Hi guys,
I have a stack with two x480 running XOS 15.3.1.4
Is it possible to upgrade the two switches in the stack one after another so that one of the switches is allways forwarding traffic?
Thanks,
Thomas

Welcome Thomas This document was created for a customer that had a DC in an EAPS ring. If you don't have an EAPS ring then you may not need to disable the port as indicated in the document.
Just download the code to the opposite image container. Tell the stack to use the new code then follow the process for powering done the node and disconnecting the stacking cable. The whole process should only take approx 5 min.
Good luck and let us know how it works for you.

Hello Thomas
We do not support hitless upgrade using ISSU within the stack. I have come up with a partially manual way to perform a hitless upgrade to the stack. This assumes that all devices that are connected to the stack are connected to each of the nodes.
If you are interested in how you can do this please see the document at this link https://www.dropbox.com/sh/f66b3kfoii2t573/AAAWE5Idb4W01b-SEWnrgda9a?dl=0
I hope this provides a solution for you.

Hi Thomas, This is not possible. Also with hitless extreme may not support Sync of bgp, ospf routes. From which exos version you are upgrading code ? As it is x480 I assume you must be using bgp/ospf ... There is lot of code changes between 12.6 to 15.x
