OK, stupid mistake of the week.

The frustrating problem was that the clients kept getting the old
router's IP address. This was for the simple reason that I had managed
to not change the value of the "option routers" entry for the subnet.
Doh! I have fixed that. Never be afraid to recheck your own work.

I did shorten the lease times and that has accelerated the changeover.
I didn't need to restart all the client's leases. Two days hence I'll
change them back.
