I suggest you start by reading the Samba wiki:


There is a specific page to do what you want:


You will only need info from the PDC (note: once you have your first AD
DC up and running, don't call it a PDC, just call it a DC)

You can then join the second DC to the first, see here:


Can I suggest you test all of this first, do not let any of your
production machines connect to the test DCs, they will not connect to
your NT4-style PDC again.

Once you are sure everything is working, you can then do it for real.

Any problems, ask here.
