I'd suggest trying Kea, the ISC DHCP server that's undergoing active 
development. There's a tool to migrate the old configuration to the new 
JSON format. Alas, there's no tool to migrate the lease file. That sounds 
like a big obstacle for migrating big sites or testing the new software 
against a big existing deployment database.
