and then the core or entire thing vice versa
