Migration DHCP from Windows Server 2003 to Windows Server 2008 R2
I am planning to migrate DHCP server from x86 2003 to x64 2008 R2 server. As far I know there is few ways to do it. I mention all of 3 different ways as far I know but not sure whether all 3 different ways are correct or not? Please advice which way is best way to do it.
1. Using "Backup" option from Source DHCP server and "Restore" option to destination DHCP server.
2. Using "netsh" dhcp server export and import command
3. Migrate DHCP server using "Windows Server Migation Tool"
I found last method is complex then other 2 methods. Just wondering method 1 or 2 will work to migrate the DHCP server or those 2 method will give me trouble? Which method is the best? Thanks.
