HI All

I have to move all the scopes from 1 DHCP scope to another DHCP scope which
is already holding 2500 Scopes

What i mean is I have 2 DHCP server say Server1 & Server2 both holding
approx 2500 Scope each

Now i have to move DHCP scopes from server1 to server2 without impacting the
scopes on Server2

I am ware of the utility called dhcpexam used for migrating scope but not
sure if it can migrate to exisiting DHCP Server

Any quick help will be much appreciated

Hi Tarun

DHCPEXAM should be DHCPEXIM (Export Import) works fine for NT, 2003 does not
like it if I recall

Rather use NETSH command line tool with the "netsh dhcp /?" for more syntax
info

Rather use NETSH to export, then import to the scopes to the new server. Are
you sure that there are no scopes set the same on bot servers for redundancy,
50/50 etc.

Hello Tarun,

Depending on the OS version, which you didn't mention, you can either use
DHCPEXIM up to windows 2000 and netsh dhcp server export / netsh dhcp server
import commands since windows 2003.

DHCPExim:

We are moving from Microsoft to InforBlox and netsh has worked just fine for
us. Only problem is you have to clean up your scopes, I can almost
guarantee you will have junk in there that your destination server will
reject. You won't be able to find out until you do the migration. We went
a few subnets at a time. We have about 500 and it took several months.
