migrate DNS from Windows 2000 to AD integrated Windows 2003

I have DNS running on two Windows 2000 servers, one primary and one secondary.  Each of these Windows 2000 servers is a AD domain controller; but DNS is not running as AD integreated.

I have added a new Windows 2003 server as a AD domain controller, and would now like to migrate DNS to this new 2003 domain controller and make DNS AD integrated.  Once I have that working I will also be adding a 2nd Windows 2003 DNS AD domain controller and add DNS to that server.

1.  Could someone please provide me with the steps to setup/add the Windows 2003 server into DNS, AD integrate DNS, and then remove DNS from the two Windows 2000 servers?

2.  Also, how will this impact current Windows clients and Exchange mail traffic, etc.?  I need to be able to make this transition without bringing down the corporate LAN for a whole day.

Thanks.

I believe you should be able to just change the zone type to "AD inegrated" on the exisitng primary.  

Here you go:

"Enable Active Directory Integrated DNS (Optional - Recommended)
Active Directory Integrated DNS uses the directory for the storage and replication of DNS zone databases. If you decide to use Active Directory Integrated DNS, DNS runs on one or more domain controllers and you do not need to set up a separate DNS replication topology.

In DNS Manager, expand the DNS Server object.

Expand the Forward Lookup Zones folder.

Right-click the zone you created, and then click Properties.

On the General tab, the Zone Type value is set to Primary. Click Change to change the zone type.

In the Change Zone Type dialog box, click DS Integrated Primary, and then click OK.

The DNS server writes the zone database into Active Directory.

Right-click the zone named ".", and then click Properties.

On the General tab, the Zone Type value is set to Primary. Click Change to change the zone type.

In the Change Zone Type dialog box, DS Integrated Primary, and then click OK.

Then I would say remove the secondary from the second server and add another Ad integrated.  For your third server build it pointing at one of the other DNS servers then set it will take the AD integrated zone too.

Keep a copy of the zone files from \winnt\system32\dns just in case...

i agree, since they are both DCs already, it is really easy.  Just create or modify their exising zone to AD integrated and you are done.

no need to mess with all that primary/secondary BS.

but remember, on the client end, one DC's IP will need to be listed as the 'primary DNS server' and the other will need to be listed as a 'secondary DNS server'.  this is done on the properties of the NIC.

Can I add the new Windows 2003 AD server into DNS as a secondary server, and then once it has all the zones can I switch that 2003 DNS server from secondary to Primary/AD integrated?  How would this impact the current Windows 2000 DNS server that is set as primary?

I would like to leave the Windows 2000 DNS servers alone until I have the 2003 DNS server up and running - basically, if possible, I want to make sure that things are running fine on the 2003 server first.  I guess what I need help with is the steps involved to make this 2003 server AD integrated...and not break the current DNS in the process.

Thanks,
Patrick

One other thing: is there an easier way to create the DNS zones/records on the 'new' Windows 2003 DNS server, other than creating each one manually?  I have 24 forward zones and 8 reverse zones, and I'd like to be able to simply have all of the zones copied/created on the new server - is this possible?
Just make your existing one ad integrated, then all the zones will come across anyway.

Okay, so you are saying that I should take my Windows 2000 'primary' DNS server and AD integrate it first.  Then what?  Will the secondary Windows 2000 DNS server automatically get AD integrated?  What about setting up/adding the new Windows 2003 DNS server.

Sorry, but could  you be more specific with instructions about which server and what steps to complete on each?  Thanks.
