Title: Re: [ActiveDir] DHCP migration(OT)

I agree with Daniel – I believe that netsh will do a fine job of migrating scopes and scope options but not leases.  However, leases should not be too much of an issue so long as you instruct the DHCP server to perform conflict detection (assumes that ICMP is not blocked on your network).   A set of commands something like the following perform the migration for you.   From a command prompt on the existing DHCP server: Netsh  dhcp  server  \\existing_dhcp_server  export  c:\dhcp_info.txt   all   From a command prompt on the new DHCP server: Netsh  dhcp  server  \\existing_dhcp_server  import  \\existing_dhcp_server\c$\dhcp_info.txt   all   Now keep in mind that this will export everything and import everything.  I would suggest ensuring that the new DHCP server is at the time of import not authorized in the AD or at least in a state that no clients will attempt to use it.  After the import you can retrofit any of the imported data as necessary, such as altering or removing scopes or options.   If you need to be more selective about what you export from the existing server, you will want to use the dump command instead and the massage the output so that you can use the add command on the new DHCP server.   HTH   Aric       From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Conrad, Daniel C Mr. Nortel Government Solutions Sent: Tuesday, May 16, 2006 9:50 AM To: ActiveDir@mail.activedir.org Subject: RE: [ActiveDir] DHCP migration(OT)   Past experience,   NETSH will migrate the scopes but you use the backup/restore process for the leases (if you want them).   D   From: [EMAIL PROTECTED] on behalf of Matheesha Weerasinghe Sent: Tue 5/16/2006 8:43 AM To: ActiveDir@mail.activedir.org Subject: Re: [ActiveDir] DHCP migration(OT) Havent played with it for a while so I cant answer unless I fire up a VM and start playing.
