When upgrading Arista switches which are part of an MLAG cluster, is it necessary to start with the secondary switch ?
In "Arista Warrior", from Gary A. Donahue, he specifies on page 123 to start by upgrading the secondary switch. But there is nothing like that on the official documentation, page 710 (for version 4.13.2F).
Also, is there a way (even if it's not necessary) to force one of the members to become primary ? I found the command primary-priority
here, but the command does not exist on my switch.
