"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Computer account migration will automatically create these dns values. for DHCP you can restore database to new and enable scope. Disable DHCP from old before enabling on new.
I have used this in the past for DHCP migration


It works well and even on the later OS versions.

As stated above you should disable DHCP on the source.  You then need to adjust the scope/server options within the DHCP console to point to the new values for DNS, then activate the scope.
To avoid any issues with conflicting IP addresses it would be advisable to enable conflict detection on the DHCP server properties.  This basically sends a ping message out to the IP that is about to be assigned before assigning it to make sure it is not in use - keep it enabled for 24 hours then disable it again.

As stated above DNS will replicate naturally as will the AD objects

You can promote the DC as DNS server while promoting in new forest or while migration from Windows Server 2000/2003 to Windows Server 2008/2012,etc. While promoting ensure that you check the dns and GC role. In case if you have missed it install the dns role and ensure the correct dns setting in NIC properties the dns zone will be replicated.

IF the DC are on the same Domain and are AD integrated there is nothing to do. All records / zones are replicated between DC's in the same forest / domain depending on your replication scope
