I need to upgrade two file servers to samba 4.

Server 1 -> Centos 6.1 (NT Style Domain Controller)
Server 2 -> Centos 6.8 (member server)

I have added a new server (ie Server 3) than is
running Debian and Samba4 configured for AD.

Computers and Users can authenticate to the new
server and new domain.  Group Policy, share and
drive maps work.  The new setup in a "test scenario"
seems to be working properly.

What is the best way to move the file servers
over to the new version of samba?

I'm thinking the following:

1) Remove samba3
2) Install samba4
3) Modify smb.conf for the required file shares
4) Join each server to the AD Domain.
5) Assign share/file permissions via windows.
6) Map new drives via Windows group policy.

Seems simple.  Usually isn't.  Thanks.

1) Copy all data to Server2
2) Install Debian on Server1
3) Use latest Samba from here: http://apt.van-belle.nl/
4) Set up and join Computer to domain
5) Once you are sure all accounts have the correct ID's, copy all data
    to this Unix domain member aka fileserver
6) Install Debian on Server2
7) use latest Samba from here: http://apt.van-belle.nl/
8) Set up and join to domain as a second DC


What's the reason for changing distributions?
We're talking about gigabytes of data (ie 113 Gb)
That's a task I'd rather not tackle if not required.
