Windows Server 2003 AD & DNS migration

Experts
I have 3 existing windows 2003 domain controller for my domain.
2 of which have DNS installed on them and 1 of them has the DHCP for the LAN

My question is this

I have now built 2 new Windows servers and i am going to make these domain controllers which is fairy straight forward. however i want to retire the 2 olders servers which hold the DNS.

Do i make my 2 new servers Active Directory servers now using the dns info for the older 2. Then make the 2 new servers DNS servers. Then remove DNS from the older boxes and AD etc.

Because AD is tied in with DNS and DHCP with DNS etc i want to see what the best way is.
I will be creating a new DHCP pool on the new server. DNS entires for the new DHCP will be the new DNS servers.

Thanks

When you promote the 2 new Servers to Domain Controllers, install the DNS Role on both Domain Controllers. DNS will then replicate to the new Domain Controllers. It is very important to know which Server or Servers is holding the FSMO Roles. You will need to transfer these Roles. Presumably the old DCs are Global Catalogs so make sure that the 2 new Domain Controllers are also Global Catalog Servers. Active Directory publishes the information within Active Directory to the Global Catalog, such facilitating oject searches, upn names, etc. One of the FSMO Roles - the Infrastructure Master updates it-self from the information in the Global Catalog.

Should i point the 2 new servers to the existing DNS servers
Then install AD and then DNS

You will have to have at least one of the old servers listed in the DNS properties on the new sevrers so it can see the domain and be promoted to DC.
