I'm migrating from a 5530-24TFD & 5520-48T-PWR stacked to a 5632 and 5698 stack. Answered my first question by reading some.
Also my 5500 series stack is at 6.3.3 and my 5600 stack is at 6.0. I was thinking of making a 5530 base and having it auto-upgrade the 5600 stack, but I read that the 5600 stack must be set as base. Is that a rule, or just a suggeston? I figured it would be easier than going through the upgrade bit again.
