Did the cutover the other night and so far has been working very well.

We shut down both dhcp servers, copied the lease file from the
secondary to all the "new" secondaries, and started things up. A big
flurry while each of the new secondaries deleted all the leases that
were for other networks and it started working straight away - didn't
have to wait for MCLT to expire or anything.
