Preserving lease database after enabling failover feature

I have a setup of two DHCP servers running the latest 3.0.4 version.
Currently a subnet is split into half with each DHCP server
allocating IP from its own half. It is sort of a primitive load-
Now I intend to move both servers to DHCP failover mechanism with
shared and the complete subnet. Everything works during the testing,
however my goal is to do the migration to failover by preserving
existing leases. I don't want to delete lease database before
enabling the failover feature on both servers. Is it possible? If so,
how it should be done? I have noticed that existing standard leases
are converted to failover format, however they may not be offered in
response to a DHCPDISCOVER request. Somehow the server offers a
different IP, even though the original IP is in the database.
