windows server dhcp server and cisco switches

hi,

i have 2003 dc running dhcp using ip-helper for multiple vlans on cisco switches. there is domain trust between 2003 dc domain and new 2008 domain. I want the 2008 to be dhcp server.

will i have to make the change over out of hours to avoid ip conflicts? and what is best process.?

thanks

You can simple set up the 2008 with another usable DHCP ip range then once the 2008 DHCP is up turn off the 2003 DHCP service. Once all workstation on the new DHCP then remove/uninstall the old DHCP service completely.

Which you can perform it at anytime.

As always, with Cisco, you got a lot of reading to do. :P

And yes, you can do one vlan at a time.

Would it not be easier to move the dhcp database to the new server?

@ bill, Yes. He would still need to configure the relay agents on the switches in order to work with the new IP address of the server.

I would only recommend this if you have an unusually large number of DHCP reservations.
