OO - Licenses for DC instance will work for DR

Hi Team,

We have installed the OO Central in DC and We have applied the license to OO Central.

Now We have plan to install OO Central in DR. We will replicate the DC database and installed the Central in DR by following Add a node to the existing Central cluster setup. 

In the above scenario, Do we required additional License for DR Central or it will work with DC Central License?
