[cisco-voip] DHCP Behavior

I'm getting ready to start migrating ip phones off of the DHCP service on
our callmanager to a DHCP appliance (infoblox). I've got the lease timer
down to 1 hour now on my first set of phones, my next step is going to be to
change the ip helper-address on the routers and deactivate the scope in DHCP
on the windows box.

How do the phones behave when they try to renew and their original DHCP
server isnt there? Do i need to reset all of them, or will they find the new
server on their own?
