Yes, that's what you need to do.

The leasefile contains absolute timestamps, so make sure that the clocks
on the two servers are reasonably synchronised. A few minutes won't
matter, but if the clock on your new server is days ahead of the old one
then the first thing that happens when you start dnsmasq will be that it
 expires all the leases and deletes them :-)

Simon.
