[DASTAN]

we have several stacking on the network with 15.2 version, we are planning to swap-out some of them and at the same time update the version. what is the usual practice to do this?

Hi Dastan,

That's correct. The whole stack must be rebooted for it to use the new version of code.

[DASTAN]

got it! meaning the whole stack should be reboot for the new code be applied on the set partition? my unit is X440. no way to upgrade without interrupting the traffic. right?

thanks a lot sir! big help really!

Good morning Dastan. Yes when you download the image to the stack it will update all of the switches in the stack. The command you listed is the command you need to upgrade the switch just do it to the master. After the switch downloads the code it will ask you to load it say yes that sets the new image container to be the next one used on a reboot. You then need to reboot the switch for it to be active. You can use the reboot command to reboot right away or build out that command to reboot at a particular time. Hope that helps. P
