In my small LAN of about 50 users, I have two domain controllers -- one Win 2003 and one 2008R2. DHCP role is on the 2003. I'm trying to "migrate" the DHCP from the 2003 to 2008R2 with the following steps:
1. install DHCP role on the 2008R2
2. Set up scope as 10.10.10.100 - 180. (while the exiting 2003 DHCP scope is 10.10.10.20-99)
3. Disable DHCP on the 2003
4. Enable DHCP on the 2008R2, and hope all users will automatically obtain the new IP from the new DHCP server while their current lease expires.
Will the above steps be working?
