Switchover went smoothly. I stopped CM service before disconnecting the old nodes to try and clear out tcp sessions out on the ip phones. Still took a few minutes for phones to all register and settle down on the primary CM.
2 nearly identical MGCP gateways on site - same IOS, basically the same MGCP config and network connectivity. One of them would not re-register so I ended up reloading it, after which it registered fine.
