The REXX Script converts a DHCP Server dump file created from the "netsh" dump command into an ISC DHCP Server configuration file.

This script can be used as a starting point to migrate a Microsoft DHCP Server from Windows to Unix.

Code:

This script requires a REXX Script interpreter such as Regina Rexx: http://regina-rexx.sf.net

In order to migrate a Microsoft DHCP Server scope onto an ISC DHCP Server on Linux or Solaris, there is an even simpler way using the Men & Mice Suite:

* install the Men & Mice DHCP Server Controller on the ISC DHCP Server

* install (temporary) a Men & Mice DHCP Server Controller for Windows DHCP. This can be done on the DHCP Server itself, or on any server or client machine that is part of the same AD. Make sure the DHCP Server Controller runs under an user account that is part of the "DHCP Administrators" group.

* add both DHCP Server to the Men & Mice Suite

* select the Scope on the Windows DHCP Server, select "Migrate Scope..." and migrate the scope including options and reservations to the ISC DHCP Server

The same trick also works in the opposite direction, from ISC DHCP to Windows DHCP.

A dump of a Microsoft DHCP Server can be done from the commandline with this command (the resulting dump will be in the file dhcp.dump)
Code:
 netsh dhcp server \\name_of_server dump > dhcp.dump


Such a dump look similar to this
Code:

Here is a variation of the script that reads a Microsoft DHCP Server dump file and converts it into a command file for the Men & Mice CLI (mmcmd).

Using the mmcmd, the configuration can then be imported to any of the supported DHCP Server types in a Men & Mice System (Windows DHCP, ISC DHCP and Cisco IOS DHCP).

This script requires a REXX Script interpreter such as Regina Rexx: http://regina-rexx.sf.net

Code:
 /* Convert Script MS DHCP Dump to Men & Mice DHCP Configuration Script */
   
   PARSE ARG server infile outfile servertype
 
   useroptions = " 60 137 161 162 176 201 252 "
   
   dhcpproduct = "ISCDHCP"

Example use of the script:

Code:
 
 C:\Users\Administrator\Desktop\DHCPmigrate>rexx msdhcp2isc win2k8v6.home.strotmann.de dhcp.dump
 Men & Mice MS DHCP -> mmcmd script Converter
 (c) 2010 Men & Mice, CAS
 --------------------------------------------
 
 DHCP Server      :    win2k8v6.home.strotmann.de
 MS DHCP Dump File:    dhcp.dump
 mmcmd Script File:    dhcpimport.mmc
 4 Scopes processed
 4 Reservations processed
 Convert finished.


And then

Code:
 
 C:\Users\Administrator\Desktop\DHCPmigrate>mmcmd -s <mmcentral> -u administrator -p <password> -f dhcpimport.mmc
