by not stable do you mean it is not at all working? if it is working for sometime you should transfer the roles to the secondary server to be on safer side. then you can promote the new server and demote this faulty server.

Don't restore.  Odds are you can't anyway (licensing) and then you'd need appropriate software.

You also don't have a primary and secondary.  In Active Directory, DCs are multi-master, meaning that each DC is equal.  There are 5 FSMO roles that could be spread amongst up to 5 servers.  If the currently unstable server is holding the roles, then TRANSFER them.  It's a fairly simple procedure, see:
http://www.petri.co.il/transferring_fsmo_roles.htm

What you want to do is:
0. Perform a full backup of both/all DCs!
1. Run DCDIAG /C /E /V on both DCs and confirm the directory health - resolve any unexplained issues
2. Install the new server as a member server.
3. Run DCPROMO on the new server and make it a DC.
4. Transfer the FSMO roles if necessary from the old server.
5. Run DCPROMO on the old server and demote it.
6. Delete the old server from the domain.

This WILL require changing the server name.  If you want to keep the server name, change the order from ... 2, 3, 4, 5 to 4, 5, 2, 3 and skip 6.

The best way to introduce a new DC is to run the DCPROMO command on a freshly built Windows Server.
When you restore the DC from the backup, the database will be out-of-date, and this can introduce more issues.

To get rid of the DC that is "totally down" you need to run a metadata cleanup:

Follow the instructions for ntdsutil in windows 2003.

Once the DC has been removed, you format and re-install Windows on your Server.(the totally dead one)
Then run DCPROMO to make it a Domain controller again.

But before you do the above, first confirm that the working Domain Controller currently holds all the FSMO roles.
If neccessary you make need to seize the roles.

The dead DC is dead. You don't work on it.
You must run the metadata cleanup on the Domain Controller that is still working.

No need to run Metadata clenup on dead servers.

Just go the DC which is up and running and perform metadata cleanup using NTDSUTIL

You just need to clean the references of the Dead DC.

Refer below link which explains how to perform Metadata cleanup.

Hope this helps.
