I would first break the failover by shutting down (and disabling)
DHCPD on the secondary server then on the primary server set it into
partner down, that way it will make sure the leases file is "tidy" and
that the primary server then has full control of the lease pools. Then
copy across the config (sans failover) and leases file to the new
DHCPD server and start it up.

Don't forget to tell the network team to clean up the network config
to remove any forwarders which have been added for the secondary
server that is no longer there.
