We are splitting our windows 2003 DHCP scopes (20 scopes in total) and moving them to two new 2008 DHCP servers (to retire the old 2003 DHCP server)
We are trying to decide whether we need a maintenance window for our 24/7 1000 node environment.
Let’s say the scope 192.168.1.0 is already leased to DHCP clients by DHCP1, so we come and exclude it from DHCP1 and Add it to DHCP2 and DHCP3 (80/20) should we expect any interruptions or conflicts for the clients with such a move? Or is it gonna be completely transparent for the clients.
Any one can share a previous experience for a similar change?
