Upgrading Cisco 500 series stackable switches in stacking mode

[Allwyn Mascarenhas]

Hello community,

My switch model is: sg500-28-k9-g5 to be precise.

I have 4 switches in stacking mode in my setup and I want to upgrade them to a higher level firmware.

Is it recommended that I remove the switches from stacking and upgrade individual switches or can I simply upgrade the master and expect it to pass on the firmware change to others, after all they work as one switch in stacking.

Also if it is just the master I must upgrade then do I have to change the boot code on others and just upgrade the firmware on the master? I got something like from a website.

I have ended here after sifting through the internet.

Thanks for taking the time.

Hi, you may upgrade all the devices while in the stack. You would upgrade the master and it will propagate to the slave unit automatically.
