    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

  2. 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

    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.

  4. 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.
