[cisco-voip] Unity 4.x to 7.x with failover upgrade

[Pat Hayes]

Your initial question was:

> My question is do I need to upgrade the failover server?

This is what I labeled option 1.

> Can I just upgrade the primary and once it is up and working with version 7 do a fresh install of the secondary server?

This is what I labeled option 2, and is what I suggested you do, see
initial reply for details.

So, what is it that remains unanswered?
