My Organization have planed to upgrade our switchs runnin CumulusLinux 2.x.y to 3.7.0.
I would like to know the best practice, should I upgrade one switch and the other just after or can I upgrade one switch and let the second on the old version and upgrade it one week later for example? just the time needed to confirm everything is woirking with 3.7.0 version
What do you think about it ?
Thank for your help!
