    Hi everybody.

    Does any recomendation about upgrading XOS on MLAG peers? Should I disable ISC link between peers or it just an ordinary upgrade like download/install/reboot?

    Hi,

    There is no need to disable ISC link between the MLAG peers. Please go ahead and upgrade the switches normally like download, install and reboot.

    I've done it in maintain window. You can reboot MLAG-peer one after another without any network outage if you network well designed.

    Hi eyeV,

    You can load the EXOS image on both peers and install it, then reboot one peer and wait for MLAG peer to get in sync/up. After that, reboot the other peer.

    I had to do that (in a MW) for about 30-40 MLAG pairs (60-80 units) and worked without any issue.

    During the process, the peers will be temporarily in different versions and that won't be an issue.
