How fast the Switches can recognize the new mac? Any other pitfall?

within seconds. or faster. and the client's ARP caches expire nearly as fast.

its not the switches you care about as much as the DHCP leases for your clients. if you can copy the dhcp leases file over, that will save a lot of grief.

I would suggest installing new gateway as new system, leaving old one to work until new one is ready. That way if something goes wrong you will still have old one to revert to. Just do not give in working IP's until you are ready to switch over.
