2920 stack - software upgrade

[HP-Browniee]

Hi guys

Just a little question:

I have a stack of two 2920 switches. Is it possible to do a software upgrade without downtime? Asuming all clients are connected redundant. Or is a full reboot of the whole stack the only solution?

Thanks in advance

AFAIK a complete Stack reboot (with the boot system command invoked through CLI) is required to finally run the updated code...so this means that a little downtime should be expected and you need to plan a proper maintenance window to perform a software upgrade on stacked 2920 Switches with a minimum disruption.
