You cannot just transfer AD to another server.
Install the server as an additional DC of an existing domain, and let it
replicate, then DCPROMO the old server so that it is not longer a DC.
Would you explain a little more ?
I've already installed it as a DC with the same domain name but it's not
to the network. What to do now ? DCPROMO the new server then re-configure it
as an additional DC of the domain ?
How to let it replicate ?
