DHCP Authiorization troubleshoting Windows 2003/2008

Nowadays often DHCP has to be migrated on new servers, sometimes this should be tricky most times for a wrong procedure so here some steps:

1. dump existing dhcp configuration on source server:
open elevated command prompt and type 
netsh dhcp server \\ export [ip scope]

2. unauthorize server on source server
3. stop dhcp server service and disable it from autostart
4. install new role in the server and do not configure.
5. import configuration in new server:
netsh dhcp server %computername% import
6. start server 
7. authorize
8. make service DHCP auto start


if some troubles come up, like "unable to autorize" or "server already authorized" you should retry the authorization with this useful window:
