Command comments:

Export-DhcpServer [- File] [- ScopeId] [- Prefix] [- Leases] [- Force] [- ComputerName] [- CimSession] [- WhatIf] [- Confirm] [] if you specify the ScopeId or Prefix parameter, only the specified range or prefix and all server-level settings are exported. If neither ScopeId nor Prefix is specified, the DHCP server service configuration (including all ranges, V4 and V6, and optional lease data) is exported. If you specify the Leases parameter, lease data is exported in addition to the configuration data. Example 1: export all DHCP configurations Export-DhcpServer-ComputerName "dhcpserver.contoso.com"-File "C:\ exportdir\ dhcpexport.xml" Import-DhcpServer [- File] [- BackupPath] [- CimSession] [- ComputerName] [- Force] [- Leases] [- Prefix] [- ScopeId] [- ScopeOverwrite] [- ServerConfigOnly] [] if ScopeId or Prefix parameters are specified, or ScopeId and Prefix parameters are specified, only the specified range or prefix will be imported. If the ScopeId and Prefix parameters are not specified, all configurations contained in the file and any optional lease data are imported. If the Leases parameter is specified, the lease data from the specified file is imported in addition to the configuration data. If the ScopeOverWrite parameter is specified and the scope being imported exists on the target server, the scope on the target DHCP server service is overwritten. If this parameter is not specified and the scope being imported exists on the target DHCP server service, a warning message appears that the import will continue to process the next scope being imported. If the ServerConfigOnly parameter is specified, the server-level configuration is imported only on the target DHCP server service. If the specified file contains any scope information, the same information is not imported on the target DHCP server service.
