Hi
There seems to be a number of ways to migrate DHCP from 2003 to 2008R2 and, to me at least, some conflicting stories on what’s best. We’re moving from a 2003 DC running DNS and DHCP to a newly promoted 2008 r2 x64 server running as a DC and DNS.
I found this articlehttp://www.networkworld.com/community/node/56296
about using the DHCP migration tool in 2008 r2 and it looks just like what we need. The only thing is it reuses the IP address from the old/existing DHCP server. We’re not reusing the IP address on the new DHCP server, the new DHCP server will have a NEW IP address.
My questions are:
- What happens when we use a new IP address for our DHCP servers? We don’t want to have to reboot every client.
- I’ve read we could shorten the lease time to 30 mins on existing DHCP server. Assuming this is correct; at what stage in the process would we do that?
- I also understand that we need to update the IP helpers on routers, I guess we do this after after the last step?
Apologies if these questions seem daft/obvious. I would have thought what I’m doing is not to left field but I can’t find any definitive articles for DHCP migrations (using DHCP migration tool in 2008 r2)to servers with a NEW IP address.
I’ve found this very similar article but it doesn’t actually say what happens for using a new IP address
