Regarding the management IP, as long as you don't absolutely have to use the management network interfaces, you can just manage the device through any of the floating IPs configured. You may need to make some adjustments to the Port Lockdown settings of the Self-IP you wish to use depending on what's configured now. Allow Default should do the trick.
