Synchronize Data from one CRM organization to another CRM organization

Hello CRM Folks,

Setup: Dynamic CRM 2015 Onpremise with 2 Organizations(Org A and Org B) with IFD Access.

Scenario: Whenever a Account or Contact Record is created in Org A, create the same record in Org B.

Could anyone link to me right direction as how to achieve this scenario?

I tried creating a record but i face Trust Issues. I think it is due to the Certificate, but not sure. Its says request failed.

ClientCredentials credentials = new ClientCredentials();
                credentials.UserName.UserName = UserName;
                credentials.UserName.Password = Password;
                Uri serviceUri = new Uri(SoapOrgServiceUri);
                OrganizationServiceProxy proxy = new OrganizationServiceProxy(serviceUri, null, credentials, null);
                proxy.EnableProxyTypes();
             
                service = (IOrganizationService)proxy;

Here is the code i have used, but i dont think its right. 

Let me know Guys!

Thank You!
