Downgrade DHCP database (scope) from Windows Server 2008 to Windows 2003
Downgrade DHCP database (scope) from Windows Server 2008 to Windows 2003
If you only need to transfer DHCP configuration settings to Windows Server 2003, you may consider performing the following steps:
1. Dump the configuration of the source DHCP server by using the “netsh dhcp server <x.x.x.x> dump >c:export.txt” (without the quotation marks) command from any Windows 2008-based DHCP Server, where <x.x.x.x> is the IP address of the source DHCP server.
2. Clear the Option definitions off of the destination DHCP server.
3. Copy the Export.txt file to the destination server, and then rename the file to c:Import.txt.
4. Edit the Import.txt file with Notepad.exe and replace the IP address of the source DHCP server with the IP address of the destination DHCP server. Perform a Replace on the string “SERVER <x.x.x.x>” with “SERVER <y.y.y.y>”, where <x.x.x.x> is the source DHCP server address and <y.y.y.y> is the destination DHCP server address. IMPORTANT: Do not just string replace the “x.x.x.x” with “y.y.y.y” as either address may be used in option values within a scope. Save your changes.
5. If the DHCP database name or path on the Source server is different than the database name or path on the destination server, you must edit the Import.txt file to correct the values for any or all of the following settings: AuditLog, DatabaseBackupPath, DatabaseName, and DatabasePath. Note that the default path is typically c:winntsystem32dhcpDhcp.mdb. Save your changes.
6. Load the Import.txt file into the destination DHCP server by using the “netsh exec c:Import.txt” (without the quotation marks) command.
