    Hello Dave,

    Can you add more information about the statement in the note at the bottom of the section. Say EAM is installed, and you install the original way by upgrading master first, the backup is running operations - and during upgrade if control tries to fail back to primary, its either not installed or in the process of upgrade - so it probably wont take control. 

    Alternatively, if you upgrade on backup node first - if during upgrade somehow primary failsover to backup node, its still in the same pickle - trying to move control to a node that is in the middle of an upgrade. 

    I am sure i am missing something; can you please comment.
