The only thing that I can add of value is that our VLAN subnet sizes will not change. They will remain at /22's. but now that we are on the 7.4 code, we will leverage "interface groups" to provide enough IP space to our main SSID.
We are not using VSS. We bought HA controllers because they were so affordable and in the 7.4 code they can function in N+1 mode (haven't tested yet; just drank the koolaid). Regarding v6, there is nothing new, but we have seen issues with multicast that we've been able to replicate on both WiSM1s and WiSM2s, and also on the 7.0.116.0 and 7.4.100.60 codes. Basically, a user will obtain an IPv6 address. When the user moves to another AP in the same controller, that user no longer receiver RAs. We've tested this with the WiSM in multicast-multicast mode. Our only solution that we've found at the moment is to disable multicast on the controller, and surprisingly, that works. But if we do that, we can take advantage of the new Bonjour gateway feature. I won't go into that cause it just gives me headaches.
