[Samba] How to Replace Production Samba AD DC Server with New Server

[vikas]

Hello all,

OS=CentOS 6.3 64 bit
Samba = 4.1.5
Samba compile and domain option used:

$ ./configure --enable-debug --enable-selftest
$/usr/local/samba/bin/samba-tool domain provision --use-rfc2307 --interactive

I want to replace my running samba server hardware with new server.
How should i approach this. One thing which is on my mind is below.

Install samba on new server with same compile option used on old with 
different ip address and subnet since the new is running and then change 
the ip address. And copy /usr/local/samba from old to new. Will this work ?

OR is there any smart and more elegant way to do ?

PS: i am using internal dns of samba, and there are about 100 users on 
domain.
