5)使用以下命令行在windows2003dhcp服务器上删除注册类：
---------------------------------------------------------
netshDhcpServer172.17.88.103deleteClass"默认路由和远程访问类别""远程访问客户端的用户类别"525241532e4d6963726f736f66740b
netshDhcpServer172.17.88.103deleteClass"默认BOOTP的类别""BOOTP客户端的用户类别"424f4f54502e4d6963726f736f66740b
netshDhcpServer172.17.88.103deleteClass"MicrosoftWindows2000选项""Windows2000客户端的Microsoft供应商特定选项"4d53465420352e301b
netshDhcpServer172.17.88.103deleteClass"MicrosoftWindows98选项""Windows98客户端的Microsoft供应商特定选项"4d5346542039381b
netshDhcpServer172.17.88.103deleteClass"Microsoft选项""适用于Windows98和Windows2000客户端的Microsoft供应商特定选项"4d5346541b
---------------------------------------------------------
6)copy出windows2008R2dhcp服务器导出的文件相应注册类内容，并修改主机或ip名称以适合windows2003服务器使用
-内容B--------------------------------------------------
netshDhcpServer172.17.88.103AddClass"DefaultRoutingandRemoteAccessClass""Userclassforremoteaccessclients"525241532e4d6963726f736f66740b
netshDhcpServer172.17.88.103AddClass"DefaultNetworkAccessProtectionClass""DefaultspecialuserclassforRestrictedAccessclients"4d5346542051756172616e74696e650b
netshDhcpServer172.17.88.103AddClass"DefaultBOOTPClass""UserclassforBOOTPClients"424f4f54502e4d6963726f736f66740b
netshDhcpServer172.17.88.103AddClass"MicrosoftWindows2000Options""Microsoftvendor-specificoptionsforWindows2000andaboveClients"4d53465420352e301b
netshDhcpServer172.17.88.103AddClass"MicrosoftWindows98Options""Microsoftvendor-specificoptionsforWindows98Clients"4d5346542039381b
netshDhcpServer172.17.88.103AddClass"MicrosoftOptions""Microsoftvendor-specificoptionsapplicabletoallWindowsClients"4d5346541b
------------------------------------------------------
7)在windows2003服务器上以cmd方式运行内容B，在windows2003上注册修改后windows2008R2的类。
使用命令netshdhcpserverdump检查是否新类被注册在windows2003的服务器上！
8)在Windows2003服务器上运行：Netshdhcpserverexportc:\dhcp.txtall
9)在windows2008R2服务器上停止windows2008R2的dhcp服务。
10)在windows2008R2服务器下删除windows\system32\dhcp目录下的DHCP.mdb数据库。11)在windows2008R2服务器上启动windows2008R2的dhcp服务。12)在windows2008R2服务器下运行：netsh dhcp server import c:\dhcp.txt
导入到2008R2后，需要检查内容是否完整，需要手工补全！（我迁移时发现，路由、dns、ip地址范围、排除ip均有问题，不过大框可以迁移过来，避免手工量过大）
