Changing to AD Integrated DNS

I have a four DC's running DNS in a Primary/Secondary configuration.  I'm planning on migrating to an Active Directory Integrated configuration as follows:
1. Change the primary server first. Stop/Restart DNS Service
2. Change the secondary servers.  Stop/Restart DNS.

Will it really be this easy?  Or am I going about this all wrong.  I've read the MS articles...and they don't really get into migrating secondary DNS servers.  I appreciate any/all advice!

Regards!

It really is that simple.  What you are doing by going to AD integrating is making the DNS database part of AD........so that rather than replicating DNS info between the DNS servers seperately, changes replicate as part of your AD replication...which is somewhat lower in bandwidth overhead.....the system really does work very well.......the other benefit is that when you bring another DNS server on line, you don't have to set up and and replicate zones....you just select AD-integrated on the new server.
Good Luck

As the previous poster says: it really is that simple.

With AD integrated zones, you do not really have secondaries any more - every server is a primary and thus can be updated directly. Changes are then replicated using AD integration.

When switching to AD integration, it can take 10-15 minutes or longer to replicate. You can use ADSIEdit to look for the objects as they hit the directory, or use replmon to push the updates along.

Thanks you both for the answers.  

JConchie - While your response was informative, I felt that the second answer did provide me with "Experts Exchange" type information that could potentially be useful in my DNS plans.  I apologize if you disagree.  

Additionally, I posted this same question to another newsgroup and was advised exactly how to facilitate the change so that I was sure that AD replication worked.

1. On Primary DNS Server, change zone to AD Integrated. Ensure that the secondary name server is listed on the Name Servers Tab of the Zone Properties.
2. On Secondary Server, delete the zone file.

Replication will occur within a few minutes.

Computer101 - Please don't change my accepted answer!

Thanks again!!!
