How to software upgrade 4 x450 in a stacked config

We have 4 x450 switches stacked here. I would just want to ask for the procedure on how to do xos upgrade for switches in stacked configuration? Do I need to break the stack, upgrade each node then rebuild the stack? Or can I upgrade all those 4 switches in 1 go in their stacked config?

thank you,

You can download the software image from Master node and it will automatically install the software on all 4 slots when in stacking.
No need to break stacking.

@ Parthiban is absolutely correct. However, first you need to confirm if all the slots in stack are booted on same partition using the command "show switch".
thank you for your answers!
