we have a very old ( 3.0rc4 ) dhcpd Server on a SLES 8 and want to  
migrate to a current version and a new server.

Is there documentation available on how to do this and what are the pitfalls.

Is it possible to migrate the actual dhcpd.leases file the way the  
machines continue to get the same IP as they have now ?
I discovered that for a reason I don't know for certain MAC addresses  
there are more then one leases in the dhcpd.leases that have a past  
"ends". Is there a tool to clean the file ? cleane_leases.pl does not  
work because without -f it does not delete the decayed leases and with  
-f it deletes leases it should not.

Thank you very much
